The mode switching button 257 is displayed at the center of the jog dial display unit 220, and is a first display mode for performing a special operation capable of performing a scratch operation described later, and a second display performing a direct operation capable of a sound skipping operation described later. It is a button for switching the mode to one of the modes. The mode switching button 257 is displayed in white when the mode is the first display mode, and is displayed in color when the mode is the second display mode. Note that the mode switching button 257 in FIG. 5 is shown in white as a display during the first display mode, and the mode switching button 257 in FIG. 13 is colored as a display during the second display mode. In this embodiment, the first display mode is set as the “special operation mode” and the second display mode is set as the “direct mode”. However, the present invention is not limited to this. That is, any display mode can be used as long as the display mode is changed by the display switching button.

Further, as shown in FIG. 7, when the jog dial display unit 220 is rotated by touching the jog dial body 12a, the rotation speed of the beat position image 252 changes in the same manner as the physical rotation speed of the jog dial body 12a. Let That is, the beat position image 252 rotates in synchronization with the rotation operation while touching the jog dial body 12a. Further, when the jog dial main body 12a is pressed, the reproduction speed is reduced for a predetermined period, and the reproduction state is stopped. When such a rotation operation and a stop operation are performed, eight master beat position images 262 that continuously rotate at the rotation speed before the operation are displayed are displayed (see FIG. 5B).

In addition, the playback speed of the music changes in synchronization with the rotation operation while touching the jog dial body 12a. A so-called scratch sound (pseudo sound) is reproduced along with the change in the reproduction speed. Thus, the operator can perform a scratch operation so as to rotate the analog record on the turntable by rotating the jog dial body 12a while touching it. When the 12b is rotated without touching, a pitch bend operation that can temporarily increase or decrease the reproduction speed is possible. In this case, the rotation of the beat position image 252 is fast and slow.

Next, the transition of beats to be played will be described. Note that the jog dial 12 in FIG. 8 omits the display of the configuration that is not necessary for explanation, and simply displays it. As shown in FIG. 8, the beat position image 252 displayed in an area (unreproduced area) from the reproduction position image 251 to a position that forms 180 degrees counterclockwise is an unreproduced beat position immediately before the reproduction position. The beat position image 252 displayed in the area (reproduced area) from the reproduction position image 251 to the position that forms 180 degrees in the clockwise direction indicates the reproduced beat position immediately after the reproduction position. That is, the beat position image 252 displayed on the jog dial display unit 220 is four beats before and after the reproduction position (reproduction position image 251) (four beats to be reproduced and four beats that have been reproduced). Further, the position where the lower end of the display area is 0 degree and is 125 degrees from the lower end is the boundary between the reproduced area and the unreproduced area. That is, as the beat position image 252 rotates, the beat position image 252 passes through the boundary between the reproduced area and the unreproduced area, and switches from the reproduced beat position to the unreproduced beat position. As shown in the figure, since the beat position image 252 is rotated continuously in one round, the above switching is performed smoothly in a series of rotation operations of the beat position image 252, as if the beat position image 252 It rotates at a constant speed before and after switching so that the image 252 shows the same beat.

For example, when it is desired to shift from the currently playing beat to another beat, as shown in FIG. 8A, if the destination beat position is four beats before and after the currently playing beat position, the reproduction position image 251 is displayed. Of the four beats before and after, the desired beat position image 252 that is actually displayed is directly touched and rotated to the reproduction position (rotation operation is performed while touching). In the figure, the transition from the currently playing beat to 2 beats before and from the playing beat to 1 beat later is illustrated. On the other hand, as shown in FIG. 8 (b), if the beat position of the transition destination is a beat position that is more than 5 beats before and after the currently playing beat position, it is not actually displayed, but the desired beat being displayed is displayed. If the corresponding beat position image 252 is touched and rotated to the reproduction position beyond the boundary between the reproduced area and the unreproduced area, the beat can be shifted. In the figure, the transition from the currently playing beat to 7 beats before and from the playing beat to 6 beats is illustrated. In addition, when the beat position image 252 to be displayed continuously is 8 beats, it is also applied to a beat that is 8 beats before (2 bars before) by 1 rotation clockwise and 8 beats (2 bars after) after 1 rotation counterclockwise. Easy migration. In this way, by touching the beat position image 252 corresponding to a desired beat and increasing the rotation distance (number of rotations), it is possible to easily shift to a beat position that is not directly displayed and is at least 5 beats before and after. Can do. That is, according to the jog dial display unit 220, beats around 4 bars and 6 bars can be recognized by the number of rotations. In addition, it is possible to easily grasp and shift beat positions before and after 4 bars and 6 bars which are not displayed. By moving the beats as described above, you can select various beats (sound sources) and select various rhythms while easily recognizing the shift to beats that are not displayed and the operation of shifting in units of measures in the scratch operation described later. Scratch performance to build is possible.

Next, referring to FIG. 9 and FIG. 10, the scratch operation using the master beat position display will be described in detail. FIG. 9 shows the operation when starting the scratch operation. In the figure, the jog dial 12 omits the display of a configuration that is not necessary for explanation, and simply displays it.

As shown in FIG. 9, during the music reproduction, the user touches the beat position image 252a indicating the desired beat position (see FIG. 9A), and keeps the jog dial body 12a in the counterclockwise direction (reverse reproduction direction). The beat position image 252a is moved to a position slightly ahead of the reproduction position image 251, and the position is maintained, and the scratch start standby is performed (see FIG. 5B). Note that it is preferable that the mixer device 20 cuts the scratch sound that is output when the beat position image 252a passes through the reproduction position image 251 by this operation. Then, at the timing when the master beat position image 262 that rotates at the speed before the operation overlaps the reproduction position image 251 (see FIG. 5C), the beat position image 252a is rotated clockwise toward the reproduction position image 251. (See (d) in the figure). At this time, a scratch sound is output when the beat position image 252a passes through the reproduction position image 251. In this way, the jog dial body 12a is rotated a plurality of times so that the beat position image 252a moves back and forth the reproduction position image 251, and scratch play is performed.

FIG. 10 shows an operation when the scratch operation is ended and the normal reproduction state is restored. As shown in the figure, from the state in which the beat position image 252a is in a position that has passed through the reproduction position image 251 (see (a) in the figure), the master beat position image 262 is overlapped with the reproduction position image 251 (same as above). (See FIG. (B)), the beat position image 252a is rotated counterclockwise so as to overlap the reproduction position image 251 (see (c) in the same figure). At this time, since the beat position image 252a overlaps the master beat position image 262, the display of the master beat position image 262 is erased (see FIG. 4D).

According to the above scratch operation, the timing at which the display positions of the beat position image 252a, the reproduction position image 251 and the master beat position image 262 all match is intuitively grasped, and the start of the scratch operation and the start of the scratch operation are synchronized with this timing. Since the operation can be completed, the rhythm can be easily kept before and after the scratch operation.

Next, with reference to FIG. 11 and FIG. 12, a juggling operation using the two players 10a and 10b will be described. As shown in FIG. 11, the players 10a and 10b connected to the mixer device 20 play the same music at the same timing, and the player 10a is the output target (the playback sound of the player 10a is output to the outside). The jog dial body 12a is rotated so that the beat position image 252a of the player 10b that is not an output target is delayed by two beats with respect to the player 10a (see FIG. 5B). )reference). At this time, the player 10b is in a playback state delayed by two beats with respect to the player 10a, but the playback sound of the player 10b is not output to the outside. Then, as shown in FIG. 12, the normal reproduction is continued (see FIG. 12C), and the crossfader 27 of the mixer device 20 is operated at the timing when the desired beat position image 252a passes the reproduction position image 251. Then, the output target is switched to the player 10b (see FIG. 4D). Furthermore, the output target may be returned to the player 10a side by operating the crossfader 27 at a desired timing. In this way, individual sound performance can be performed by repeating the operation of the crossfader 27 of the mixer apparatus 20.

According to the above juggling operation, the display and operation of the jog dial 12 can easily and accurately shift the playback state of the two players 10a and 10b by two beats and a few beats to change the rhythm, An irregular rhythm can be constructed. The display of 8 consecutive beats makes it possible to easily recognize and shift the operation in units of measures. In addition, the display of 8 consecutive beats makes it possible to select a variety of beats (sound sources) and build a variety of rhythms while easily recognizing shifts to non-displayed beats and operations for shifting in units of measures. Become. Furthermore, the master beat position display suppresses the rhythm shift of the players 10a and 10b as much as possible, and the juggling performance keeping the tempo becomes possible.

Next, a sound skip operation in the direct mode (second display mode) will be described with reference to FIG. As shown in FIG. 6A, when the mode switching button 257 displayed at the center of the jog dial display unit 220 is pressed (touched), the mode switching button 257 is displayed in color, and the mode is switched to the direct mode. In contrast to the special operation mode in which special operations such as a scratch operation can be performed, in this direct mode, playback stop, scratch operation, and the like are invalidated by touching. However, the rotation of the jog dial 12a is not locked. As shown in FIG. 5B, in the direct mode, when an arbitrary dot 259 of an arbitrary ring image 256a is touched, the playback position of the music changes to a position corresponding to the dot 259 of the touched ring image 256a. Playback is started as it is while keeping the tempo and beat (position designation part). In the special operation mode, the reproduction control function for skipping sound by touching an arbitrary dot 259 is disabled.

If the vicinity of the preset CUE point 260 is touched while the mode is switched to the direct mode, the music playback position jumps to the position indicated by the CUE point 260 and then the play / pause button 18d is pressed. Then, reproduction is started from the position of the music indicated by the CUE point 260. In addition, it is good also as a structure which can perform operation similar to when the CUE point 260 is touched by pressing down the CUE button 18c during reproduction | regeneration. On the other hand, when the vicinity of the HOTCUE point 261 is touched, the playback position of the music jumps to the position of the music indicated by the HOTCUE point 261 and playback is started as it is. According to this, a predetermined point for performing a sound skip operation can be easily grasped and skipped accurately. When skipped by HOTCUE, the tempo and beat are kept and continuous playback is performed. Furthermore, it is possible not only to skip to CUE and HOTCUE points in one song, but also to skip to CUE and HOTCUE points set for any song in the playlist.

In addition, the CUE point 260 and the HOTCUE point 261 can be set in advance by the operator. Actually, the CUE point 260 can be set by searching for an arbitrary point using the jog dial 12 or the manual search button 18b and pressing the CUE button 18c at the point. Further, in the HOTCUE record mode, a plurality of HOTCUE points 261 can be set by searching for an arbitrary point using the jog dial 12 or the manual search button 18b and pressing an operator (not shown) at the point. In direct mode, not only the CUE and HOTCUE points set in advance, but also any position of 256a of any song in the playlist during playback, keeps the tempo and beat and continuously plays. Is possible.

According to the above-mentioned sound skipping operation, the direct mode switching button display is located at the center of the jog dial 12, so after the scratch operation, the most recent button is pressed, the mode is switched, the mode is switched to any music and position, and the mode is switched again. Since it is possible to perform complicated performances such as pressing a button and continuing the scratch operation without diminishing the line of sight, the time lag of the operation can be minimized.

Next, the music selection operation will be described with reference to FIG. 14 and FIG. In the present embodiment, an operation using two players 10a and 10b will be described. As shown in the figure, the players 10a and 10b connected to the mixer apparatus 20 play an arbitrary piece of music, and the player 10a is the output target, and the crossfader 27 of the mixer apparatus 20 is operated to output the music. Is switched to the player 10b at a desired timing (see FIG. 14A). As described above, a desired (for example, “E”) playlist is dragged and dropped from the plurality of playlists displayed in the playlist display area 201 in a state where the playback sound is not output from the player 10a. Thus, the image is once moved to the standby playlist display area 201a and then moved to the position where the jacket image 254 in the jog dial display unit 220 is displayed (see FIG. 14B). As shown in the figure, a jacket image 254 of the playlist “E” is displayed in the jog dial display unit 220, and a song title 255 (not shown) included in the playlist “E” is displayed. Further, using the track search button 18a and the manual search button 18b, an arbitrary piece of music is selected and the playback position is moved to an arbitrary point. Then, with the playback position moved to an arbitrary point in the player 10a (see FIG. 15C), the output target is switched to the player 10a by operating the crossfader 27 of the mixer device 20 (FIG. 15D). reference).

According to the above music selection operation, it is possible to quickly switch between playlists and music to be played back by an intuitive drag and drop operation. For this reason, it is convenient when performing an acoustic performance involving other operations.

Next, the rising adjustment operation and the falling adjustment operation will be described with reference to FIG. As shown in FIG. 16, when the falling adjustment knob 102 is rotated in the clockwise direction, the apex angle of the falling reproduction image 258b increases and the area of the falling image 258b increases. Along with this operation, the curve of the output sound at the actual start of reproduction is set to be steep. Similarly, when the rising adjustment knob 103 is rotated in the clockwise direction, the apex angle of the rising reproduction image 258a is reduced, and the area of the rising reproduction image 258a is reduced. Along with this operation, the curve of the output sound at the end of actual reproduction is set to be gentle. When set by the above-described rising adjustment operation and falling adjustment operation, the playback speed deceleration period (fall time) from when the jog dial body 12a is pressed until playback is paused increases, and the jog dial body 12a is pressed. The acceleration period (rise time) of the playback speed from the end to the restart of normal playback is shortened.

According to the above rise adjustment operation and fall adjustment operation, the fall time and the rise time can be visually grasped by the change in the rise reproduction image 258a and the fall reproduction image 258b. That is, it is convenient when performing a performance such as a scratch operation in consideration of the fall time and the rise time.

In addition, when the player 10 of this embodiment operates various controls, the jog dial display unit 220 displays the points on the image indicating the operation results of the controls and the controls connected by lines (association display). ). FIG. 16 illustrates a case where the falling adjustment knob 102 and the rising adjustment knob 103 are operated. The association display of other operators is shown in FIG.

As shown in FIG. 17, when the play / pause button 18d is pressed, a waveform image of the sound that is temporarily stopped is displayed on the button, and a line image that connects the play / pause button 18d and the point on the reproduction position image 251 is displayed. Is displayed. Similarly, when the CUE button 18c is pressed, a waveform image of the sound of the CUE point 260 is displayed on the button, and a line image connecting the CUE button 18c and the CUE point 260 is displayed. When the track search button 18a is pressed, an image indicating the track search state is displayed on the button, and a line image connecting the track search button 18a and the song name 255 of a predetermined music is displayed. When the manual search button 18b is pressed, a waveform image indicating the search state is displayed on the button, and a line image connecting the manual search button 18b and the reproduction point on the reproduced image 253 is displayed. Further, in this case, an arrow image 253a directed in a predetermined search direction is displayed on the ring image.

As shown in FIG. 17, when the torque adjustment knob 101 is operated, a line image connecting the torque adjustment knob 101 and the central point of the jog dial display unit 220 is displayed. When the torque adjustment knob 101 is operated in a direction to increase the rotational torque of the jog dial main body 12a, the color of the circular frame image 270 surrounding the display area is changed in order to visually express the change in the rotational torque. . For example, the torque is expressed by the darkness of the color of the frame image 270, for example, the darker the color of the frame image 270, the higher the torque, and the lighter the lightness. On the other hand, when the tempo slider 104 is operated, a line image connecting the tempo slider 104 and the central point of the jog dial display unit 220 is displayed. Further, in this case, when the tempo slider 104 is operated so as to increase the tempo of the music being reproduced, a state in which the ring image 256b is enlarged is temporarily displayed. On the other hand, when the tempo slider 104 is operated so as to slow down the tempo of the music being reproduced, a state in which the ring image 256b is reduced from the outer periphery is temporarily displayed. In the figure, a case where the tempo slider 104 is operated to increase the tempo of the music being played back is shown.

Next, the music composition display screen 210B displayed on the main display unit 210 of the player 10 will be described in detail with reference to FIGS. FIG. 18 is an enlarged view showing the music composition display screen 210B. As illustrated, the music composition display screen 210B displays a music composition display image 212, an effect image 211, and a display switching button 292.

Based on the analysis result of the analysis processing unit 52, the music composition display image 212 is a piece of music data from the start (start) to the end (end) of the music being played back for each frequency band and one beat per region. The display is divided into a matrix for each (time band). That is, as shown in the figure, the frequency band (“Hi”) in the time band (1) corresponding to the first beat of the music indicates the divided region 221 and the frequency band (“Mid”) in the time band (1). Indicates the divided region 222, and the frequency band (“Low”) in the time band (1) indicates the divided region 223. Note that the music composition display image 212 has a predetermined display area, and the display area of the time band is determined so that the entire music can be accommodated. That is, the display area of the time band varies depending on the speed of the tempo of the music to be played, the playback time, and the like.

In addition, the music composition display image 212 represents the volume level of the music data corresponding to the divided area by the difference in the color in which each divided area is filled. In FIG. 18, the volume level of the divided area that is displayed with fine diagonal lines indicates “high”, the volume level of the divided area that is displayed with rough diagonal lines indicates “medium”, and is displayed in white. The volume level of the divided area is “low”. That is, referring to FIG. 18, the volume level of the divided area 221 is “low”, the volume level of the divided area 222 is “medium”, and the volume level of the divided area 223 is “high”. . It should be noted that “decoration according to volume level” in the claims means that each divided region is displayed in a different color according to the volume level in the present embodiment. Note that the method for expressing the volume level is not limited to the difference in color, and different display forms may be used as long as the difference in level can be recognized.

Also, the music composition display image 212 displays a band-like reproduced image 224 indicating a reproduced portion of the music data. As shown in FIG. 18, the band-shaped reproduced image 224 is a band-shaped image that covers a part of the frequency region “Hi”, all of “Mid”, and part of “Low” in the reproduced time band. Note that the belt-like reproduced image 224 has translucency, and the volume level display of the reproduced part can be confirmed.

As described above, the music composition display image 212 indicates the volume level of the three frequency bands for each beat by the color difference, so that the operator can intuitively grasp the composition of the music. For example, the portion indicated by reference numeral 228 in FIG. 18 is a climax portion of the music because the volume level is continuously “high” in all the frequency bands “Hi”, “Mid”, and “Low”. I can guess.

As shown in FIGS. 18 and 19, the effect image 211 functions as an operation unit for giving to the music being played. The effect image 211 includes a plurality of effect icons 225 indicating the types of effects that can be given to the music being played, a selected effect icon 226 that displays the type of effect being selected, and a trash can icon for deleting the placed effect. 227.

The effect types indicated by the effect icons 225 are “DELAY (output delay sound)”, “GATE (cuts input sound lower than the threshold level)”, “ROLL (repeats input sound)”, “FLANGER ( “Flanger effect”), “PAN (shaking the output sound left and right)”, “FILTER (changing the filter frequency)”, “REVERB (giving the reverberation effect)”, and “ECHO (while attenuating the delay sound) Output) ”. In addition, other effects such as “PHASER (giving phaser effect)” and “TRANS (cutting output sound in accordance with the beat)” may be arranged. In the effect image 211, it is preferable that the operator can set the type and arrangement of the effect icons 225 displayed in a circular pattern.

As shown in FIG. 19, the operator selects a desired effect icon 225,
By arranging the music composition display image 212 at a desired position, an effect operation can be performed. In the present embodiment, a desired effect icon 225 is arranged by dragging and dropping. Although illustration is omitted, before the effect icon 225 is pasted directly on the music composition display image 212, the effect icon 225 is actually placed in the center area (the area where the selected effect icon 226 is displayed in the figure). Drag and drop to set effect parameters (time, level). For example, the time parameter is set by sliding the center area in the horizontal direction, and the LEVEL / DEPTH parameter is set by sliding the center area in the vertical direction. In the present embodiment, a plurality of effect icons 225 can be arranged in one divided area. Further, by dragging and dropping the arranged effect icon 225 to the trash can icon 227, the once arranged effect icon 225 can be deleted. Thereafter, the effect arrangement can be corrected by rearranging different effect icons 225. In accordance with the arrangement of the effect icons 225 on the music composition display image 212, the player 10 performs a predetermined effect process on a portion corresponding to a predetermined frequency band in a predetermined time band of the music and reproduces the music.

Thereby, the operator can perform a desired effect operation after intuitively grasping the composition of the music piece before or during the reproduction of the music piece. For example, it is possible to grasp a portion where the volume level of music is high and apply a desired effect, or apply an effect suitable for the frequency band to the frequency band. In addition, since the effect operation can be performed by a simple operation of arranging the effect icon 225, it is convenient when performing improvisational acoustic performance during music reproduction. In general, the display width (the vertical width in the drawing) indicating the frequency band where the effect is frequently applied may be increased to increase the area of the corresponding divided region. Thereby, the area which arrange | positions the effect icon 225 can be increased.

FIG. 20 shows a case where a part of the music composition display image 212 (normal music feature value display) on the main display unit 210 is displayed in an enlarged manner (enlarged music feature value display). As shown in FIG. 5A, pinch out an arbitrary position (becomes the reference position 235) of the music composition display image 212 (touching with two fingers on the screen and performing an operation of spreading) Then, an enlarged display image 213 is displayed on the image. The enlarged display image 213 has a length corresponding to one beat before and after the beat of the reference position 235, and the area of each divided region is displayed larger than that of the music composition display image 212. As shown in FIG. 5B, an effect icon 225 can be arranged in a divided area on the enlarged configuration image 212. As shown in FIG. 10C, the enlarged display image 213 can be moved on the music composition display image 212 by dragging. In this way, an arbitrary position of the music can be enlarged and displayed. Note that the enlarged display image 213 may be erased after a certain period of time, or may be forcibly erased by touching with two fingers on the pinch-in screen and performing a pinching operation.

Note that a dedicated button for displaying the enlarged display image 213 outside the music composition display image 212 may be provided. Further, the enlarged display image 213 may be displayed outside the music composition display image 212 so that the display content of the enlarged display image 213 can be scrolled.

According to the enlarged display image 213, each divided area is displayed in a large size, which is convenient when the music is fast tempo or when a plurality of effect icons 225 are to be arranged in one divided area. Note that the effect icon 225 can be arranged on the enlarged display image 213 as described above, and the same type of effect icon 225 arranged on the enlarged display image 213 is arranged at the same position on the music composition display image 212. Is done.

Actually, when displaying a music piece having a general length of several minutes, as shown in FIG. 21A, a divided area corresponding to one beat has a very narrow display area. Therefore, when the effect icon 225 is arranged, it is better to automatically apply the effect in units of measures. That is, as shown in FIG. 5B, the region to which the effect is applied is automatically corrected based on the arrangement of the effect icons 225 that are roughly arranged. Thereby, even if the effect icon 225 is roughly arranged in a narrow divided area, an appropriate effect play can be performed.

For example, in a situation where DJs need to place effects in a short time, after confirming the composition of the entire song, even if the effects are placed roughly, for the time being, the timing of the effects will not be shifted and the sounds will be safely compiled. Can do. In other words, if there is enough time for effect placement, you can fine-tune and fine-tune it further, but if you place the effect roughly and there is no time, even if the placement is slightly shifted, the effect timing will not shift It is effective for the purpose. Although the auto-corrected effect range is a safe sound output, if the DJ wants to change the effect application range delicately, pinch out the position to change the music composition display image 212, and the effect icon 225 Can be finely adjusted by placing and dragging and dropping to the trash can icon 227.

According to the player 10 and the playback stem SY provided with the player 10, operability is improved by displaying the playback state (playback beat position) on the jog dial 12 which is the operation unit, and the operation shifts to an arbitrary beat. Even beginners can easily perform advanced operations such as scratches that require a variety of sounds and scratches that require rhythm keeping. The main display unit 210 can improvise effects while grasping the composition of the music. Therefore, unique acoustic performance can be easily performed by combining effect operation, scratch operation, and other operations.

In the present embodiment, the jog dial display unit 220 has the same area as the jog dial main body 12a arranged concentrically and the operation unit for performing the operation for adjusting the playback speed (scratch operation). However, the jog dial display unit The size of 220 may be smaller than the jog dial main body 12a serving as an operator. Further, this operator may be arranged in another area. In addition, the operation element for performing the scratch operation may be a separate device from the player 10.

[Second Embodiment]
Hereinafter, another embodiment of the present invention will be described with reference to FIGS. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

FIG. 22 is a plan view of the player 10 of the present embodiment. As illustrated, the player 10 of this embodiment includes a mode switching knob 300 that switches the display mode of the jog dial display unit 220. The mode switching knob 300 includes a display mode of the jog dial display unit 220, a first play mode (scratch operation, beat position display) for displaying a playback state by a playback position image 251, a beat position image 252, and the like, a playback position image 251, In addition to the display of the playback state such as the beat position image 252, the second play mode (effect setting, music feature amount display and beat position display (superimposition) displays the composition of the music by the music composition display image 212 of the music being played, etc. Display)) and the third play mode (scratch operation, music feature amount display and beat position display (superimposition display)). The jog dial 12 is rotatable in the first play mode and the third play mode, and the rotation is locked in consideration of operability in the second play mode. In this embodiment, the first play mode (normal mode) in normal scratch operation, the second play mode (effect setting mode) specialized for effect setting and arrangement, and both the set effect and scratch operation are effective. An embodiment is shown in which the 3 play mode (effect & scratch mode) can be switched by the mode switching knob 300. In the second play mode (effect setting mode) specialized for effect setting and arrangement, the display of the playback state such as the playback position image 251 and the beat position image 252 is omitted, and the music composition display image of the music being played back Only the composition of the music may be displayed by 212 or the like. Moreover, you may set so that other play modes can be switched.

FIG. 22 shows a state where the display mode of the jog dial display unit 220 is switched to the first play mode. In this case, the jog dial 12 performs display similar to that in the first embodiment, and the same operation is possible.

FIG. 23 shows a state where the display mode of the jog dial display unit 220 is switched to the second play mode (effect setting mode). As shown in the figure, in this mode, the jog dial display unit 220 displays a ring music composition in addition to the playback position image 251, the eight beat position images 252, the played back image 253, and the jacket image 254 of the playlist being played back. A display image 212 and an effect image 211 arranged in the center portion surrounded by the music composition display image 212 are displayed. The music composition display image 212 is obtained by deforming the belt-shaped music composition display image 212 in the first embodiment into a ring shape. That is, three frequency bands are indicated by annular regions having different inner diameters, and each beat position is indicated by a line image extending radially from the center, and divided by a time band divided by the frequency band and the beat position. The divided areas are displayed as a plurality of fan-shaped areas. In the present embodiment, in the annular music composition display image 212, frequency bands are arranged in the order of “Hi”, “Mid”, and “Low” from the outside. As in the first embodiment, a plurality of fan-shaped divided areas are displayed in different colors depending on the volume level, assuming that one area is obtained by dividing the time band indicating one beat by the above frequency band. Yes. Further, the music composition display image 212 displays a band-like reproduced image 224 displayed along the shape of the music composition display image 212 starting from a position of 180 degrees when the lower end of the display area is set to 0 degrees. Note that the width in the radial direction that divides each frequency band may be changed according to each frequency band. For example, the radial length of the divided area on the inner circumference side of the music composition display image 212 may be set to be longer than the radial length of the divided area on the outer circumference side of the music composition display image 212. According to this, the area of the divided area on the inner peripheral side and the divided area on the outer peripheral side can be kept uniform to some extent. Also, the beat position display 252 and the reproduction position display 251 are displayed in an overlapping manner.

The operator selects a desired effect icon 225 from the effect image 211 displayed in the center of the jog dial display unit 220, drags it to the center area, and adjusts the effect parameters by turning the time knob and the level depth knob. The effect icon 225 is arranged on the annular music composition display image 212 in which the effect icon 225 is arranged in the frequency band area. In this mode, the rotation operation of the jog dial body 12a (locking the rotation of the jog dial body 12a) and the stop operation are invalid.
