1 is a diagram schematically illustrating a system to which a rhythm pad and a half cycle interlocking with the rhythm pad according to an embodiment are applied.

As shown in Fig. 1, the system of one embodiment converts the rhythm pad 100 for improvised accompaniment by the user when accompaniment is performed and the user accompaniment to accompaniment-based notes when improvised accompaniment is performed to reproduce the sound bank from the sound source. It includes a half-cycle 200.

When the pad part is hit by a user, for example, a person singing a song or a person around it, the rhythm pad 100 generates a corresponding MIDI note from the hit and transmits a signal in a half cycle to become a user performance. Thus, when the rhythm pad 100 becomes accompaniment through a song accompaniment, it generates a sound according to at least one instrument/effect sound type from the pad unit, and simply uses the pad to create a real instrument, for example, a tembourine or'wa'. It becomes the user accompaniment instead of the sound effect of. To this end, when accompaniment is performed by the accompaniment, the rhythm pad 100 provides the user accompaniment from the pad unit corresponding to at least one type of instrument/effect sound in the accompaniment according to the hit of the pad unit, thereby providing a real musical instrument through the pad. Instead, user accompaniment takes place. In this case, the signal is transmitted, for example, from the preset BLE (Bluetooth Low Energy) MIDI standard when information according to the user's performance is transmitted, the MIDI note of the rhythm pad 100 as a transmission of a corresponding wireless signal or a wired signal. Thus, user accompaniment is delivered. At this time, the BLE MIDI standard corresponds to the MIDI note each time it is hit by a communication format set in advance according to the wireless transmission corresponding to the transmission of MIDI information between the rhythm pad and the accompaniment information when a MIDI note is transmitted and conversion to accompaniment information. This is done by transmitting it as a wireless signal.

When the accompaniment 200 becomes a user accompaniment by the rhythm pad 100, the accompaniment of the user is converted into an accompaniment-based accompaniment and a sound bank is reproduced from a sound source, thereby providing accompaniment music of a song according to the user's improvised accompaniment. To explain this conceptually, in this case, the accompaniment 200 is, for example, when the accompaniment music of one embodiment is provided, the BLE analyzes the MIDI note of the user accompaniment, and the CPU transmits the corresponding half-cycle MIDI signal to the sound source. This is to play the sound bank from the sound source. At this time, the accompaniment 200 receives MIDI notes from BLE USB receivers provided to recognize accompaniment information of MIDI notes in BLE when such accompaniment music is provided, so that the MIDI notes are smoothly delivered in real time. . Thus, the accompaniment 200 plays music through a file built in the storage device, but when an external device, a rhythm pad, is connected, the accompaniment 200 additionally transmits MIDI information to the drum in the sound source and Sound effects, etc. are played. Therefore, when singing, the song accompaniment generates new contents in the form of improvised accompaniment from the fixed karaoke accompaniment music, and instantly creates the atmosphere of the song in accordance with the excitement of the singer. Therefore, if the existing accompaniment had a passive form of singing only a song, the rhythm pad accompaniment according to an embodiment is a method in which the singer directly intervenes in music as well as song.

In this case, the rhythm pad 100 according to an embodiment sets the MIDI signal of the half cycle corresponding to each MIDI code to be converted from the half cycle when the MIDI code is hit according to the user accompaniment, so that the user accompaniment becomes an accompaniment-based coin. will be.

When the pad operation unit is accompanied by the accompaniment, the user accompaniment is provided as the accompaniment from the pad unit corresponding to at least one type of instrument/effect sound as the accompaniment according to the hit of the pad unit, so that the user accompaniment is replaced by the actual instrument through the pad. Make it possible. In this case, the pad operation unit provides a user accompaniment from each pad unit corresponding to a number of different musical instruments and sound effects, for example, so that a number of different user accompaniments are provided. For example, when the user sings a song, the user provides a tembourine sound as a half cycle according to the hitting of the corresponding pad, or the response sound of people around'wa' is provided as a half cycle according to the hit of the corresponding pad. It becomes a variety of user accompaniment.

When a user accompaniment strikes, the note generator generates a MIDI chord from a preset format that generates a MIDI chord from the user accompaniment strike as a different sound level according to the striking intensity according to the corresponding instrument/effect sound type to become the user accompaniment.

When a MIDI code is generated according to a user accompaniment by the note generator, the signal transmission unit transmits the MIDI code in a pre-registered half cycle according to a communication protocol format set in advance with the half cycle, thereby providing a user accompaniment to the half cycle. In this case, the communication protocol format is, for example, the aforementioned BLE MIDI standard or wired communication protocol format.

MIDI notes provide notes for each instrument/effect sound type from a preset format so that when a rhythm pad is hit, MIDI chords are generated with the sound level of the corresponding instrument/effect sound type and striking intensity for a number of different pads. A note is provided.
