Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a mixer with a multi-track recorder in which a mixer, a multi-track recorder and the like are combined, and facilitates operations for realizing various work modes. .

[Conventional technology]

The recorder-equipped mixer realizes various work modes such as mixing, editing, and reverberation by combining the mixer and the recorder. In the conventional mixer with a recorder, the user connects the mixer and the recorder for each channel according to the work mode to be realized. For example, when recording an input signal, as shown in FIG. 2A, the switch 10 of each channel is connected to the contact 10a and the input signal is recorded on the recorder 14 via the mixer 12. During mixdown, as shown in FIG. 2 (b), the switch 10 of each channel is connected to the contact 10b to reproduce the sounds recorded on the plurality of tracks of the recorder 14 and to mix them with the mixer 12. Then, it is converted into a 2-channel stereo signal and output.

[Problems to be Solved by the Invention]

As described above, in the conventional mixer with a recorder, even if the connection state between the mixer and the recorder is decided depending on the work mode, the switch of each channel must be operated individually, and the operation is troublesome. If the user is not familiar with the operation, it causes confusion, and if the operation is mistaken, the desired work form cannot be realized. Especially, when the mixer has a plurality of mixing functions and a multi-track recorder is combined with the mixing functions, the difficulty is further increased.

The present invention solves the problems in the conventional technique and facilitates operations for realizing various work modes.

[Means for solving the problem]

The present invention provides a mixer having a plurality of mixing functions, a recorder having multi-channel tracks and capable of simultaneously recording while reproducing a recorded track while synchronizing timing of a new input signal to another track, and at least an unrecorded recorder. First recording on a medium or after erasing, recording a new input signal to another track while playing back and monitoring the recorded track, and mixing the recorded track as it is or with a new input signal. Various work modes, including the work of recording and recording on another track, partially re-recording the recorded track in a certain section, and the work of outputting the signal recorded on the recorded track as it is or by mixing it. To select a work form selecting means, and to realize the function according to the selection operation of the work form selecting means A connection control means for setting a connection state of the mixer and the recorder required automatically, and a display means for sequentially instructing a parameter of the mixer and recorder to be set in order to implement the selected function,
Parameter setting operation means for setting parameters according to the instruction of the display means is provided.

[Work]

Depending on the work form, there are cases where there is only a fixed connection state. Therefore, as in the present invention, the work form selecting means selects a work form, and the connection state of the mixer and the recorder for realizing the work form is connected. By automatically setting by the control means, the work is facilitated and erroneous operation can be prevented. Further, the parameter to be set can be easily set and operated according to the instruction of the display means.

The tape recorder 30 is configured as, for example, a fixed head type digital audio tape recorder, and is configured to record and reproduce digital audio signals on tracks of 8 channels simultaneously and independently.

The input mixer 32 is prepared for each channel, and individually and independently performs signal processing (equalizing effect addition, fading, panpot, etc.) on each channel input signal (digital signal) and outputs the signal to an arbitrary channel. As a result, the various work modes described above are realized. Input signals to the input mixer 32 are external input signals (performance signals, etc.) IN
Alternatively, a switch SW1 for selecting one of the tape reproduction signals PB is provided so as to be independently selectable for each channel.

The crossfader 34 is in edit mode (PUNCH IN, EDI
Cross fade is applied to (T) so that the sound connection at the edit start point and the end point does not become discontinuous.

Each channel output signal of the cross fade 34 is input to each channel input of the tape recorder 30.

The C / R mixer 36 has a work mode key 20 and a C / R monitor selection key.
The left and right two-channel signals to be supplied to the monitor in the control room in which this mixer with a multi-track recorder is installed are created according to the selection contents of 29. The switch SW2 is prepared for each channel, and it is possible to select either the tape reproduction signal PB or the input signal PGM to the tape recorder 30 for each channel. The output of the switch SW2 is subjected to signal processing such as fading and panpot for each channel, and then mixed into two channels, which are input to the switch SW3. The switch SW3 selects either the output C / 8 of the switch SW2 or the output CUE of the CUE mixer 38 and outputs it as a control room monitor.

The CUE mixer 38 has a work mode key 20 and a CUE monitor selection key 29.
The left and right two-channel signals to be supplied to the monitor for the performer in the studio are created according to the operation contents of.
