After the execution, the CPU 150 exits this track recording subroutine and returns to the execution of the main flow.

Mixing Edit Mode In the mixing edit mode, the performance signals for each part selectively recorded in each of the track memories 200 ₁ to 200 _n of the multi-track recording memory card 20 are mixed down into two-channel stereo signals. This is the mode for editing. Further, in the mixing editing mode, the signal obtained by the editing is recorded in any _one of the bank memories 220 _{1 to} 220 ₃ of the multi-track recording memory card 20.

When the address and the bank number where the edited signal is to be recorded are specified, the CPU 150 shifts to the execution of a mixing edit subroutine as shown in FIG.

In FIG. 6, first, the CPU 150 takes in all of the track numbers designated as described above, the start address, and the bank number, and stores them in a predetermined area of the RAM 108 (step S31). Next, CPU
150 determines whether or not an editing start command has been issued from the operating device 110 until this editing start command is issued (step S32). Here, the user operates the operating device 1
When an edit start command is issued by operating the number 10, the CP
The U150 supplies a monitor selection signal for monitoring and outputting the edit mixdown signal output from the equalizer circuit 103 to the selector 104 (step S33).
Next, the CPU 150 determines in step S31 that R
The bank number stored in the AM 108 is read, and the bank memory 220 (bank memory 2) corresponding to the bank number is read.
For one) of the 20 220 ₁ -220 _3, a bank clear signal should erase the memory content and sends it to the multi-track recording the memory card 20 via the control signal IF 106 (step S34). By executing the step S34, all the stored contents of only the bank memories corresponding to the bank numbers designated as described above are erased from among the bank memories 220 _{1 to} 220 ₃ . Next, the CPU 150 sends, to the bank memory 220 corresponding to this bank number, a bank write command signal for requesting the start of recording, by the control signal IF.
The data is sent to the multi-track recording memory card 20 via the communication 106 (step S35). By executing step S35, only the bank memory 220 corresponding to the bank number designated as described above among the bank memories 220 _{1 to} 220 ₃ starts writing the edit mixdown signal. Next, the CPU 150 reads the start address and the track number stored in the RAM 108 in step S31, respectively. Here, the CPU 150 selects _{one of the} track memories 2001 to 200 _n formed on the multi-track recording memory card 20 for the track memory corresponding to each of the designated track numbers as described above.
A track read command requesting that playback be started from the position of the start address is sent to the multi-track recording memory card 20 via the control signal IF106 (step S).
36). By the execution of step S36, the performance signals stored in each of the track memories requested to be edited are simultaneously read out of the track memories 200 ₁ to 200 _n , and the mixer circuits 1 of the mixing and editing apparatus 10 are respectively read out.

0 and the speaker 70 outputs sound. The user performs various volume adjustments, pan adjustments, effect adjustments, and equalization adjustments for each track by operating various knobs provided on the operation device 110 while monitoring the sound output. At this time, the operation device 110
An operation signal corresponding to each of the editing adjustment values for each of these adjustment items is sent to the CPU 150.

After the execution of step S36, the CPU 15
A value of 0 determines whether such an operation signal has been supplied from the operation device 110 (step S37). If it is determined in step S37 that the operation signal has been supplied from the operation device 110, the CPU 150 outputs a volume control signal, a pan control signal, an effect control signal, and an equalizing control signal of the edit adjustment value indicated by the operation signal. The signal is supplied to the mixer circuit 101, the effector 102, and the equalizer circuit 103 (step S38). At this time, an edit mixdown signal reflecting the editing operation in steps S37 and S38 is output while being monitored.
The data is written into one designated bank memory as described above. Next, the CPU 150 sequentially records the edit adjustment values in the edit adjustment value recording area of the hard disk device 107 in association with the card identification number stored in the RAM 108 in the above-described initialization subroutine (step S1). S39). The editing adjustment values recorded in the editing adjustment value recording area are stored in the initial setting subroutine shown in FIG.

After the end of step S39 or when it is determined in step S37 that no operation signal has been supplied from the operation device 110, the CPU 150
It is determined whether all the performance signals stored in each track memory have been read (step S40). If it is determined in step S40 that all data has not been read, the CPU 150 proceeds to step S3.
7, the operation as described above is repeatedly executed.
On the other hand, if it is determined in step S40 that the read operation has been completed, the CPU 150 outputs a control signal to the bank memory and the track memory to terminate the write and read operations to the control signal. IF
The data is transmitted to the multi-track recording memory card 20 via the communication 106 (step S41). After the execution of step S41, the CPU 150 exits the mixing edit subroutine and returns to the execution of the main flow.

Bank reproduction mode The bank reproduction mode is a mode for reproducing and outputting an edit mixdown signal recorded in each of the bank memories of the multi-track recording memory card 20. During execution of the main flow, the user operates the operation device 110 to select execution of the bank reproduction mode. Here, when a bank number to be reproduced is designated, the CPU 1

In FIG. 7, the CPU 150 first takes in the bank number designated for reproduction as described above and
108 is stored in a predetermined area (step S51). Next, the CPU 150 determines whether or not a bank regeneration start command has been issued from the operating device 110 until this bank regeneration start command is issued (step S52). Here, when the user operates the operation device 110 to issue a bank reproduction start instruction, the CPU 150 selects a monitor selection signal to output a mixdown signal read out from the multi-track recording memory card 20 by the selector 1.

The signal is converted into an analog signal via 5 and output to the monitor.
Next, the CPU 150 determines whether or not a bank regeneration end command has been issued from the operating device 110 until the bank regeneration termination command has been issued (step S55). Here, when the user issues a bank reproduction end command by operating the operation device 110, the CPU 150 sends an end signal requesting a reproduction stop to the multi-track recording memory card 20 via the control signal IF106. (Step S56). After execution of step S56, the CPU 150
Exits the bank regeneration subroutine and returns to the execution of the main flow.
