PURPOSE:To reduce a memory capacity and make it possible to correct an arbitrary part of operation data, by recording and reading operator data by a signal which is recorded on the additional track of a tape. CONSTITUTION:The reproduced play sound of tape deck 8 has the sound volume controlled according to operation data of operator group 1 through VCA group 10 by the command of CPU 5, and simultaneously, operation data is sampled synchronously with the digital signal, which is recorded on the additional track of the tape and indicates the sampling time, and is stored in RAM 6. Next, operation data of RAM 6 is read, and the control signal of VCA 10 is obtained after D/A conversion in 9, and the play sound of the same sound volume change as that for manual operation of operators can be obtained from output terminal group 11. |
