PURPOSE:To enable high effect to be obtained with respect to the localization of a cross fade processing circuit at the point of edition by providing a time difference to the cross fade start time of the cross fade processing circuit. CONSTITUTION:The counter output of an address counter 16 assigns the addresses of ROMs 14, 15 at any time, and the contents of the address-assigned ROMs 14, 15 are digitally outputted and become the inputs for one of digital multipliers 12, 13. Here, face effect is provided to the outputs of the ROMs 14, 15. The master input 19 and slave input 20 are faded with the outputs of the ROMs 14, 15 respectively by the multipliers 12, 13, and the two outputs are added 17, and the added signal is supplied as a cross fade signal to a slave deck and is thereby recorded. On the other hand, with respect to CH2, if the lapse of time by DELTAT from the cross fade starting time of CH1 is detected with an address code, a cross fade control command is inputted to the cross fade processing circuit 22 of CH2 by a CPU26, and the operation similar to that for CH1 takes place. |
