PURPOSE:To enable a player to easily operate parameter call switches by arranging the parameter call switches nearby respective musical sound control information setting switch group and making the relation between the switch groups and parameter call switches easy to understand. CONSTITUTION:The key code of a pressed key is inputted to a register KC and the state of a touch control flag TOUCH(K) is decided. Musical sound control is not performed with touch data when the flag is '0', but performed with key velocity data when '1'. Therefore, the touch control flag TOUCH(K) is 1, the key velocity data is inputted to a key velocity register KONV and when the flag TOUCH(K) is 0, a constant PKV is inputted to the register KONV. Then, a key-ON signal and data in the registers KC and KONV are outputted to tone generators TG(K) respectively and returned. At this stage, a sound system 15 outputs a musical sound. |
