Abstract
PURPOSE: To obtain coupler sounds by independent musical tones by changing key touch information to another key touch information and assigning both informations to different channels of a sound production assignment circuit thereby forming the musical tones.
CONSTITUTION: Key codes KC outputted by a key coder 2 in correspondence to touched keys of a keyboard part are assigned to the specified channels of a key code memory circuit 6 via gate circuit 5 of a channel processor 4. On the other hand, the discrimination signal of upper and lower keyboards from the key coder 2 is applied to a conversion circuit 3. When the touched key is on the lower keyboard and a switch 20 is held closed, an AND gate 19 opens and the AND output of an OR gate 18 inverts to the same output as that when the upper keyboard was touched, thus the circuit 5 is controlled of its opening according to the actually key- touched lower keyboard and the upper keyboard corresponding thereto via the assignment control circuit 21 of the processor 4.
