<p>PURPOSE:To make easy and sure tone selection possible with a simple constitution by controlling turning-on and off of transistors by an intermusic detection signal and by short-circuiting a driving motor to generate a large damping power. CONSTITUTION:When an intermusic is detected, the output of intermusic detection circuit 2 is inverted to a high level, and transistors 3 and 4 are changed from turning-on and off states to turning-off and on states, and motor 6 is short-circuited. Therefore, motor 6 performs generator operations, and a large damping power is applied to motor 6 through on-state transistor of a large load, so that a damping mechanism and a solenoid, etc., to this mechanism are not required.</p> |
