PURPOSE:To easily control a musical tone by setting arbitrarily a reference signal, comparing an operation detecting signal and the reference signal and outputting a signal for controlling the musical tone in accordance with a large/ small relation of both the signals. CONSTITUTION:An operation detecting signal Sa which is varied in accordance with an operation of a part of the body of a man is outputted from an operation detecting sensor 10, and also, a reference signal Vref is outputted from a refer ence signal generating means 30, and a musical tone control signal output means 40 compares the operation detecting signal Sa and the reference signal Vref, and outputs a musical tone control signal for controlling a musical tone in accordance with a large/small relation of both the signals Sa, Vref. In this case, the reference signal generating means 30 is constituted so that the refer ence signal Vref can be set and changed, therefore, each person who executes a dance and rhythm gymnastic exercises can set arbitrarily a generation start time of a musical tone control signal corresponding to an operation of the body by setting this reference signal value to a desired value. In such a way, the musical tone can be controlled easily. |
