Apparatus for converting the relatively rapid rise time, relatively long fall time tone envelopes of a music source output to envelopes having relatively long rise time and relatively rapid fall time includes a sawtooth relaxation oscillator whose output feeds a modulator which is also fed by the music source. The oscillator is turned on via a transistor switch when the average power of the signal at the output of the modulator exceeds a predetermined reference threshold signal.
