Vactrol Cross-fade Fun!

Just messing around with a vactrol crossfader on the breadboard and then controlling it from the silent way lfo. The bass sound is a system x oscillator and the other input channel is an FM sound which is a sys x Oscillator modulated by the sine wave output from the yusynth osc. The output from the crossfader is then fed into 1 channel of the stereo Hearne Morley HM2040 filter (12db).
