 For example, VCO 1 can output a square wave through VCF 1 whilst also outputting a high-pass filtered sawtooth wave through VCO 2.Another example is that the envelope generators can be assigned to any of the VCO, VCF and VCA modules and can also be inverted.Because the LFO is voltage controlled, the oscillating speed can be governed by an envelope generator and different waveforms can be applied to the other modules all at the same time.
