Voltage Modular 2.9.x patch.

An attempt at a 3-op through zero FM synth.

The VCO is the modulator, the first zero oscillator a carrier/modulator, and the final zero oscillator is a carrier.

Both zero oscillators have velocity sensitive ADSR (though I haven’t used the Dyn controls) for the FM index.

The FM output goes through a standard chain of VCF and VCA, both sharing an ADSR.

The effects are provided by a Comb Filter with ADSR, a delay and a plate reverb.

Note the use of Bus1 for pitch CV and Bus 2 for gate.

Six variations provided.
