A Minimoog based VCV Rack patch. It’s a surprisingly accurate emulation. I added a fourth oscillator to use as a modulation source. The modulation wheel is mapped to both the filter cutoff and the oscillator4/noise modulation amount. Only free modules are used.
The VCAs are (left to right, top to bottom):
External input volume,
Mod wheel cutoff modulation amount,
Key tracking amount,
Amount of contour (envelope depth),
Oscillator 1 volume,
Oscillator 2 volume,
Oscillator 3 volume,
Noise modulation amount,
Oscillator 4 modulation amount,
Mod wheel frequency and filter modulation amount,
and pitch bend amount.
The switches are (top to bottom):
Oscillator4/noise cutoff modulation,
Mod wheel cutoff modulation,
The upper Vult knob controls the amount of glide (portamento).
The upper two A/B switches switch between MIDI and external input for control of the filter and amplitude envelpoe gates.
Disconnected the pitch wheel.
Added toggles for oscillators 1, 2, and 3, frequency modulation, and filter modulation (in order).
Added an external input capable of feedback.
Added toggles for noise, external input, cutoff modulation with mod wheel, portamento, and key tracking.
Added switches for gate control.
Added a knob for portamento control.
Discovered moving the pitch wheel fixed the tuning issue, and reattached it.
Rearranged some modules.
This version has all the features of a Minimoog that I can think of, hence the 1.0.
Thanks to Lindenberg Research for releasing the excellent oscillator and filter designs used.
It’s set to a Catherine of Aragon lead.
