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 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):

Oscillator 1,

Oscillator 2,

Oscillator 3,

Noise,

External input,

Frequency modulation,

Oscillator4/noise cutoff modulation,

Mod wheel cutoff modulation,

Key tracking,

and portamento.

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.

Version 0.91:

Disconnected the pitch wheel.

Added toggles for oscillators 1, 2, and 3, frequency modulation, and filter modulation (in order).

Version 1.0:

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.

Enjoy!
