"Custom made, Musi analog modular synthesizer modules with a Paia/Frack 19" rackmount case and custom +/-15V power supply with Blacet style connectors.

Runs on AC 120V mains, comes with power cable. Fully callibrated and tested, VCOs have temperature compensation but with all analog gear its most stable after letting it warm up for 15 mins.

Rack includes:
3x VCO 1, modules
2x VCA 1, modules (stereo VCA and includes ADSR+1 envelope)
1x PSU 1, internal power supply

The modules are compatable with Paia/Blacet sized racks, and use standard 3.5mm audio jacks.

VCO 1 Module Details:
-------------------
Inputs:
1Volt / Octave CV IN, Basic control voltage input, knobs for rough base pitch and fine base pitch.
FM1 IN, Frequency Modulation with input level knob.
FM2 IN, Frequency Modulation with input level knob, 2x input scaling.
Pulse Width IN, Pulse Wave Width Modulation with input level knob.
Sync IN, Synchronize waveform start input.

Outputs:
Saw OUT, select saw or ramp waveform out.
Pulse OUT, Pulse waveform output, knob for base pulsewidth.
Tri OUT, Triangle waveform output.
Shape OUT, Diode waveshaper output, select Saw/Ramp/Triangle input, two shape knobs shape positive or negative part of the waveform.

Frequency Range: Near zero LFO to well over 25Khtz
Temperature compensated
Onboard votage regulation, works with +/-12V power supplies as well as +/-15V
Ultraviolet Purple waveform display LED.

VCA 1 Module Details:
-------------------
Inputs:
Stereo Signal IN, Stereo audio signal input, knob for base VCA gain.
VCA CV1 IN, VCA control voltage input with input level knob.
VCA CV2 IN, VCA control voltage input with input level knob.
Trigger IN, ADSR triger control voltage input.
Gate IN, ADSR gate control voltage input.
Insert IN, extra envelope insert level trigger.

Outputs:
Stereo Signal OUT, Stereo audio signal VCA output.
ENV OUT, Envelope waveform output.

Switch:
ENV to VCA - links internal envelope generator to audio VCA, otherwise stereo VCA runs independent of ADSR+1
Knobs for Attack time, Decay time, Sustain level, Release time, Insert level, Insert time.
Also uses onboard voltage regulation.

PSU 1 Details:
-------------------
AC120V input, fused, +/-15V output
6 Blacet/MOTM style power connectors."
