Quick Overview


The Werkstatt-Ø1: Moogfest 2014 Kit is a patchable and compact, one oscillator analog synthesizer. It was originally created as a kit, to be the foundation for exclusive “Engineering VIP” workshops at Moogfest 2014. Due to a number of requests, Moog is offering a no-soldering-required version of the Werkstatt-Ø1: Moogfest 2014 Kit in limited quantities, at select US dealers only. Assembly is extremely simple: Any user can quickly build an analog synthesizer based on classic Moog circuits, and if desired, study the analog circuits. Werkstatt was created to be an educational tool, but it is also a formidable, compact analog synthesizer from Moog.


Werkstatt-Ø1 is 100% US made

Werkstatt CV Expander

The Werkstatt-01 CV Expander converts Werkstatt’s 20pin patchable expansion header to 12 grounded 3.5mm jacks. This allows your Werkstatt to easily interface with external CV-equipped analog gear.  


VCA: 0V to +5V in VCA EG Mode, +/-2.5V in VCA ON Mode 

VCF: -5V to +5

VCO LINEAR FM: +/-2.5V (This is an inverting control input) 

VCO EXPONENTIAL FM: -5V to +5V, 1V/Octave, trimmable 

LFO CV: - 5V to +5V (Negative CV slows LFO more than panel) 

VCF AUDIO: Unbuffered/Unmixed AC coupled input to VCF.



KB CV: Nominal 0.3V/semitone from 1 octave keyboard (Attenuate for 1V/Octave)

GATE: 0V (off) to +5V (on) gate signal generated from low note priority/ legato Keyboard circuit. (This jack may also be used as a GATE INPUT.)

EG: Simple ASD or AD type Envelope Generator, 0 to +5V signal 

LFO: -2.5 to +2.5V wave shape selected from LFO Wave Switch. 

VCF: -2V to +2 V signal for audio or CV uses.

VCO: 0V to +5V signal, shape selected by VCO Wave Slide Switch.
