MFOS WP-20 Experimental Analog Synthesizer & 8 Step CV/Gate Sequencer

via this auction

See this post for a demo of one in a different case.

"WP-20 experimental analog synthesizer which also comes with a 8 step CV/Gate sequencer, along with N.American power supplies and two 1/8" cables for connecting the CV and Gate input/outputs together. Please check out the pictures of this unit as it has a very unique hand made look. The cases are aluminum with hand stamped labeling.

This is one wild unit, capable of much more than its humble specs indicate. It really shines in wild FM sounds, but can also play nice warm analog tones as well. But please be aware, if you are looking for a traditional synthesizer - keep looking! There is no MIDI and its VCO does not scale to V/Oct. Although it is certainly will play nice melodies using the 8 step sequencer you should not buy this thinking you are getting a Novation Bass Station, this is an 'experimental' synthesizer instead.

- VCO with square and triangle
- A VCF with resonance switchable
- Loopable A/R generator with a manual trigger button (can get into audio range in loop mode)
- LFO with saw/triangle and square waves (which can also get into audio range).

There are 1/8" inputs for CV (pitch) and Gate (to trigger A/R).

The 8 Step sequencer has, you guessed it - 8 steps. But you can switch between 2, 3, 4, 5, 6 or 8 steps via the "steps" knob. 1/8" outputs for CV and Gate as well as a 1/8" input for external clocks (but note - some of the clocks from my modular would trigger the WP-20, and others would not).

If you would like to hear some of what this machine is capable of, I recorded a 10 minute track using the WP-20 as the sole sound source along with the 8 track sequencer (I also ran the WP-20 through some effects pedals, including a Cimmerian Caves and a home made spring reverb - plus some VST effects). Listen Here:

It is an odd unit, certainly not perfect - but if you use its for its strengths (and not focus on its limitations) you can create some very interesting sounds. Lo-fi, warbly and weird is how I would describe it."
