The Pollux MiMi-a Polyphonic Synthesizer Resource Page

Some of you might remember the rare Pollux MiMi-a Polyphonic Synthesizer from the demo video posted here and the Synth Gathering Sweden post here. The MiMi-a was a six voice analog polyphonic hardware synthesizer from Ricard Wanderlöf in 1987.

Swissdoc wrote in to let us know he found the resource page for the MiMi-a. According to that page: "The MiMi-a is a microprocessor controlled six-voice multitimbral analog MIDI synthesizer that I built (mostly) during the spring of 1987. That makes it ... wow ... over 20 years ago ...
Each voice is mostly analog; all signal processing is analog, with the envelope generators and LFO's being partly digital, as well as the oscillator front-ends. This makes for a warm analog sound while at the same time retaining digital precision for the envelope and LFO timing, and oscillator frequencies.

Each voice consists of:
Two oscillators, A and B, each with an adjustable range of six octaves, with sawtooth, pulse and square waveforms, as well as combinations of these, as well as two ring-modulator-type waveforms. Oscillator A can be hard-synced to oscillator B.
A combined sub-oscillator/noise generator (oscillator C).
A Moog-type -24dB/octave voltage controlled lowpass filter with voltage controlled resonance.
A linear/exponential VCA.
Three ADSSR envelope generators, one for the filter, one for the VCA and one assignable.
One syncable LFO."

See the resource page for additional details including pics of the inside and demos.


  1. Why is there no entry for this on Vintage Synth Explorer?

  2. I would think because it's a one-off DIY synth that never was in mass production.
