Firstman Multivox SQ-01 Analog Sequencer Synthesizer 1980

Uploaded on Feb 2, 2010 David Morley·20 videos

"This is my Firstman SQ01 sequencer and synth. Pretty rare unit and a VERY big sounding synth. MUCH more low end than a TB303 but not quite as squidgy! Was released before the 303 I believe (1980)
On speakers you will hear how deep the low end is when the resonance is not cranked. VERY dubby sounding. It also has CV-Gate in and out as well as clock in and out so can be used in a larger CV-gate setup or as a sequencer for any cv-gate synth. Two envelope settings and gate length plus a sustain (release) control."

"The Firstman SQ01, manufactured by Multivox, is said to pre-date the Roland TB-303 and has a deep analogue bass sound somewhere between the 303 and a Moog bass. The controls (left to right) are: Tempo, Release, Bar, Filter Cutoff Frequency, Filter Resonance, Oscillator Fine (tune) and Oscillator Frequency, Sustain and Power/Volume. Connections at the top rear are: DC12V in, CV in, Gate in, Clock in, Footswitch, Synchro out, CV out, Gate out, Clock out and Audio out. These connections really add to the fun-factor when hooking up with other analogue gear, or use a midi-cv converter to control it via midi.ONLY 200 OF THE SQ01 WERE MADE"

  1. So happy to find the schematics to this beaty.
    But is it possible to get a scheme that's more high resolution?

    Would be overwhelmingly happy if that's possible.

    Best / Daniel
