MFOS 10-Step Sequencer

This is listed on this page, rather than the Modules page, because I spilled Crazy Glue on the back of the panel. Some of the components may be recoverable – and perhaps even the panel itself – but I can’t guarantee that. The MFOS board, together with all the components is, however, just fine!

The Saw Bench Synthesizer

A highly portable monosynth, with a 100% analog signal path. The kit cost about $125. Included here are the two circuit boards and all the parts are available somewhere in the parts package included in this sale but you’ll have to hunt them down.

To learn more about the Sawbench and to get detailed construction notes, go here.

  • Small and portable, yet very ergonomic. Focus on hands-on controls with good grouping and spacing.
  • A four-pole diode ladder VCF, with high resonance
  • Separate ADSR envelopes for VCA and VCF
  • LFO with 3 waveforms, plus a Sample & Hold, for VCF
  • Frequency Modulation for deep growling bass sounds
  • Manual controls such for Env and LFO enable, waveform selection, ADSR mode / LFO switching
  • MIDI controls of all digital features (envelopes, VCF cutoff, LFO, etc)
  • Legato, glide, looping ADSR (MIDI)

Where’s the Party At 8-bit Sampler

These boards are no longer available so I suppose this would be considered rare… read about the WTPA here:

and here.

Yusynth VCO & Yusynth Sample & Hold / Noise Sourc

Home-etched and undrilled PCBs. Resist is still on the traces. You just need to cut and drill. Read about the VCO here and about the sample & Hold here.

THOMAS HENRY 555 VCO

10 commercially manufactured PCBs, 4 of them have a few of the components installed (see photo). I can’t recall where these are from but I will try to track down more info about them.

See video of Fonik’s version of this excellent VCO to the right.
