This new project (March 2019) will bring a lot of the elements of an analogue synthesiser into the small Eurorack format. First item to build will be the rack, initially it will be two rows 4U high by 84HP wide.

Ideas for my first Modules:

  • A +/-12V Power Supply with distribution.
  • Clock/Sequencer.
  • Voltage Controlled Oscillator(s).
  • Voltage Controlled Filter(s).
  • Envelope Generator(s).
  • Noise Generator.
  • Voltage Controlled Amplifier.
  • Echo Unit.
  • Low Frequency Oscillator.
  • Sample and Hold.
  • Mixer - Pan to Stereo.
  • Midi to CV/Trigger.
  • and...
The Rack

Built from offcuts from the Maplin 5600 case, the angled wood suited the Modular Synthesiser perfectly. It still needs sanding and varnishing. The Rack should hold a reasonable amount of 4U modules..

My first four boards are under way, the PSU, the VC Oscillator, the Mixer and Echo board. The PSU board and Echo Module are based on circuits from Practical Electronics and modified to suit my needs. The Mixer Module is taken from my 9+24 channel mixer and the VC Oscillator is based on the CEM3340 data sheet and again modified to suit my needs.
