Below is a list of synth modules I made so far, with link to blog articles where available. For some modules I designed proper PCB's, as indicated below. These PCBs and matching front panels are available for sale.
Audio sources
- VCO 3340 (PCB)
- Avalanche VCO (Stripboard layout)
- Sawtooth core VCO (part 1 and part 2)
Audio processing and effects
- Dual VCA (PCB)
- Transistor Ladder Filter (PCB)
- KS-20 Filter (PCB)
- Wavefolder (PCB)
- Discrete VCA
- Spring reverb
CV sources
- ASR Envelope (PCB)
- ADSR Envelope
- Variable waveshape LFO
- Voltage controlled slope generator
- Voltage controlled slope generator 2.0 (PCB)
- Brownian LFO
Utility modules
- Quad Attenuverter / Mixer (PCB)
- Dual 3-channel audio mixer
- Quantizer (PCB)
Workshop projects
These are step-by-step projects intended for beginners-style workshop.
