Synthesizer Modules

I am steadily turning my synth ideas into reality. The result is, hopefully, a range of modules suitable for analogue modular synths, audio processing systems, analogue polysynths, etc.

All modules will be offered as bare PCBs intended for experienced builders to assemble.

• Voltage-controlled 4-stage all-pass filter module, which can be used as a stand-alone phaser, or chained with multiple modules for longer phaser-type audio processors.
• Voltage-controlled dual sine LFO, again based on the SSM2164 quad VCA.
• 3-pole 18dB/octave voltage-controlled state variable filter, based around an SSM2164 quad VCA.

Module Blocks

At the top right corner of each module's page is a clickable link to a block diagram of the module. Each section of the module has a heading, then a block showing the inputs on the left and the outputs on the right. Audio inputs and outputs are black text on a white background, CVs are white text on a black background. For example, the VCLFO with 2 blocks looks like this:
