Making your own synth is a fairly tall order for most of us, but this new PCB from Polykit features all the elements you need to make your own monophonic or polyphonic synth! It features a single VCO with triangle, saw and pulse waveforms, with a ADSR, multiple VCAs, and a pole mixing multi-mode filter with 8 filter responses.
It also has inputs for PWM, FM and synchronization - as well as an external audio input. It seems like a very affordable way to start building your own synth.
