DIY Synthesizer Demo

via MusicMiK:

This is a little demonstration of my DIY synthesizer. Due to video length limits, just a very very small subset of the features is shown.

The synthesizer provides 2 VCOs, 2 12dB state variable filters, ring modulator, noise and an extremely flexible routing system with 26 VCAs to get everything together. It consists of about 1300 parts and is completely built onto veroboards.

Update: not yet completed, but at least an insight into this synth: http://www.mik-music.org/MiK-one_Service_Manual_PREVIEW.pdf
