about

These are raw recordings of my new eurorack system. The boards' layout and panels were designed by me. All of the modules were based on quite standard designs: diode ladder VCFs, CEM VCOs, OTA VCAs, basic LFOs, discrete envelopes and single PT2 delay.
CV was generated by Korg SQ1 and Instruo's Harmonaig.

I kept modules quite simple, as the system was made specifically for future workshops and DIY kits (soon available via etsy shop)

The system will be keep growing in new modules!
