One of the latest projects:
Besides all the standard work most synths receive, it also got these mods:
Analog ring modulator (to external input's normal)
Range switch for LFO. Normal or high freq (to 7Khz!)
Auto-trigger switch for LFO to Envs.
Env LEDs colors changed and their brightness now controlled by their actual envelopes.
Env 1 CV to VCO modulation control added.
Various cosmetic changes.
