Features
- Four channels of seperate/mixed VCAs
- Attenuators for CV modulation
- Sliders for adjusting volume
- Internal normalisation: if channel output not plugged in, automatically mixes signal into channel 4 out (mix out), the module can be used as four seperate VCAs and a four channel VC mixer and everything in between
Quirks and Problems
- Mostly works fine, some channels overdrive sometimes, some channel leaks sound when volume is fully down, mixer chip (TL072) becomes hot (IDK if that's normal)
- sliders are logarithmic, but I can't notice it during use.
