well i can’t believe that on a modular synthesizer forum no one chimed in with Maths. and yes, indeed, function generation, attenuversion, constant voltages.
anyway I think we’ve got the main suspects on the table. personally, I haven’t used my Batumi or Stages with W/, but ymmv, it’s your build. In general I recommend Cold Mac, but it hasn’t been partnering with W/, without Shades.
