It’d be interesting to have outputs for each frequency separately, then feed them into a VCA mixer to mix them under voltage control. _Edit to add:_ I just realized since this thing generates square waves, could you use an analog switch as a VCA? Maybe not a [MAX313](https://lookmumnocomputer.discourse.group/t/kosmo-sequential-switch/1177) but maybe a DG412? Actually two. That’d give the same functionality but with voltage control, or at least I’m guessing it’d work. Others would know better. --- _[View the full topic](https://lookmumnocomputer.discourse.group/t/barton-4046-wave-shaper/1326)._
