I will be writing a lot more about this machine. but quickly for those who cant wait a couple of days! this is what i did.
the 100k position has changed. its gone to the other leg of the transistor! makes it act a bit more like a normal oscillator without an offset. then added in this image is the best super simple filter i found to work with this specific oscillator. you can add to both the pitch knob and the filter knob vactrols easy!!! check my filters easy peasy lemon squeezy episode on that!!!
if you want to control the pitch of a few of these osc at once then youll need something a tiny tiny little more fancy because of the increased current. and light dependent resistors dont cope. more on that to come!!!
