ahh, that’d make some sense! It looks like you do get a smoothed out waveform rather than hard square waves:
Here’s where I’m at with the Kicad design (Unrouted, no panel design yet either). It’s going to be in Eurorack format rather than Kosmo I’m afraid 
. I’m also planning on using 6x 555 timers because I bought a tube of the damn things a while ago and this seems like the perfect project to use some of them up…
