Here comes the monster. That thing is up and running, and works quite well actually. Still a bit of work to do on it though. I need to find out how to properly scaled the 1v/oct input for the lower half of the module.
It looks like an old 60’s home-made rocket module but the expense for a PCB, for a one-off project, isn’t worth it.
the drum patterns are generated by the top half and we can also hear some nasty sound comming from the lower half.
I’ll try to find a way to export PDF for kicad if there’s any interest for someone to reproduce the module.
