Thanks for all this, great stuff!

Know any more very very simple +/-12v VCOs, however 'bad' (ie I don't care at all about octave per volt)? I found a nice saw wave one [edit: oh it's one you posted here already] but some other shapes would be good too. Looking for the most minimal parts counts so I can build multiple oscillators in as small a space as possible :)

you can slap easy multiwave together out of 8038(minimum 10v power)

you can put caps on switch for VCO/LFO functions

this charlie slick 8038 LFO schematic has vanished from online... let me dig through my archives
8038 Multiwave VCO on chip
not sure of your current intent
yet it lowers your parts count
happily works +12/-12
saves design space

BTW you crank out multiple squarewave timer oscillators from hex inverter also

wow thanks will study these infos!
not sure of your current intent
me neither haha. I finally fixed the obvious dumb mistake in the MFOS wall wart power supply i built years ago to power a matrix mixer, so now i'm getting into some modular circuits just because I can :D want to build some very small system to interface with other gear. one or two bought eurorack modules and several DIY things. Mainly dictated by price, ease of build and small size :)

Looks great thanks. I already have a Chua's Chaos circuit built from an educational kit, definitely interested to explore more chaos circuits :)
