A waveshaper design for the AS3340

Hey all!!

I have been thinkering with an AS3340 to turn it into a waveshaping VCO for eurorack.
It’s a bit basic of a design, but non the less might be intresting for some of you. The simulations inputs are acurate to the IC-s output.

Hope you will find it helpful on your synth journey!

That’s a link to a file on your own computer, which is not going to be of use to others.

Interesting, see also Hero and Sidekick VCOs for 3340 schematics with scaled and centered outputs and sine shaping.
