**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](https://lookmumnocomputer.discourse.group/t/hero-and-sidekick-vcos/5179) for 3340 schematics with scaled and centered outputs and sine shaping.
