Elektor Formant Modular

I like your tune on your page.
I will look into the asm, but my main aim from this project is to 
understand why the synth works and how it was designed and how I can 
improve on it. Hence why I picked the Formant. I'm doing spice 
modelling on the formant just now and having issues with the VCO. 
The wave shaper works fine but my oscillator fails to start. I used 
my own CCO to calibrate the waveshaper just to confirm the design. 

I'll let you know how I'm getting on in about 3 weeks. Loads to do. 

Cheers mate
