The SID synth is working!
As I just bought a simple oscilloscope, wave shots follow..
The SID filter works by using two capacitors. I think it works by switching them on and off in sequence. However it works internally, you can experiment with the values of the capacitors. So to experiment without solder/desolder I put a pin header.
The filtered saw with lots of resonance
Now on to a casing.. I had some ideas. But I would like first to get my hands on something to realize it.. Patience is a virtue. I am no virtual, I am real (I think :)
