Cgs synth

Thanks Laurie.

I saw that I made an error, I put the trimpot resistors in wrong
places. I have already fixed this.

I have been able to calibrate the filter, but the potentiometer of
frequency only covers from 40 hz to 1Khz. If I increase the trimpot,
I lose low frequencies, for example I can obtain from 100 hz to 2Khz.

Is it normal ? Can I obtain a wider range of frequencies?

Also i have noticed noise when I turn the resonance pot.

Is it normal?



Many thanks and Best Regards
