Re: Freq Shifter

Jurgen's circuit is of interest, yes. However, I have a general rule: If there's over 10 analog ICs involved, who in the f@*k am I kidding. This has saved me from countless failed attempts to recreate circuits from my past in which I lust and why I stick to the easy stuff, like B

Peter, I'd be very interested in the mod you suggested. By the way, I've tried applying very low (as well as negative) voltage to the CV input, but have had no success. Bypassing the A126's internal oscillator might very well be the answer. Okay, I have to admit that basically I'

Don't know if it's possible (haven't seen a schemo) but thinking about the lowering the frequency range of the internal osc, I was thinking...why not just have an external input that bypassed the internal osc all together. This probably isn't possible. Not sure how the quadrature

Neither the A116 nor the A136 give you instant gratification. They both require plenty of thoughtful experimentation. This is what separates the synth programmers from the module shoppers. Once you've unlocked their secrets, consider it a badge of honor. Joe --- In Doepfer_a100@y
