Re: Let me hear your bright new ideas for future Doepfer A100 mod

2008-12-05 by Adam-V

I would have thought that, assuming the correct triangle amplitude was
applied, it shouldn't matter what the source of the waveform was. I
base this on a quick look at Tim's schematic and associate blurb and
am happy to be corrected if I am wrong.

Cheers,
Adam-V
