I used block diagrams and the Minimoog Service Manual to build the dsp chain. What I have now can give a *reasonably* accurate rendition of Minimoog patches from sheets found online (ELP Aquatarkus, for instance). What I did notice in comparing it to the Arturia Mini V AudioUnit minimoog simulation, is that the knob curves for frequency are different form what I’ve been able to do, so some patches aren’t quite *right* yet. </div><div

All of my curves rise too quickly. In any case, this is a curve fitting problem and this is the data I’m working with. The mapping I want is 0 - 1 to 20 0 20kHz.
