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.Basically, I’ve tried a number of different exponential and power curves but can’t get one that has the long, low slope on the low end. 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. And no, I don’t to just stick a log hsl in there :DAny help would be appreciated so I can get this out there and start using it!pos freq0.000 00.125 830.250 3620.375 4560.500 7680.625 17500.750 63000.875 127501.000 25000
