The filter details here seem very detailed, thanks so much 8bitbubsy for the precise description for implementation! (for interest, this parallel discussion on emulating the filters also has some images of two of the filter shapes)

So the remaining big issue is how detailed I could get with modelling sample frequency and aliasing. I hoped to use the Doepfer device to introduce aliasing and just play with it (given the varying interaction between eg. the individual sample rate of a sample in Octamed, and the sample rate of Paula playing it out), but I wonder if there is a precise way to think about/model this?

If you have the patience to unpack it a bit - Are there subtle variations in the overall sample rate depending on final output volume?
