Sure. I was just curious as to whether there was scope at a later to date to play with the DSP code. I've looked at the source again (cheers, David ;) and I can see what David means, in that for each device (Darla20, Darla24 etc) there is a block of data defined eg in Darla20DSP.c (in the DSP folder) which is the microcode to load into the DSP. So we don't need to mess about with that at this stage, if ever- TBH the hex doesn't look like code seqs to me (especially the Mia stuff) more like tables of setup info. Still, as you say, it's irrelevant to what we're doing, which is to interface that DSP to higher level functions. Sorry if all this is obvious; hopefully writing up our understanding of what's going on will help others.
