For audio, try the following patch. For preset 1, store 0. in the left float box (moo) and -50. in the right (boo). Reverse them for preset 2. That should work, yes? The approach for "data" would be similar, but with multiplies rather than matrix~. I could send another patch, if that's not clear.
Yes i also tried that approach, but having a matrix of lets say
10X40, interpolating 400 floating-point number boxes at the same time
made the machine freeze -guess its the redrawing ?
So i tried to use an int-stack (multislider, hoping its represented
like this in max) as a matrix. Seems to be much cheaper ! ;-) like
this (in this example "only" 5 X 40):
-ull need the Lobjects and the Jasch-objects..
-> what about the jitter-experts ? probably much cheaper for bigger
