i can do almost everything quite easy
build the thing, no prob i probably have most of the stuff.
generating 8 frequencies in scope..duh
extracting the amount of each frequency per input. probably can be done with 8 channel vocoder front ends, otherwise separate filters and envelope followers.
then i would end up with an 8x8 grid of 64 control values.
now to make them in to 1-? useful values of X,Y and Z
thats the last bit "centride function" if thats what he said. i guess its sort of an to give the absolute XY output positions when between the various positions i wonder if it can be done in scope?
it would be multi touch and fast enough to control synths and stuff. most multi touch only updates at 30hz, this works at audio speed. and it can be pressure sensetive and look at that drum control he did there

theres loads of synth and effects you could do with that in scope
