While we're on this...I don't have a 707/727, but I do have a DDR-30
drum module. Anybody know how the sounds are stored in that? (I know,
in a ROM...but how are they encoded, and what would I need to convert
standard PCM .wav to it?) As one
might imagine, I'd love to get the TR-505ish (or maybe identical)
sound set ripped right out of the thing, and something much better
substituted in its place.
