lovely little module, so much fun and girth, no brainer, bang for the buck is amazing!
in terms of what fits on the eprom - shorts sounds like hats or rims work well and sound almost like the original.
if you want to use the pitch in a way that makes sense, musically speaking, i´d tune up my own samples (if you order your own soundchips), in order to have a more useful range overall. bassdrums sound very raw and in a certain way nice for jamming or live use, but loose too much attack and punch due to the conversion. anyways - a must have!
