pcmsynth can import sfz patches, if they're not compressed to ogg files, that's ok. the biggest benefit of using sfz patches instead of sf2 patches is the file compression.
so here's my idea: ios supports aac/m4a files. would it be possible to compress the sfz' patch wave files to aac/m4a and import them into caustic?
a compressed sampler format would be great! another great thing would be a "next" button which selects the next patch.
another feature request would be "chord pads/buttons".
