Wave data in the rom:
Single cycle loops for an octave of keys in 44.1kHz and 48kHz.
Demo singing is in 44.1kHz some custom flavour of ADPCM - haven't yet decompressed it. (added crudely decompressed previews for now, though)

If you have found out the exact ADPCM flavour, please e-mail me your findings to dtech@dtech.lv.
