new sound suggestion
first off, I think you might want to update the "toy piano" sound. when i select to use that as an instrument, the toy piano seems to sound like the default piano. also, for a new sound suggestion, if anybody's owned a toy by VTek, playskool or fisher price in the early to mid 90's, their learning toys had some pretty good sound chips for its music, which hopefully somebody can edit in a soundfont. also the sound chips used in those singing teddy bears from the same era, the ones that sounded 8-bit. just some suggestions.
