This version of GGSound features compact instruments, as well as additional bug fixes since v1.0. This should not affect most users, however in earlier versions, it was possible to have three, 256 byte sequences for any given instrument (volume, pitch, and duty). It would be uncommon to create an instrument with sequences this long, and usually volume sequences are the longest. So now, all three occupy one 256 byte sequence in version 1.1. As a result, the engine performs better and the data is a bit more compact.
