- Added waveform generic API to create waveforms, and use period instead of frequency in waveform (avoid division on MCUs) - Introduced 'def' struct in ADSR API for reuse - Multi-track MML parser and compilation - Added some samples from https://electronicmusic.fandom.com/wiki/Music_Macro_Language - Added scale.mml for testing
