Luciano Martorella	c19c6dddcb	- Added sequencer from binary 'waveform' and ADSR data. ... - 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	2021-05-18 20:18:29 +02:00

Stuart Longland	d1cbf66261	waveform: Add support for frequency scaling. ... For conniseurs of DDS frequency generation, we provide the option of scaling the integer frequency so that frequency may be specified to fractions of 1Hz. This is useful in musical applications where the frequency of most notes is a non-integer value.	2017-07-25 07:59:23 +10:00
