Jeff Epler	1d1907b98b	synthio: Generalize vibrato into bend ... bend can be static, sweep, or vibrato	2023-05-11 09:31:07 -05:00
Jeff Epler	9a9f3229fa	synthio: Perform vibrato in pitch, not as frequency ratio ... Now the vibrato 'units' are 1.0 = one octave, 1/12 = one semitone, 1/1200 = one cent. Before, the units were somewhat arbitrary and were not perceptually "symmetrical" around the base frequency. For vibrato_depth = 1/12 and base frequency of 440, before: pitch from 403.33 to 476.67Hz, not corresponding to any notes after: pitch from 415.30 to 466.16Hz, corresponding to G# and A#	2023-05-06 21:35:20 -05:00
Jeff Epler	d2aca7eba0	synthio: fix per-note envelope & envelope modification ... .. and simplify the envelope advance logic by handling 'instant' values more intelligently.	2023-05-04 12:23:45 -05:00
Jeff Epler	021aaa4599	synthio: remove unused 'phase' from Note objects	2023-05-04 07:23:50 -05:00
Jeff Epler	a7da245ad0	synthio: Add synthio.Note ... This class allows much more expressive sound synthesis: * tremolo & vibrato * arbitrary frequency * different evelope & waveform per note * all properties dynamically settable from Python code	2023-05-04 07:23:49 -05:00
