Changes from 2021.09.20
This release fixes a significant bug in the pulse width behavior. If you've noticed that Castor & Pollux's pulse waveform sounds "glitchy" or "steppy" when changing the pulse width, this fixes that! Modulating the pulse width should now be smooooooooooth. If you liked the old behavior, don't fret! You can use the settings editor to switch between smooth and classic. This should also fix the occasional hiccup that can sometimes be heard when change pitch with a sharp envelope.
