- Fixed a bug where the first 0.25 seconds of a MIDI-to-audio render were silent. - Fixed a bug where, when bouncing in a DAW, the instrument was sometimes not fully loaded. - Fixed preset save/load when using a DAW host. - Added an option in General Settings to choose a different pitch-shifting algorithm. Three pitch-shifting algorithms are currently available. The previous pitch-shifting behavior remains the default.
