- New: Temperament editor allows numerical input of cent values.
- New: Console view: Visual discrimination of combination buttons from other buttons. Highlighting of last selected combination.
- New: Previous combination / next combination can optionally cycle within the current bank or switch to previous / next bank.
- New: Console view: New stepper window with large buttons for previous / next combination.
- New: Settings view: Buffer duration is set by number of frames instead of milliseconds (which depend on the sample rate). The actual buffer duration is still shown in milliseconds.
- New: A noise generator for preventing certain amplifiers from entering a sleep mode when there is no audio signal.
- New: Low-latency buffer sizes of 128 frames (2.9ms) and 64 frames (1.5ms). Do not use these on old devices like iPad mini 2, in particular in combination with convolution reverb.
- Changed: Smaller internal buffers for convolution reverb, to further reduce latency.
- Fixed: Quad convolution mode was broken.
