  • add notarization to build for Mac OS Catalina compatibility.
  • fixed image creation issues with newer Mac OS SDK.
  • fix an issue opening the window while modulating parameters in Bitwig.
  • start "Save as..." file dialog from most recently used directory.
  • fixed an issue where sequencer key trigger would not always restart sequence.
  • added option to quantize the sequencer rate to small whole number ratios.
  • added option to change the "x" controller number for MPE input.
  • fixed voice fighting with OSC and latest Soundplane app.
  • increased some patcher param ranges for MPE control.
  • rotate through available voices when receiving MPE.
  • Kaivo: fixed low resolution of body wet/dry dials.
  • Kaivo: increased granulator max source length to 16 seconds.
  • Virta: Fix corrupt signal from the audio/noise output leading to audio freeze in some hosts.

Windows versions require Windows 7 or later. Windows 10 is recommended. Mac versions requires OS X 10.7 or later and a 64-bit plugin host.
