How to install:

• The currently active preset and pattern are no longer automatically saved
• The load UI screen has been redesigned to make better use of the entire display
• In the load UI, one of the brightly lit pads (selected preset, pattern or sample) softly pulses. This indicates that this item will get cleared when long-pressing the Clear-pad
• The load UI now works as follows:
  • Short press
    • Select this section to be cleared with the Clear pad
  • Long press (arrow at the right edge of the screen points up)
    • Load the pressed preset
    • Load the pressed pattern
    • Load/deactivate the pressed sample
  • Hold the Load-pad + long-press (arrow at the right edge of the screen points down)
    • Save current preset to selected slot
    • Save current pattern to selected slot
    • Open pressed sample in sample editor

There are many more improvements in this version, the full list can be found in the release notes
