Latest firmware: 1.0.3

1.0.3

What's new in 1.0.3

MX initialisation when powering up standalone. MIDI Stack revision. Init/Factory reset button combo clears hung MIDI notes and resets MIDI input to middle C. Only Factory reset (5 button reset) initialises the parameters in settings pane. Major or minor firmware update correctly initialises MX patch. Hold shift and turn diffuse happens instantly instead of waiting for shift menu to appear. Tweaked the looping envelope (responds to retriggers by going to attack phase rather than resetting to 0 which was causing clicks in certain configurations with Gate->VCA enabled). MIDI Channel selection autosaves. MIDI CCs mapped to MX Nodes quantise correctly to 0 when a MIDI value of 63 is received.
