a new OS was just released for the Stage 3 with some fixes, but still no significant enhancements. Not even support for the new v4 sample format added yet which was mentioned some time ago:
v2.60 (2021-09-23)
- Improved handling of high-velocity strokes during quick key repetitions.
- Adjusted velocity curves for incoming and outgoing MIDI.
- Added MIDI menu option for “MIDI Out Velocity Legacy”. Set this to "On" to instead use the pre-v2.60 velocity curves, if needed.
- MIDI velocity curves for Extern Keyboard Velocity options were adjusted.
- Program Change messages were still received/listened to when set to “Off” or “Send” in MIDI menu, under certain circumstances. Fixed.
- Adjusted Volume Level dial acceleration.
