I was checking the PB value of the Nautilus JS X via Midi OX. The value should be 0 when returning to center but I am getting random numbers -40 -90 etc... Is the JS malfunctioning?



I would appreciate a reply or solution to the issue. I know I can replace the JS and should take care of the issue.

Thanks in advance.

It does appear to be malfunctioning. It should return to zero when centered. Replacing the joystick may or may not solve the problem. I have the same issue on my M3. I replaced the joystick but it didn't fix the issue. That made me think there is a small PCB for the joystick and SW1/2 panel buttons causing the problem, but I've not yet determined that's the case and my M3 is packed up in storage at the moment so I haven't been able to trace the problem. It might also be a poor ribbon cable connection somewhere. Re-seating the connectors could be an option that resolves it.

Pitch bend MIDI messages will be high resolution (14-bit, or 16384 values). Joystick X-centre position should display values of 00 for DATA1 and 40 for DATA2 in MIDI-OX, corresponding to a midpoint value of 8192 (there are no negative values). If the joystick is working correctly, these should be the last pitch bend values received by MIDI-OX, whenever the joystick is returned to centre position.
