Recalibrating sub 37 pots after board 2 replacement

I am new to sysx and have followed the instructions regarding downloading Midi-ox on my lap top and I I have the 3 calibration files. Running the low pot one now. It’s been half an hour and the midi light is still red. Lots of lines of text on the midi-ox output display. How long should the procedure take? not knowing this means I don’t know if it’s all working. How long before the red midi light flashes? Thank you!

Have I got the midi port routing right?

From your description and the screen shot, it looks as if there might be a MIDI loop. What are the physical MIDI connections you’re using?

I can’t test with MIDI-OX at the moment, but you can take these steps to eliminate any loops, and then give it another go:

  • Do not connect the MIDI out on your Sub 37 to your PC (just leave it unconnected).
  • Make sure any MIDI through functions on the Sub 37 are switched off.
    To do this, press the MIDI button and set the ECHO functions to off:
    MIDI MENU 2.3 > ECHO DIN IN: OFF
    MIDI MENU 2.4 > ECHO USB IN: OFF

Many thanks for you assistance. I only had a single USB single USB connecting the sub to the lap top. I adjusted the subs midi settings as suggested an voila! The midi light flashed red in a second. Iam off to try it out and will let you know. Many thanks again.

Hi again. Thanks again for your support! Pleased to say the sub 37 is once again fine and dandy. :smiley:
