  Hi Fred,

  Yes, I've managed to recreate your problem as described. Very 
  odd indeed.

  I leave my AN1x in Mode 2 99% of the time so I thought perhaps 
  the problem was specific to Mode 2. I rebooted my AN1x into 
  Mode 1 and the problem disappeared. My edited voice retained 
  the Filter Cutoff value when I removed my finger from the Ribbon.

  I rebooted back into Mode 2 and the problem did NOT reappear, 
  i.e., the voice behaved correctly with the Ribbon X assigned to 
  Filter Cutoff. Very strange?!?! Guess the problem is not specific 
  to Mode 1 or 2.

  So I edited another voice - making the identical Matrix 
  assignment - and of course it did not work! The Filter Cutoff 
  setting returned to 'center' whenever I removed my finger from 
  the controller. Aaargh!

  So, I powered off and on my AN1x and the problem disappeared 
  - again. BUT once I issued a program change the problem 
  reappeared! Very confusing...I rebooted BACK into Mode 1 and 
  the behavior was identical to Mode 2.

  I'm at a loss to explain this irradicate behavior :-( Perhaps we 
  need to report this to Yamaha.

  As a work around I suggest you use the Ribbon controller only 
  for dynamic changes and assign the Mod Wheel or an Assign 
  Knob to the same parameter when you require a fixed value.

  When I have time I'll boot up LOGIC AUDIO and place a Monitor 
  into my Environment Layer to see what MIDI CC's are coming 
  and going - and maybe test with LOCAL=OFF too.

  regards,

  Jon

  thx Jon for taking the time to check.

  IMO it really looks like an OS related bug. I think it's not worth spending too much time into this.
  at least I'm not alone having this very odd problem. BTW you did refer to mode1 and mode2 boot. Can you elaborate on this ?
