I apologise if I was not specific enough in my previous posts regarding the M5 program change features. You are correct in stating that the M5 will not save factory presets unless they are specifically saved via the "user presets", with one notable EXCEPTION. The M5 "will" save all user edits to any of the "factory" presets when the M5 is being used as a MIDI slave to an externally connected MIDI devise. As I have stated in a previous post, I am personally using an M5 as a MIDI "slave" to a Roland GR-55 and was saving any of the factory presets of my choosing, including edits" without having to save these presets to M5 user preset locations. The M5 saved these "edited" factory programs as a MIDI slave to the GR-55 and would always recall those saved parameters and presets whenever they were triggered through the MIDI out from the GR-55. Even after powering both units down and re-powering them, the preset allocations on the M5 would always "remember" the MIDI data send info from the Roland GR-55.

I ran into a problem a month ago when the M5 all of a sudden failed to receive program changes from my GR-55. Now a month later after having my unit repaired it now works again  just as described above. As a matter of fact the repair facility told me that Line 6 is notorious for not being up to date on the detailed operation of many of it's products and because of this there is a lot of confusion among the users of it's products. After the misinformation or lack thereof on this site I wholeheartedly agree. They personally witnessed the above MIDI function of my personal set up when I went there to pick up my M5 .

So once again, I really do not appreciate being told by so-called experts that my facts are incorrect when in FACT they are.  I suggest that if you have your doubts concerning my above detailed comments that you actually use the M5 as a MIDI devise as I have and then voice your opinion on the matter.
