I've just spent hours sorting out the PM mode problem of it switching back to browse mode on the latest firmware. I'm using a Rocktron Midi Raider in the 5 bank 10 CC button mode, I also have an FCB1010. The problem only occurs for me when I have one of the CC buttons set to engage the tuner mode, as soon as I removed CN #31 from the Raider it worked perfectly in PM mode, hope this helps. Also both the FCB and the MR worked perfectly in PM mode until I started programming the CN's.
Hope this helps.
Oh also CN#7 on button 7 clashes on the MR as its also set to CN#7 on PED2 or PED1 which also puts the tuner on.
