Yes it's a new parameter. That's a bug. It was supposed to have been fixed in the latest firmware?I've just updated my FM3 firmware to most recent and noticed the presets I'm working on sound different. The mids are sucked out. Is the 'high mid' function in the drive block new cause I can't remember? It's defaulting to zero- not sure I would have done that . . .
It should be set to 5 to have no effect. I used the 'batch' function to change it to '5' in all channels of all presets for Drive 1, then 2, then 3 (just in case), I have never used Drive 4.
