Dweezil called me tonight, wanting to have a footswitch on the MFC-101 which would change an FX LOOP block in his preset from "stereo" to "split," where "stereo" would be normal FX Loop operation, and "split" would patch the FX LOOP in on the left and allow dry signal on the right. An existing footswitch turned the FX LOOP on or off.
I came up with something different that does the same thing. It works! The artist was very happy.
PREPARATION/REQUIREMENTS:
MFC: Two MFC footswitches are designated. The first is labelled "LOOP STEREO." The second is labelled "LOOP SPLIT." We used 16 and 17.
AXE-FX: A Volume block is connected in parallel to the FX LOOP.
--[CAB]---[FXL]---[GEQ]--
........\-[VOL]-/
The VOL block's INPUT MODE is set to "RIGHT ONLY". Its BYPASS MODE is set to "MUTE".
On the MFC:
IA 16 Axe-Fx mode set to NONE
IA 17 Axe-Fx mode set to NONE
Switch 16, Command 1 turns the FXLOOP block on and off.
IA 16 c1: CC#59 Ch 1
IA16 c1 Off 000 On127
CC#59 controls the FX LOOP by default. It's BYPASS MODE is set to THRU.
Switch 16, Command 2 makes sure the VOL block turns OFF whenever this switch is used.
IA 16 c2: CC#25 (ext 10) Ch 1
IA17 c1 Off 000 On000
Modifier on Bypass Mode of the Volume Block is assigned to EXT10
Switch 17, Command 1 turns the FXLOOP block on and off.
IA 17 c1: CC#59 Ch 1
IA17 c1 Off 000 On127
CC#59 controls the FX LOOP by default. It's BYPASS MODE is set to THRU.
Switch 17, Command 2 Turns the VOL/PAN block on when needed, and sets the FX LOOP "Balance" so wet is on the left in "split" mode.
IA16 c1 Off 000 On127
IA17 c1 Off 000 On127
Modifier on Bypass Mode of the Volume Block is already assigned to EXT10
A Modifier on Balance in the FX LOOP moves it right in split mode.

Switches 16 and 17 are placed into a mutually exclusive group so they cannot both be on at the same time ;-)

So that's it. You can substitute lots of other blocks into this setup too... If you wanted to, you could use a different EXTERNAL to control the Bypass Mode modifier of the FXLOOP rather than "hard coding" it to #59.
Have fun!
