This would be cool. I really like the sound of this feature.
Right now for my main gigging band, I use one primary preset which uses a single amp/cab set up for all scenes. My scenes are set up with different combinations of effects and the functionality of the expression pedal changes with each scene. I use the FM3 to move around scenes and engage the tuner. I did change my scene layout to toggle between two scenes rather than do one scene per button. So the way my scene views work is:
View 1
- Switch 1: Toggle between scenes 1/2 (clean and clean with delay, exp pedal is auto-engage wah). This is kind of my homebase.
- Switch 2: Toggle between scenes 3/4 (Both dirty lead, each with a different pitch effects mixed in with the exp pedal - No wah).
- Switch 3: Toggle between scenes 5/6 (5 is a toned down clean sound to comp behind the keyboard player, 6 is a super lush clean sound for special use).
View 2:
- Switch 1: Toggles between scenes 7/8 (a more bluesy dirty tone and a lead tone with wah). I don't use these much.
- Switch 2: Actually the same as switch 1 in view 1. Allows me to land back home quickly if I need scenes 7/8.
- Switch 3: Tuner
Long press on switch 2 will take me to the master layout as normal.
I run a EV-5 expression pedal and a two switch Mosky. First switch scrolls through scene views, second switch is tap tempo (I use a lot of delay). I also run a passive volume pedal before the FM3. As stated, the expression pedal function changes based on the scene.
I do have a couple of small variations on this preset for dramatically different effects I may want to employ (including say the position of the pitch block).
I do a similar thing for my metal/hard rock band but my home base is a dirty rhythm tone.
