Sometimes it's useful to have a dedicated footswitch set up to control BPM settings on a global basis.
Here's how to set it up:
1. Press MENU.
2. Turn SELECT knob to select CTL/EXP.
3. Press SELECT.
4. Turn SELECT knob to select CTL4.
5. Press SELECT.
6. Turn Knob 1 under the Display screen to SYSTEM.
7. Turn Knob 2 to turn ASSIGN OFF/ON to ON.
8. Turn Knob 4 clockwise until you see: BPM TAP.
9. Press EXIT 4 times.
NOTE: When selecting CTL 4, the assignment will be controlled by the "B" pedal of your FS-6. Choosing CTL 5 will let you control global BPM with the "A" pedal.
