I am using a Rocktron Midi Mate with my Axe FX. I normally use buttons 0-4 for presets and 5-9 for IAs. I want to use all 10 buttons for presets and an external 2 button switch for IAs. One to turn the tuner on/off an a second to set tap tempo. Can anyone confirm that this can be done? If so, momentary or latching switches.
