External Switch Custom On And Off Values - Fractal Audio MFC-101 Owner's Manual

EXTERNAL SWITCHES
TOG "TOGGLE" – Whenever any state change is detected in the connected switch, both the
ON and OFF MIDI messages will be sent in quick sequence (~250ms apart).
Use this setting if you want a connected MOMENTARY switch to behave as if it were
really a TOGGLE/LATCHING switch.
NOTE: In this mode, switch data is not sent on preset changes.
11. Press PARAMETER 3x to return to the first cursor position and repeat this process from step 4
for each additional connected switch or press EXIT to return to PERFORMANCE MODE.
NOTE: Unlike Instant Access Switches, external Switches cannot be given Axe-Fx functions simply by selecting from
a list. It is possible, however, to set them up for Control Change messages which in turn have assignments in the
Axe-Fx under its I/O:CONTROL page.

8.3 External Switch Custom On and Off Values

It is also possible to specify custom ON and OFF data values for an external switch, both globally (12.4.15 on p. 57)
or for a given preset.(12.1.8 on p. 45). This is optional and typically not necessary.
