Foot SW: #82 (Foot SW: CC#82)
This AMS source receives MIDI CC#82. It can also be
generated by a foot switch connected to the rear‐panel
ASSIGNABLE SWITCH input, if the Global Foot Pedal
Assign parameter is set to Foot SW (CC#82). For more
information, please see "Foot Switch Assignments" on
page 349.

Tempo
This lets you use the system tempo as a modulation source.
120 is the center, for a value of 0; 60BPM is –99, and 240BPM
is +99.
Note that this is different from actually syncing to tempo;
for that purpose, use the dedicated synchronization
functions for the LFOs, effects, etc.
Gate1
Gate1+Damper
Gate 1 is triggered by a new note after all notes have been
released, such as at the beginning of a phrase. Gate
1+Damper is similar, except that it is triggered by a new
note‐on after all notes and the damper are released.
You can use this to reset the Common LFO. For instance, to
create an effect similar to the per‐voice LFO and Step
Sequencer's Key Sync Off setting, use Gate 1 + Damper as
the reset source.
Gate2
Gate2+Damper
Gate 2 is similar to Gate 1, but it triggers with every new
note‐on, even in the middle of a legato phrase.
Gate2+Damper includes the damper pedal in the equation,
as shown in the diagram below.
Note: When used as a reset controller for Common LFO,
Gate2 and Gate2+Damper will have the same effect.
