When shipped from the factory, the Expression Pedal is assigned to control Loop Volume. The
Expression Pedal can be assigned to control different parameters using the Expression pedal options
menu, accessed by pressing the Parallel / Series switch for 2 seconds. The digit will show “E” and
the current Expression pedal assignment (either “U”, “A”, or “≡” meaning Loop Volume, Loop Aging,
or Varispeed respectively). Move the encoder to select the desired Expression pedal mapping.
This is the default function of the Expression pedal. Moving the expression pedal towards the heel will
turn the loop audio down from the level set by the individual loop volume knobs.
When using the expression pedal Loop Aging control, toe maps to “no loop aging” and the numbers
go down from 9 to 0 as you move towards the heel.
A (normally open) momentary footswitch (connected via TRS) can be used with loop aging in place of
an expression pedal to get an instant “Loop Replace” function. Pressing the footswitch is functionally
the same as placing an expression pedal in the heel down position.
This option allows the expression pedal to control sample rate. Moving the expression pedal towards
the heel will decrease the sample rate, decreasing pitch and increasing loop length. When the
Expression Pedal is moved it takes control of the sample rate and will remain in control until the
Pitch Up or Down functions of the Varispeed Remote Control mode are used. Varispeed Expression
is the default function of the Expression pedal when the Varispeed Remote Control mode is active.

When a MIDI Beat Clock is present, the Infinity 3 will synchronize its actions to the MIDI beat clock,
acting as a slave device.
Once a loop has been recorded with a MIDI Beat Clock, Infinity 3 will constantly readjust the loop
length to stay synchronized. This active MIDI synchronization prevents dri, and guarantees that all
synchronized actions happen on time at the start of MIDI measures.
