standard Undo or Redo functionality however, you can snap to any
desired sample rate using the remote switch. In ARM mode, pressing
both Remote Switches at the same time will snap the sample-rate
to the sample-rate used to record the currently armed Loop. In ALL
mode it will always snap to the sample-rate used to record Loop 1.
This behavior will save whether the recording sample-rate was set
using the Remote Switch or the Expression Pedal and set the Infinity’s
state accordingly. Caution: By default, loop audio that is recorded
at 48 kHz can only get longer and lower in pitch. To enable sped-
up, shorter, and pitched-up loops, this initial recording rate must be
lowered before recording audio.
There are many ways to change the sample rate on the Infinity. Some
of them are best thought of as sample rate changes, while others are
best thought of as pitch changes. All of them change both the pitch
and length of recorded material. See the table on the next page for a
listing of how pitch changes relate to loop length.
When using Varispeed, the expression pedal provides control over the
complete range of sample rates. It is mapped to control the sample
rate using Expression Mapping (page 39) or while in the Varispeed
Remote Control Menu.
For more precise changes, the Remote Switch can change the sample
rate by a pre-defined musical interval. By default, Reverse halves the
sample rate (octave down) and Undo doubles it (octave up). The pitch
change controlled by the Reverse and Undo switches can be custom
set (on a preset-specific basis) to other intervals, using the Infinity
Application (for example, up 4 semitones and down 4 semitones).
For more information, see the Varispeed Remote Control Menu in the
Remote Switches section on page 33.
Complete MIDI mapping allows you to change pitch by sending MIDI
Notes, and also tracks changes in the MIDI Beat Clock’s tempo. For
a complete understanding of these controls, see the MIDI Section on
page 48.
