Varispeed

Varispeed allows you to change the pitch (and speed) of your looped
audio by altering the recording and playback sample rate. This change
can be made in real time using an expression pedal, remote switch,
or MIDI. Further details are provided in the Remote Switch section
(page 33), Expression Pedal Functions (page 39) and MIDI section
(page 43).

Push and hold down the Reverse switch to allow user control of
Varispeed.

The sample rate can be set anywhere between 48 kHz to 12 kHz. As
the sample rate is increased or decreased, both the pitch and length
of the recorded audio changes. The sample rate is a global parameter
and affects both loops simultaneously.

During Recording or Playback, you can use the Varispeed Remote
Control Menu, the Expression pedal, MIDI commands, or MIDI Clock
to adjust the sample rate as desired.

The current sample rate is saved at the same time that your current
loop is saved. Sample-rate changes cannot be undone or redone using
