CHAPTER 2. ANATOMY AND FUNCTIONS 14
For details on how to use the Expression Pedal, see Expression Pedal
Functions, page 39.
MIDI In
This provides a connection for MIDI beat clock sync (slave), or a MIDI
controller. Infinity Looper will sync to MIDI whenever a MIDI Beat
Clock signal is preset. The Infinity Looper can also be configured to
obey MIDI Start, Stop and Song Select, as well as CC/Note control
over every feature (complete MIDI mapping). For more information
and instructions, go to page 43.
USB
This provides a connection to a PC or MAC computer for loading and
offloading loop audio, preset management, audio routing configuration
and firmware updates. There are no drivers to install−just connect to
your computer and you’re good to go. For more information, go to
page 49.
When the USB port is connected, the Infinity boots into USB mode
and will not function as a looper until the USB is disconnected and
the pedal is rebooted. Save any loop data you wish to keep before
plugging the Infinity in via USB.
