Sending a MIDI Stop command stops all loop audio regardless of Arm settings.
Sending a MIDI Start command starts both loops in All mode and only the armed loop in Arm mode.
Sending a MIDI Song Select command will change preset banks, in order to move between different
loops during performance. Allow up to 4 seconds for song select changes to take effect.
For precise changes of sample rate for the purposes of a pitch change, the Infinity accepts MIDI
Note Control.
MIDI Notes C5 to C7 change the sample rate between 12 and 48 khz. The looper starts at 48 kHz, so
if you want to raise the pitch of a sample, lower the sample rate before recording.
MIDI Notes C2 to C4 change the sample rate between 12 and 48 kHz, and Stutter the loop. So playing
these notes will change the pitch and replay the loop, which creates a “mellotron-like” sound. Like
above, the looper starts at 48 kHz, so if you want to raise the pitch of a sample, lower the sample
rate before recording.
