Input – determines the input source used for loop recording
there are three settings:
1 Lead + Guitar – all voices and guitar are recorded to the loop
2 Guitar – sound coming in via the inst in is recorded to the loop
3 Lead – input from the miC in is recorded to the loop
4 aux - only the signal from the aux in is sent to the loop
5 aLL - if you hear it, it’s going to the looper
Undo – toggles the loop undo function
there are two settings:
1 on – undo is active and may be used to undo the last change made to your loop it is com-
mon to use undo when you’ve added a loop section that you’re not happy with and want to
try it again Loop time is 15 seconds
2 off – disables undo, freeing some memory for additional looping Loop record time is dou-
bled to 30 seconds
Loop Feedback – Controls the amount of loop record feedback
When recording a loop with multiple passes (or parts), the signal from the first loop pass is added to
the next, and so on if all of these passes were put together at 100% volume, the loop you’re working
on would get louder, and louder, and Louder, until it was distorting the output of the device
the purpose of the loop feedback control is to prevent this volume increase from happening when
you record a new pass to the existing loop, it is recorded at 100% volume, but the existing loop is
blended with it at the Loop feedback setting
the calculation works like this: input + (Loop x Loopfeedback) = Loop output i e input + (Loop x
90%) = output *run away! scary math!*
Most users find a setting of around 90% works well, but you may find a different setting that works
best for you
