The guitar is sent to the receiver and out to the pedal chain onstage. It goes through a tuner pedal, a bass pedal (for turning the guitar into a bass guitar), a boost pedal (for quiet guitar picking or solos), and finally through the vocal harmoniser to allow it to shape the vocal into the correct harmony. It’s then sent back to Ableton Live for processing.
In Ableton Live, the signal has various plugins applied to it (EQ’s, compressors, etc) and then is sent to a plug in called Mobius 2.
This plugin is a software looper that loops all incoming audio sent to it in real time. The software runs on custom coded scripts that tell it how to behave and what to do when it receives a midi note from the Sonnit pedal. This could be something simple like record or overdub, or something complex like multiply the loop length by 3, and the insert 1 loop length of silence.
This allows the Mobius looper to be much more customisable than stock hardware loopers from Boss or Digitech, although with a lot more time invested towards it!
The audio is then sent back into Ableton and out to the mixing desk.
