Here is an overview of the rig I've put together that combines pre-recorded multi-track audio looping and guitar looping which enables me to play a complete song while also being able to rearrange or extend parts of the song live.
The rig uses the Electro-Harmonix 45000 multi track looper https://reverb.grsm.io/45000 , the Pigtronix Infinity looper and a Molten Voltage Tempode MIDI clock injector as the master clock source.
Building this rig, recording and learning to use the loops has been a great challenge, and I'll be recording some performance video as well, but first a description of how it all works.
