Basically, I added some signal re-routing code so that with a click
of a button, the sound in my looper's buffer is re-routed back into my effect
signal chain, so that I can do post-loop signal processing and
manipulation. For example, let's say I lay down a few loops with some
basic effects. I hit the re-route button, set my instrument down, and then I
can just sit back and use my effects as instruments to manipulate the loop
output, playing with parameters with my MIDI controller pedals,
etc. I can also continue adding loops (effected loops of the
original loops), or loop my live voice or instrument at the same time. I also
added a section in my rig so that I can add any recorded wav file to my mix
with a click of a button.
Anyway, I'm having loads of fun with the changes to my system, especially
with be able to play wav files. I can record a catalogue of wav files with my
uneffected voice or instrument, and then use it a raw content for looping fun
on the airplane, hotel room, etc.
Here's how the system looks now.
