The picture is a little rough, but shows the basic idea.
So each of my 4 tracks (piano/synth, guitar, bass, and vocals) all go directly to the mixer.
From there I can adjust their "send" levels for how much of each track's sound is to be processed with effects.
I can also adjust the main levels for each track from the mixer too.
Then from the mixer, all tracks are sent to the amplifier depending on their FX Send Level.
The amplifier lets me add reverb, chorus, or overdrive/distortion at the press of a built-in foot pedal.
With these effects applied, I can then sample any of my four tracks either at the same time or independently, and have the effects included on the loop!
Finally, the loop pedal returns the FX mix signal back to the mixer for final levels, and from there it can be sent out to a recording device, or to a PA if not recording.
The only problem I've run into with this setup is if I want to record and listen at the same time. There is a slight delay (just a millisecond), but it adds up when trying to sample multiple tracks.
If I choose not to record, and just loop directly to speakers, this results in no delay between live and loop.
So I still need to find a way to listen to what I'm playing/sampling/looping while I'm recording that avoids this annoying millisecond delay. Until then, it's a great setup for practice, but still not quite ready to deploy on-stage... working on it... :)
