It's been a few years since I've posted, hope that's ok. :) Doing lots more music. To go along with my solo performer show, I've started creating tracks in Caustic to use with a looper. The process is create a track for a song (think like Sweet Home Alabama), produce/master/normalize (btw, saw some info on the mastering app, really need DR and LUFS metering for international standards), play from phone with guitar into looper, and have one-man-band live show. This has been a game changer for me. Just wanted to share some of the ways Caustic is being applied. I may be able to link a Facebook vid if anyone is interested.
Edit: Forgot to add that why I'm using Caustic over other things is it's nice to tap the tempo, and tune a drum kit to be similar to the recorded version. I'm always adjusting the Tune and Decay knobs in Beatbox to get closer to a recorded kit. From Mustang Sally to Pride and Joy to Melt With You, fun stuff.
Do the (guitar) loops drift out of sync with caustic if you don't' run caustic through/inside the looper? I guess looping a machine with a built in MIDI sequencer seems counter-intuitive to me, but I think I can imagine why you would do it that way.
I play along with the recorded track so it stays in sync. Have a little Saturn Works mixer pedal to combine phone and instrument and that goes into a Ditto Looper. Use a Key9 pedal to add other sound layers on top in addition to guitar.
Oops, forgot to answer your question. :) I'm guessing it would go out of sync. Anytime I've run 2 loopers in parallel, did a duo with a looping friend, it is impossible to sync. Now, if there was like a turntable like interface so you could resync and remix a la a DJ, that would be awesome.
