Hey y'all, 
Tried something two nights ago which I'm sure some of you have tried before, but it was super rewarding.  I had six violins with me in front of which I looped and had each one capture a track of looping on live violin, then I faded out the loop.  Worked like a charm and it was beautiful.  
However... with the size of the venue I'm afraid the crossfade got lost, let that be a lesson to me. Next show with this band, I'll not use the looper to create, but rather just the musicians!
In any case, we had a great time and someday I hope to share some looping work from this show with you all. 
I'll post a few links here to pics and a review... 
Cheers, all!
