Welcome PostmanJoe,

I also use BIAB in church. I record various BIAB parts onto my Digitech looper that is connected to the chruch PA. I can control the looper with a footswitch while I'm playing guitar. Sometimes it works to record various sections of songs as loops (this seems to work for sing-a-long songs when there is no set time limit). Other times I just put the whole song start to finish on the looper. I use drums, bass, and guitar parts mainly depending on how many other musicians are playing with me.

Good Luck

Frank
