I'm using the Send/Return on my 100MK I for my Trio+. Minor problem has been when I'm not using and it's not plugged in, I have go into BTS and turn the S/R loop off for each tone I'm using. Was wondering if anyone else has run across this and maybe has a workaround? I don't see any global setting in BTS for the S/R to set the default to Off. I'd still have to turn it on when using the Trio+, I play without it more often and I'm fiddling with stuff anyway when I use it, so it'd be less hassle if the default was off..
