Good! I'll check this out this evening!
First: I did start with the manual, as you have read i found limits that "I did not find in the manual"
My instrument is a stick-like or Warr if you wish tapguitar with three active outputs: bass, melody and midi. The last I did not mention before because I did not want to make it more complicated. Midi goes to a Roland GR55 that has stereo out (to return 3/4)
I have a bass guitar on the guitar input but this is not really needed as I do not play both simultaneous. but then I have to replug between songs.
I am good with limits and I will find them.
I come from an Axefx with extreme possibilities but no userfriendliness. I am happy with Helix (oh I use the rack version)
