Good to hear it's working out Jens.
It does take some (slight) adjustment to your technique and since pitch bends are not available (yet), it won't feel quite like when plugging a guitar straight into an amp. There'll always be some loss of "emotional expressiveness" that we're used to when playing the real guitar......hopefully, MG will someday evolve into something very close.
For best results, you'll just have to tweak the settings in MG to your liking AND also adapt to the sounds of the synth when playing.
I actually recorded a little "synth" solo last night with it and it tracked very well.....playing cleanly will definitely improve in
not getting odd notes/odd responses.
