Thanks for the reply MusicStudent. I’ve read your posts on Session Guitarist and watched a couple of videos. Thanks for those too. I tried to look for those older and cheaper versions of SG, but at least I didn’t find it right away.

This question may be stupid, but I still ask again: Can I use Session Guitarist on one track so that, for example, there is an X variation in the verse and a slightly modified Xb variation in the other verse? Or do these variations have to make their own tracks?

My intention is to make acoustic-based demos in which the songs themselves get their rights, either good or bad ...

Thank you too, Jim. I tried that free program on Amplesound, but it didn't really get anything out of Biab's mid guitar, so I removed the program. Probably the fault was in me. I’m also trying that Spicy Guitar yet. It seems to have "chords detection".

And Jim, that inconvenience of midi channels and channel numbers is one thing I should learn ...
