It's obvious it's doing all that, Brent is not inside the application. I did it the same way with Reaper scripts in ReaTrak.
So what is the solution to get better solos ? do we need to hire Brent for our tracks ? can we map them out and choose manually what riff we want where ?
If it's not working then a better way has to be put forward.
You can create up a UserTrack from them and set it to play the whole selected riff over your chords but you will get the same thing a lot of times that won't be unique for everyone.
I just think RapidComposer is more flexible as it will fit anything over the current chord/scale, unless Biab has ARA and Melodyne what can you do ?
"and professional guitarist."
At the moment it seems like the only way is to play it yourself or hire someone.
