This gives an idea how RealTracks can work using the same guitar but recorded in many patterns/styles to allow change at any beat or bar.

Holds are made by selecting the start of the bar up to 4 bars long then it can be moved a bit earlier with "Edit Riff", it can also be used for a push by generating on the start of a bar them move and resize with "Edit Riff", a shot can be made by shortening the Holds quick.
UserTracks won't generate where a Hold C... or Shot C.. is so if this is used for other track freeze them then remove the Hold/Shot to enable the generation of the UserTrack Hold to work (until an option is added to BB to allow UT to play through a Hold).
