Funny.. I also found out that some rhythm by default using JazzFunkGroovinRhythmSectn already gives me the required rhythm effect but after it regenerates, it may not always be on the bar I wanted.

Using the | Gmaj7 | A7sus,^A7sus.. : ^A7sus
will always make sure it's there, but the natural rhythm when the desired rhythm turns up (just a single A7sus) sounds more solid.

Wonder if there is a way to zoom in to a bar and freeze a particular generated rhythm ?
