The title pretty much asks the question. It would be a tremendous boon to me if 4/4 and 3/4 had the ability for the strums to swing on on request. 2-measure syncopation would also be nice someday but swing lets us play many ballad types not currently doable on Strum Machine.
I know how to fake swing using the 6/8 and 9/8 patterns but that places downbeats on every beat.
I would be happy to alpha test anything you can concoct in that regard.
Keep up the good work!
