Repeat being an "on/off" parameter. It would repeat the same strum indefinitely, starting immediately after the previous strum completed.
Then whatever chord that gets entered into the track gets the same strum settings and overrides any previous repeating strum… basically arpeggiated. Maybe it is possible now by having a one step track which repeats a strum over and over (?)
Then you would want to choose additional strum patterns, up, up&down, down, random, in order etc.
A lot of work I would think?
Maybe I’m in the minority wanting an arpeggiator instead of strumming?
