Because I saw the previous reply. I think the different realtracks put in Medley can be called in random order. >>

Yes. You are misunderstanding. RealTracks can be installed anywhere on any track when using the RealTracks Button on the Bar Settings Page. Each RealTrack must be installed one at a time and will insert at a specific measure and remain until changed by another RealTrack Button command. Multiple RealTracks can be inserted at a measure. Any RealTrack can be used multiple times on a track because each of the original Legacy Tracks can have up to 10 RealTracks. Every RealTrack can be used and they can be placed in any order on a track. Regardless of the order, the RealTracks cannot be shuffled but will play in the order they were inserted onto a track.

An additional misunderstanding is your question, " So, Medley can only play sequentially, but can't control shuffled play?" The question was made in regard to the RealTrack Medley sub mixer and it is different from inserting RealTracks using the RealTracks Button located on the Bar Settings Page.

The RealTracks assigned from the RealTrack Medley Page can either be selected to play sequentially or simultaneously. It's one way or the other, the two cannot be mixed.
