Hi Doug and welcome to THE Forum
I would suggest that the easiest way to do this is to set the individual Panel Memories with each Tempo, style (4/4 or 3/4), Sounds RT1,RT2 Left, Technicord etc.
Having done this, press and hold the 'SET' button in the middle of the Panel Memories. When the Panel Memory Mode screen appears, select 'EXPAND' and then Page 2. Make sure that 'RHYTHM SELECTION' and 'TEMPO' are 'ON'
After you have carried out this set up, you can either just play your arrangement into the sequencer, changing the Panel Memories at appropriate times as you play, or, if you already have your arrangement recorded in the sequencer, use the Step Record Editor, to insert the Panel Memory change points, in the Control track.
