There is hope in Roland Arranger keyboards .Roland VA 76/VA 7 has sequencer edit that you can insert different time signatures between parts which you want.But if you want to play it live its good too Roland Arranger keyboars like G-1000/em-2000 VA 7/76 have a button called "tempo reset" when you press it the style goes to beat 1 (and keeps on playing)that button was originaly disigned for if you sing and get alittle off beat you press the button and it goes to beat 1.I had a problem with different time signatures until igot VA76.
