I am about to enter the world of Arranger Keyboards, probably with the purchase of a PSR 2000. My question is: Is there is a way to add an audio track to a sequence created on the 2000. I know it cannot be done on the KB itself, but is there a module (hardware, not software) that can be MIDIed to the 2000 and sync an audio track with a song created on the KB?

Many of the sequences I've created (on my software sequencer) include a live bass, guitar, or vocal harmony track... and I'd like to do the same, but without having to depend on my laptop for live performance. Any ideas would be appreciated.
