New Dell laptop, Line 6 Flextone III amp with MIDI etc., Riffworks software. What do I need to run the Riffworks percussion tracks through my amp at the same time i lay down multiple tracks. i.e. I would hear the drum track, lay down a rhythm track, then listen to both while I lay down a lead track, listen to all as I lay down a harmonica track, etc - what do i need to accomplish this?

I want to record one track, listen to it as I record a second track over it, listen to both as I record a 3rd track, etc. etc. etc.
