XG works does not respond in real time. It allows the user to step input chords and style variations that can be played back from within the program in the way a seqeuncer plays back a midi file.

One man band ( my personal favorite ), Real Time Style performer, and live styler all play back yamaha type styles with chord input in real time. The only drawback if there is any is to remap the XG sounds to fit the xp-60. Jammer Live plays back Jammer's own proprietary styles in real time with chord input. Good program from what I've seen. I use Jammer Pro, which allows some very detailed and easily varied styles to be made almost instantly, ( as opposed to repeats of prerecorded styles that never change ), but the drawback is that the data is step entered, like XG works, so it isn't useful for live work.
