Jick, I like my Jammer Live. It works great when I midi from my computer to a sound module. But if I use my Roland 88h wavetable, the latency makes unuseable for anything but the drums.I am able to set the latency to "0" in Jammer Live, but can only reduce the latency to 125ms on the wavetable software. The biggest problen is trying to play right hand parts.. If I use the arranger section to play the wavetable and the right hand on the controlling keyboard[its own sounds] it will work, playing chord changes early[ usually the default quarter note quantize will work. It is pretty cool and can work as a back up or occasional arranger service on the job or studio. But it really can't replace a pro arranger keyboard, for my needs..Still, I would say GO FOR IT!!! Fran
