more instruments:

Real wah for funk/pop/r&b styles
Real Hammond organ comping and sustained variations
Real Nylon guitar for bossa compings
Real Horn sections - ton of things you guys could do with this
Real Vibes - no exactly comping but harmony overtones would be cool
Real Bass - funk/jazz funk (chuck rainy, wilton felder) and disco
Real Funk Guitar - clean "wahka-chicka" stuff

more variations:
Real Jazz instruments targeted for higher BPMs (Mr PC at 220 is a bit fast for the current patches i think)

And last but not least, is it possible to add some kind of "add-on" that would allow tone "modeling" to the midi stuff. like line6's pod to the melodist and soloist files to make them soundmore real and to give tonal choices to pair up with the real band?? if you guys could do this it would sell!

thanks
