AJ, thanks, i see the misunderstanding now..

it is interactive in the sense you start it out with the
key and the first chord, but then it is just a loop
with a preset chord progression, right?
is there a table available that displays the progression
for each of the riffs? one progression can fit many standard tunes--if one can figure out which set of tunes would fit
the preprogrammed progression one could solo with
another instrument (in my case sax) over it.

also, how many bars is the progression? is it the same # of bars for each riff? does it include a bridge?

as far as which OS, i have no idea..i tried it at audioworks
in ct..but what difference would the os make for the riff feature? tell me what updates to the riff feauture were
offering vs the first riff os?
