The Yahoo group participants seem to be more interested in MIDI only, as I've noticed ever since RealInstruments came out. Nothing wrong with that, but I like my RealTracks. But I can see their point in that many of the new features are Real based, not MIDI based - no new MIDI styles, enhancements at the track level to accommodate RealTracks (but actually benefit MIDI tracks as well, but is not as apparent), no updated DXi synth (to replace the VSC, which doesn't work in the newer Windows), etc.
Folks on this forum seem well pleased at the RealTracks features; so it is interesting the difference.
I read postings from both the Yahoo group and here.
