Tobin, thanks for putting up these samples.

Clips #2 and #4 would be most usable for me: rhythm guitar chords rather than single note or mixed chord/single note comping.

I agree with the OP about the general usability of these guitar parts. To my ears, most of them sound like they are comping rather than playing rhythm guitar. The few I use I always set to "simple" to try to get a more basic sound.

Also, if I were a producer asking a session pro to play rhythm parts, I would ask them not to “play” the turnarounds—rather to simply keep steady rhythm. Other instruments, not rhythm guitar, should "play" the turnarounds, in my view.

None of this is meant to take away from the playing these RealTrack players do. It is fabulous!
