Thanks for the feedback guys!

Yeah, very good vocals on 'Dreaming 'bout Dancing', definitely
not generated by BIAB

It´s reassuring to hear that you like the sound of the chords.
Steinberg used to have (still have?) a product called virtual guitarist,
which sounded good but sometimes lacked certain chords. That could cause
an unwanted "hole" in your song that was difficult to fill...

I read a thread that gave me the impression that the RealTracks consists
of recordings of progressions in three different scales. That suggests they
only have to pitch stretch up and down 1-2 semi-tones, which seems acceptable
to me.

I must admit I'm a bit worried about the hold issue though. If there
are short chords in fast style I guess that could be a problem.

Sometimes it´s possible to create longer notes by time stretching
or looping in a sampler like Native Intstruments Kontakt, but for
some material it's not easy...like distorted guitar chords. I would
probably try this after exporting the tracks from BIAB.

At the moment I´m not sure what to do, maybe wait and see how RealTracks
develops or put an order right now?
