Many of the RealTracks involve different types of guitar playing, which is often difficult to simulate with MIDI.

I see the suggestion in this forum for a Bossa nylon string guitar RealTrack, which I would like very much.

Well, here is another nylong string guitar suggestion--RealTracks of flamenco guitar playing!

That kind of strumming is very unique, and would be extremely difficult, perhaps impossible. to simulate in any way with MIDI, played on keyboard, etc. It would be really nice to have in a Realtrack.

It would not only be of use for someone trying to make flamenco music with BIAB or RB. That style of guitar playing could be used with many different types of music, if one had the means to incorporate it.

Therefore, I would suggest, in recording patterns with a flamenco guitarist--record a wide variety of strumming patterns, not only, however, with chord progressions common in flamenco music (although of course including those), but also with common jazz and pop chord progressions.
