On the Roland you need to press a seperate key to determine which strum it is to be, and from memory, it is the same on the Korg.

So you would play a chord with the right hand in normal piano voicing, then select the key range assigned to say "up strums" and it re-voices the notes to guitar voicings and plays an up strum, continuously, or just one depending on which key you select. The same applies to up AND down strumming and arps.

Real Guitar, and Real Strat operate in a very similar fashion. So if you can set up a midi patch to play both the strum type, and the chord played it can be embedded into a style on the MS. As I believe a style on the MS can have both audio, AND midi parts, although I cannot confirm as I have not played with it yet.

I am awaiting OS 5 (or 4.5) for the Q-Ranger engine to accept VST's as well as just the Giga sounds.
