Hi Prado,

RB apparently is a 'roll your own loops' program.



Whilst the tracks that I create are not loops, it is possible to think of RB in this light. Have a look the link Matt Finley posted for the RB tutorial and you'll see what I mean.
Quote:

1. RB opens *.sgu and *.mgu files.



Yes!
Quote:

2. RB permits regeneration of just parts of track (as well as whole ones, obviously) ... to hone in on what you'd like to improve.



Yep!
Quote:

3. You can pick any instrument to create/ regenerate any track you like ... till you find the one that sounds/ fits right.



Yes and you can even have a multitude of instruments on a single track as a piecewise fit. (I don't really use this, though, as I would simply create another track for each instrument.

So ... have you forsaken midi to hardware or softsynth entirely?



No. I find midi piano and strings very useful. I usually create a wav file from these midi tracks, though, so that I can apply DAW effects.
Quote:

And, are you using the audiophile pack?



No. I have the standard edition.
Quote:

You mention drag n' drop *.wav files ... so otherwise you'd be drag n' dropping *.wma, right? Not talking about the dxi render midi to audio ... but the Real Tracks).



I don't use the drag 'n' drop feature. I prefer to export my tracks to individual wav files and then load these, as a separate event, into Reaper for mixing.

You should start having a play around and see what you think!

Regards,
Noel
