you mean like... .h264?

I meant obvious as in, is there some way people are using REX files in Vegas/Acid?

REXX - I wish!

"REXX - I wish!"Wow! Yeah, REXX (the King of Languages) would be great for scripting :-)

You mean like . . . legally?
You would need to contact Propellerhead directly and determine the license fees and terms necessary to produce a plugin for SCS applications.
Or one could start an open-source project and write all their code from scratch.

There are VST plugins that do REX and REX2 and that you could use in Vegas or Acid. I don't see why you'd want to though. Rex slicing doesn't sound anywhere near as good as Vegas's "elastique" time stretch/compress.

"...You mean like . . . legally?

REX is not a plug-in. It is an audio file format created in a standalone program called "Recycle!" Yes, you can import REX files in certain VSTI soft-samplers but REX is not a plug-in....its an audio file formatted with selectable beat segments.

I bought Recycle! version 1 back in the 1990's. Back then, before I owned a computer DAW (I had a Fostex 8 track & a Roland VS-880) I would process many of my drum loops in Recycle! (Recycle! would then export the "chopped-up" drum loop as a REX file AND an associated MIDI file).

I would then import the REX file into my hardware sampler (AKAI S2000) and import the associated MIDI file into my sequencer (Cubase VST 5.1). Then the MIDI file would be used to manipulate the REX file in exciting ways to change the groove around (not just simply changing the tempo). Back then, Recycle! was the best groove manipulation tool around. The EMU EmulatorX2 & X3 samplers with "Twist-a-Loop" does that (plus a lot more) all in one package.

Nowdays, all the modern DAWs (except ACID) allows the direct importation of REX files. Another area where Sony is missing the boat.

"...Rex slicing doesn't sound anywhere near as good as Vegas's "elastique" time stretch/compress..."

I don't know about that, but as explained above, REX allows much greater "groove manipulation" than what is available with elastique. Also, I believe REX files will accept greater tempo changes without artifacts.

I really don't think its fair to compare the two. Yeah, they both do time compression/expansion. In that regard there is a similarity but Recycle!/REX does much more. I think of Recycle!/REX as a groove manipulation tool.

"...There are VST plugins that do REX and REX2 and that you could use in Vegas or Acid..."

No. Not VST's...VSTI's. In this case it would have to be some kind of soft-sampler such as Kontakt, Halion, or whatever. But then it can be used only in ACID. VEGAS doesn't support VSTI's.
