Wavetable cycling via controllers

I'm thinking about how to "sweep" across wavetables with Rapture, which obviously can only be done with some good SFZ programming. If I want to crossfade between many wavetables as I modulate a controller, I assume I add the following language to each region:

<group>=X
<loccXX>=X
<hiccXX>=X
<off_by>=next group number
<off_by>=previous group number
<off_mode>=normal

That way I can have smooth crossfading as I modulate the controller. The only issue I see is this: I'd want to have a fairly fast attack and release as it crossfades, but perhaps I'd want a slower attack and release for the overall timbre. Is Rapture's own amp envelope separate from the SFZ file? If so, that would work for the attack, but if the SFZ engine has a short release, Rapture's longer release wouldn't have any effect. Any ideas on how to better achieve this? I've always wanted to do something like this, but never got the chance.

I need to download SFZ Toolbox and see if I can set up this kind of thing faster than in Notepad!

Thanks,

Oops, I think I named this thread wrong...I'm merely talking crossfading between wavetables via a controller only, no motion otherwise...though I suppose with even more programming with delay_beats and stop_beats, you could add motion plus modulation crossfading.

Interesting...

Perhaps [this thread] will get you going. Check out René's response [here], and Chad's contributions [here] and [here].

Well, I tried the xfin_cc thing, and it works OK, except it's REALLY STEPPY! Is there no way to smooth it? With such crossfading hardness, I don't know if I'll be able to use it.
