To be honest, Nedim, you are making this sound a lot simpler than it is. Mega voices aren't JUST velocity switched layers. They are also non-pitched sounds, on single notes, which DON'T get transposed while the pitched ones do (that's quite a complex thing to get a single style Part to do on many arrangers), in addition to trigger notes that don't make any sound at all, but affect the notes that ARE playing (chord mutes, for instance).

Sure, there are similar things on GIGA layers and triggers, and many of the VSTi's out there, but the issue is, how easy (if it possible at all) is it to map the control triggers from one format to another..? They are CERTAINLY nothing like each other, one system may rely on CC#'s, another on specific notes that need to be held in combination with other notes being played, etc., etc..

Now, I don't know about you, but I don't know of ANY translation software that is complex enough to make rules for these types of gross differences so that the translation is automated (converting note#'s into CC# of a specific value, for instance, and another value for note off). And that leaves you basically hand converting each of the styles actual note data, part by part, division by division, chord type by chord type... For every style you want to do that on.

Once again, there's this aura of theoretical knowledge about this, rather than actual practice. Lord knows, I've tried my level best to get Yamaha Mega Voice Parts to translate well to Roland's... I'm not making this sh*t up! Perhaps AFTER you have actually TRIED to do this, and perhaps shown us the results, you can start to tell us all how easy it is?

BTW, Yamaha's SA2 technology can't be used in the style, but Korg's DNC voices CAN. Along with a VERY complex Guitar Mode that works in style mode, and gives very accurate guitar voicings and strumming/picking patterns that are interactive with the player. While, once again, there are VSTi's out there that do strumming and picking, it is usually in audio, for one thing, and uses a COMPLETELY different set of trigger notes and control codes. Which once again makes translation a 'by hand' note for note issue again.

I agree that in THEORY, a multi-sampled drumkit OUGHT to translate reasonably easily to a GIGA kit with more layers (though you may be forced to heavily edit the GIGA kit to reflect sample layers that aren't simply increased force ( (tom-toms that turn into tom-tom flams at the top of the velocity range, for instance), but admittedly, this is a 'once done, finished with' process. But some of the more complex things that Mega Voice technology, and DNC voices can do go FAR beyond this, I'm afraid...
