Sound Set for Edirol-Sibelius 5

Hi you all.

I use the Edirol Orchestral as an VST for Sibelius 5, yet I still do not find the Sound Set, that is, the archive that tells Sib where every sound is placed in Edirol.

What I'm forced to do just now is to send each instrument through a specific channel, then have the desired sound in that channel in the Edirol pannel (using a performance file). Not too complicated but yet not as easy as it should be. Worst of all, to change sounds through the piece (say change from arco to pizz), the Sib text does not work, so I have to add an especific MIDI message with the bank-program the sound is in. So I supose it won't playback properly if I use another device.

I'd really thank some help on this mess
