Fran - I've been poking around some this morning, and I did find some tunes that were done on Roland. As mentioned above we did a series of GM and GM2 format files, and we used a couple of different Roland units in the process. One was the Integra, but it really doesn't sound any different than some of the other Roland units we were using at the time since they all were leveraging the basic GM maps.
Said another way I don't have anything that we recorded that would show off what the Integra can really do...
