Yeah, I've posted this both places to up my chances. The response, at least on the official forum, is usually pretty low. Especially Access' own people tend to be shy with commenting, even on the interesting questions and suggestions.
Regarding the topic, with these older viruses, I'd expect all you can do with the internal routing is adding effects and filtereing from other parts in the multi, as in nothing that has to do with the oscillators, and that the number of AUX buses limits the chaining of effects and filters for the same patch, but I might be wrong, as I don't know how this routing is done.
As mentioned before, I read something in some thread about it indeed being possible to affect the oscillator section as well, but it was an answer to someone having a problem with something, and there's always a chance that the one answering in that thread never actually tried this himself and just assumed this was possible.. Who knows? Well, I'd expect someone at Access does, but it's not of much help if they aren't really participating in the forum..
I've had problems logging in to the official forum myself. I had the right password, but for some reason pushing the 'forgot password' button and renew the password made it all work again.
