Hmmm… Well, since there is NO MLAN driver available for the MR816, it would seem that you are out of luck. I can’t imagine why you’d want to use the 01x audio inputs, though, as there’s nothing special about them. It’s been so long since I had my 01x hooked up that I’ve forgotten most of what I knew about it. MLAN was such a cool idea, but it seems it never took off. I used mine together with an i88x to get the GOOD mike pres. COMPLEX setup is probably what killed it. You had to be an engineer to get it set up and working, but once you did, it was neat. Cubase saw the two-piece system as ONE input unit.
But, just thinking out loud, it seems like it would be cool if you could use the 01x as a control surface and handle the ASIO audio through the MR816. if Cubase would see it as a MIDI device even though the ASIO audio driver is pointed to the MR816, it seems like it might be possible, but that’s a BIG if. To find out, try this: In Cubase, with the Yamaha 1394 Windows driver running and the 01x connected, choose the generic ASIO driver and see if you can still see the 01x MIDI port and get it to work as a control surface.
I can’t imagine being stuck on Win XP, though. Also, since both of these units use a Yamaha 1394 driver, it would be interesting to see if they can both be recognized at the same time in Windows. Even if it is possible, you might be forced to use an early MR driver to get it working in XP.
Whatever, if you try this you’ll be on your own. NOBODY but a few tinkerers will be available to support you. ACHHH, so many headaches.
BTW, when I retired my 01x, Yamaha had a customer loyalty program in place that allowed my to buy my MR816 at half the retail price. Took a little of the sting out of the need to replace it due to the lack of Yamaha driver support. I doubt that it is still in place, though, as it was a long time ago. Wouldn’t hurt to try.
