I have a Mark of the Unicorn (MOTU) 2408 MkII and a 2408 Mk3 connected to a PCI-424 card and am trying to get both of them to show up in Sonar Platinum.  So far I can only see the MkII unit.  Does anyone have two MOTU units (2408s or other models) working simultaneously in Sonar X1, 2, 3 or platinum?

What driver mode are you using? If it's ASIO,  then , like The Highlander, there can be only one.  Try using WDM mode.

Yes, you can have two MOTU audio interfaces showing up (using ASIO) if they're both plugged into the same PCI-424 card.    I use a 2408 Mk3 and a 24IO into a single PCI-424 card.

Thank you gentlemen for the replies.  I found a support document at MOTU:

It turns out I didn't have the MK3 enabled in the MOTU PCI audio setup only the MKII.  Once I enabled it, they both showed up in Sonar.  Now All I have to figure out is how to get my MOTIF XS rack unit firewire interface to show up in audio and midi devices.  Thank you again.

So now I'm wondering if what is keeping my Motif xs firewire audio device from showing up in Sonar is this one ASIO device rule. I think I'll switch the PCI-424 to wdm and see what happens.

Well that didn't work. Still no motif firewire audio device present in Sonar even with wdm drivers

Yes...will work. But not sure why it would not be showing up.

Well I am back to ASIO drivers on my two MOTU 2408's and all is good there.  No matter what I do with the firewire/Yamaha MOTIF XS Rack interface it doesn't show up in Sonar even though it shows up in windows.  So, I'm just going to use the Motif USB jack for it's MIDI connections and the MOTIF analog outs into my MOTU Mk3  I've wasted enough time with the MOTIF firewire interface when I could be making music.  If anyone out there who has the MOTIF firewire interface working in Sonar reads this post, let me know how you made it work and thanks in advance.
