MOTU: direct hardware playthrough unavailable w/ PCI324 in OSX?

Bob Ross · 14th December 2005

I have encountered what may turn out to be one of those annoying "features" of a recent software upgrade that may force me to have to upgrade some hardware, wondering if any Digital Performer users can confirm.

I've got an original ("Mark I") MOTU 2408 with the PCI-324 card in a G4. I finally took the plunge and updated to OSX (Panther 10.3.9) and simultaneously upgraded DP from 3.11 to 4.62.

And now it appears that the option to select "Direct Hardware Playthrough" in the Input Monitoring Mode dialog box is no longer available to me! Someone on the Unicornation board suggested this was because Direct Hardware Playthrough is not available on the PCI-324 card when running OSX. Presumably I would have to upgrade to a PCI-424 card to regain this capability?

Can anyone confirm this? (I've asked MOTU tech support, so they should be getting back to me sometime next summer.)

Thanks.
