Logic 8.02 Mac Pro TDM Digi 96 i/0 OSX 10.5.5 - HEEELP!!!

Yeah . . wow . . it's pathetic how they've abandoned TDM users!
I've been working professionally with Logic on Digi hardware for 12 years,
and have had nothing but problems the last year.
Can't go Native because of too many open projects and lack of backwards comp,
but it sure is tempting sometimes. .

So, out of all Logic users, we are the only ones still using TDM? 🙂

Does DAE / CoreAudio work well for you?

*Hi Dane. Great thanks for helping us!*

I'll answer your q's

+With the Magma, do you still keep 1 Core card in the host computer?(with HD3 i have all cards inside my mac.)+

Only Magma-card in computer (since it's PCI-Express) and all the (4) PT-cards (including core) in Magma. I have 1 HD Core, 1 HD Accel, 2 HD Process. All checks out "passed"

+Are you running SpotLight?(I have mine turned on on the main OS X HD, ad off on my Recording/Audio/Logic&Pro Tools Sessions.)+

Tried both.

+Are you using a dedicated, separate (from the OS) HD for ALL Recording/Audio/Logic&Pro Tools Sessions?+

Yes.

+Have you tried removing ALL plugins from there normally kept folders, and booted? Keeping the plugins in a folder on your desktop? to see if they are interfering..+

Yes. In addition, I've made 2 separate fresh Leopard PTLogic installations on 2 separate HD's, to be able to try different things . .

+Read this it helped me understand what is happening technically.+

Ok. I actually glanced at it . . but I'll read it again, thoroughly!

+Have you read though a followed the Logic Pro 8 TDM Guide located here and in your Logic app?+
+ http://manuals.info.apple.com/en/LogicPro_8_TDMGuide.pdf+

Yes. Very uninformative indeed. I must say, having been a Mac-freak since early '90s, Apple's support and documentation on possible and reported problems really *****. It feels like the TDM-crowd was abandoned the minute Apple bought Logic.

+Simple, but is you Logic Pro working fine with only Core Audio running? (no DAE & DTDM)+

Yes.

No. At the moment, I'm even using DAE exclusively (no DTDM) which seems to help reducing the horrible lag (even moving the pointer is slow when having DAE+DTDM active) and I do get some "sound" from EXS .. but only that horrible digital noise/distortion . . you know, the kind you sometimes get from DTDM-instruments on a working setup, but can be helped with different tricks . .

This noise/dist is way more though . . and alternates with silence . . a few seconds of noise to be followed by a few seconds of in-responsiveness . . and back . .

Graphics show that the whole system is having a tough time to . . with jerky indicators.

It seems like with:
DAE/DTDM active = Whole computer slow, no sound from anything but DAE Audio-channels.
Only DAE active = Computer faster (still graphic-jerks) and some noise/dist from AuxEXS

Affirmative!

Important note:

I forgot to mention that everything (or close to) is working fine under 10.4.11
It took months to make anything work on an Intel, and I waited until 2 months ago to try and move ahead to Leopard, which clearly isn't working yet.

Fun fact:

When running DAE/DTDM under Leopard, computer slows 99%. Can't even pull off to get a sample of the running code from Activity Monitor.

Interesting - you have the newer model . . hmm . . could that be the difference?
