You are not alone. And this is for sure an Apple issue, not Digi - there is an announcement about it on the Digi website on the compatibility page. Here is the text from Digi: > Although Logic Pro 7.2 is a universal version that runs natively on > both Intel- and PowerPC-based Mac systems, Logic Pro 7.2 is not yet > compatible in DAE mode with Pro Tools HD 7.2.1 for Intel-based Mac > Pro systems. > In order to use Logic Pro with Digidesign hardware on Intel-based > Macs, the Digidesign CoreAudio Driver must be used instead of DAE > mode in Logic. > Logic Pro will require a future update from Apple to support Pro > Tools HD DAE for Intel-based Macs. I've done a bunch of research on this and after a lot of digging got some info from insiders at Apple. Apple does not offer a specific date for fixing this bug, but they are very aware of it and consider it important. My contact told me that their goal is to have it fixed before NAMM (mid-January), because they don't want a bunch of angry users thronging their booth at NAMM while they try and sell their new versions. Even better, he said that while 7.2.3 definitely does NOT work with TDM on the Mac Pro, some users have found a way to get it to work. The workaround is to uninstall Lotic 7.2.3 and then install Logic 7.2.0 or 7.2.1 but not to update past version 7.2.1. Those earlier versions may work with TDM. (Make sure to instal Pro Tools 7.2.1 first.) Those earlier versions of Logic only use 2 of the 4 CPU cores in the Mac Pro. When Apple "fixed" Logic to use all 4 of the dual intel duo cores, the TDM functionality was broken. So it may work, but the native side will be hobbled a bit by only having two cores to work with. Still, that's way better than no TDM! I have not tested this yet - am planning to give it a go in the next few days and will report the results. Meanwhile, if anyone else tries this, please report the results here! - Dave On Dec 4, 2006, at 2:55 PM, Richard Bull wrote: > Message posted by Richard Bull <higherground@btinternet.com>: > > No, you're not the only one and I'm totally with you on this.
