I was excited to read the initial reports of DP7, and it seemed that MOTU may have done what I was hoping for: stabilize the app as much as possible. Unfortunately, DP7 is less stable in my workflow than 6 ever was. And that is pretty bad.
The most glaring problem I have found is detailed here:
http://www.motunation.com/forum/viewtop ... =1&t=38254
In a nutshell, DP7 is totally unstable when I set up VI's to route through bussed outputs. I have easily reproduced this in three different operating systems and two completely separate Intel Macs: 10.4.11, 10.5.8, and 10.6.1 (actually
four if you count 10.6.0). I keep hoping someone will see a problem with my methodology for testing this, but it is pretty simple routing. This looks like a serious bug to me, and renders DP7 unusable in my studio.
The other thing I was hoping DP7 would address was the Eucon processor utilization issue. DP7's CPU meter
still freaks out when Eucon is enabled in a session that contains lots of tracks (like a large orchestral template with many blank MIDI tracks). I was prepared to live with this one, I prefer to mix as a completely separate phase, and don't really need the Euphonix controllers when composing. But it's still a black mark.
The first issue is the deal breaker for me. As much as I would prefer to work in DP, I need to go back to Logic (again) until this is sorted out.

And I
can't stand Logic. DP is so much better in so many ways, and actually has fewer of the little buggy annoyances that Logic is full of. But Logic doesn't crash, so back I go for now.
I'll be right back with DP if a fix for this problem is made available, but I won't be buying any more upgrades until I see for myself that DP is rock solid.
