I kid you not. And I throw all sorts of VIs at it, within a 400-track MIDI session, syncing to MTC, running QuickTime video, you name it. I whip around in the UI, relocate, do what you will, before, during, and after file saves. Stable as a rock.I only make this point in lieu of the fact that my colleague, who recently upgraded to the "latest and greatest" Mac Pro Intel 8-core, is experiencing increasingly more inexplicable crashes from DP 5 and DP 6 (which he reports to be more confusing and less reliable). It seems to be far more stable on PowerPC Macs.
The frustrating thing is that there are no clear answers or solutions to these seemingly elusive bugs and glitches that bring DP down left right and center. The suggestions in this thread are great, and I've noticed similar behavior from Performer. But what we really want is a FIX for these issues - issues other sequencers don't have to deal with. MOTU only has to deal with one platform - OSX, and typically one interface scheme - MOTU audio hardware. It's not like we're dealing with Windows and the umpteen billion hardware combinations.
In our case, DP 6 was a big disappointment. We've had to revert to 5.13 for a slew of reasons. So far, reducing the number of VIs has helped abate the crashes to a dull roar, but we're talking about 8 massive cores, with the cpu floating well below maxing out. Most of the crashes seem to occur after freak spikes of the CPU meter to 100% in the red. Perhaps it's certain VIs that are not Intel/Leopard friendly, or perhaps DP is just a piece of garbage. That's what we're trying to determine right now. But in heavy production cycles, who has time to waste days experimenting with adding/removing plugins, altering settings, and reinstalling software? That's exactly what our lovely friends at MOTU tech support are asking us to do.
