I'm running VE Pro inside of DP7 on a Mac Pro 2.66 gHz Quad-core Intel with 9GB RAM on OS 10.5.8. I also have an Intel MacBook Pro 3.06 gHz with 4GB RAM on OS 10.6.1 running my appassionata strings and percussion, and a G5 PPC on 10.5.8 running my winds and brass (thanks VSL for the compatibility!). I've got some weird audio issues going on.
With only one track playing back, I'm getting massive audio glitches. By "glitch," I mean the kind that sounds almost as if my sample rate was set incorrectly (it's not) or my master clock was sending a bad clock (it's not).
What's even more weird is that when I stop the sequencer and play back from a bar that has no data in it (an empty bar), I will hear the exact same audio glitch with the notes that were previously sounding when I stopped the sequencer. Also, if I record-enable a MIDI track that exhibited the audio glitch on, I will hear the same glitch only on that track.
The only thing that will fix the situation is to go to the end of the note and let the sequencer send a note-off. (So, for instance, if I had a 7-bar held string note, I'd have to go to bar 7 and let the sequencer send the note-off command.)
I'm not sure if this is a VE issue or a DP issue. But at this point, VE Pro is basically unusable for me until someone posts an update.
