DP 9.1 loses clock

[David Polich]

At least I think this is what is happening...intermittently. Yesterday I had several instances of
the audio from DP becoming distorted and garbled...all audio. Resetting the buffer in the control panel would fix it. A couple of times recorded MIDI tracks were playing back late as well - and resetting the buffer fixed this too.

Anyone else experience this problem?

I have a similar problem which I reported to MOTU, but they couldn't reproduce. It's a loss of sync (or buffer overflow or sumthin) when using the built-in digital I/O on my Mac Pro. Resetting the buffer fixes it for a couple of minutes, then it returns. My other interfaces work fine. And it only happens in 9.1. - 9.02 is still working fine (so I know it's not the Mac).

I don't know if it is related, but DP is now used as the "movie window" for Finale 25. (I know... W T F!) The connection, via Rewire, is lost within a minute and the "system" doesn't work. Restarting Finale seems to reconnect, so DP is probably working ok. I just thought I'd mention it.

[Phil O]

What happens if you don't have DP? Will Finale use Quicktime?

The similarity is that the problem develops after a minute or so, can be fixed but then re-appears after another minute or so.

How about your problem, David? Does it have a similar reappearance after fixing it (1 to 2 minutes)?

Any DAW will do. I had lunch with Craig Marks last week who suggested video slave. I'll be checking that out today.

Had this happen yesterday at someone else's studio. 2408 and a Yamaha digital board. Studio owner said he'd never had it happen before. Tried all sorts of things but changing the 2408 from optical clock to internal and then back again fixed it. Very weird. Wouldn't play and locating with the keypad would go to some random location.

With some sadness, I have gone back to 9.02.
I'll miss 9.1's latency reduction, launching more
quickly, and handling some VI's and plugs more
efficiently. The deal killer for me was actually
the sustain pedal problem, followed by the
CPU overload with "some" plugins and
this loss of clock or whatever it really is.

Looking forward to seeing "9.2 Update is out"
posted on this forum, for sure. And for the
record, I dont blame MOTU in any regard.
I know they are working to fix these issues,
many of which they could not have foreseen.

I'm glad that these things aren't happening on my rig. But I'm even more glad to see a post where a DP user reports a problem without going ballistic and accusing MOTU of screwing us all on purpose.

Over the last few days I've been having similar issues. The signal is getting to the DP mixing board, but no sound comes out. A message appears saying:

"Digital Performer is not receiving a clock signal from the audio hardware. Check to make sure hardware or peripheral settings are setup correctly or disable the audio hardware for MIDI playback only."

I thought maybe my 1224 was going bad, or the digital cable between the computer and the 1224 was going bad. But the fact that other people seem to be having the same or similar problems suggests that there's some sort of bug in DP 9.1. I hope it gets resolved soon.

How can a DAW loss contact with a clock and not the converters if both are one and the same

It could just be an erroneous error message.

It may be there is no error generated to the end user for converter issues since that's more of a transparent aspect. If the clocking goes south you know immediately. Then again, the programmers may see the converter and clock error message as a redundancy.

A couple of other things happen during these 'loss of clock signal' events in addition to (1) getting no sound, (2) the mixing board showing signal coming through, and (3) no activity showing on the 1224 front panel meters:

-- The transport controls don't move when play-activated, despite the fact that, according to the mixing board fader activity, the piece is actually playing (although silently).

-- No sound is produced when playing a note on the MIDI keyboard through a record-enabled MIDI track.

When this has happened, I've tried various methods to get the system working again, including turning the 1224 off and back on, quitting and rebooting DP, restarting the computer, and shutting down and restarting the computer. Though the results aren't consistent, one of these methods eventually works.

I ran a disk and permissions repair last night and will see if it made any difference.

What I find irritating is the inability to read the crash reports any more. One could learn a lot from those.

Now I'm worried.

I have several critical sessions in the upcoming week.
I've switched over to 9.1.

Would I best be advised to revert to a prior version?

Thanks!
