Topic: Digiface USB, ADA8200, unexpected drop-outs/jitter
Hello everybody :-)
I use the DF USB together with 4 ADA8200 Adat Interfaces (32 channels I/O) for mixing and recording our music, f.i. we use it or making the individual monitor mixes for the band members and record the single instruments.
From all the Inputs I take a selection of more less 20 mono signals which I grab in Ableton Live for further processing. I use them for doing real time live effects but also we use it for recording the instruments on a single track basis.
Here the problems come up:
While Ableton Live plays certain sequencer tracks with metronome-tracks along our songs we also record the single Tracks of the musicians. There not much tracks playing back, maybe at most 10 tracks playback and 20 recording. Processor/Disk usages are below 30% - very relaxed
The processor and disk usage is pretty low and the audio buffer has a "relaxed" size but anyhow sometime in the midst of playback and recording, the playback gets stuck, some noisy digital sound comes up, followed by a second of silence and than the play/rec goes ahead.
This behaviour is kind of non deterministic and may come after 15 Min or 2 hours, but it happens at least sometime in a rehearsal.
When I take a look at the ADAT/master/Slave settings from RME it seems to be stable - no errors displayed/ no flickering.
Here's what I tried so far:
- Set the DF to master and the ADA as slaves
- Set the ADATs as master (just one at a time) and the DF as Slave
- Changed the optical cables
Now I hope that anybody has some hints for me how to avoid these dropouts. My strong guess is that the source of evil is the Audio-Clock. As the DF is not used ADDA-Conversion itself I guess that the focus lies on the interfaces and they'd be better slaves?
Does anybody know a monitoring-SW for these usecases? Would be nice if I could find log-file where each sync-issues with the respective ADAT-Port would be logged. By this way I could dive deeper into system analysis.
Does anybody know if there is a way to use an external Clock or a some hidden settings? The DF on itself has no connector for WC..
Any suggestions are appreciated!!! The system could be so powerfull but the "drop out" issue is really annoying :-(
Thank you :-)
