Hello again on this topic,
We have 9 Nuendo 7 licenses and have just started updating the computers from v5.5.6. We have identified an issue during recording - on rare occasions Nuendo 7 will engage in excessive audio file reading while recording resulting in record failure. This is into sessions where there should be no audio file reading. The only workaround is to quit Nuendo and relaunch, not workable in live television broadcast. This has persisted through 5 or 6 drive wipes and MacOS10.10.x and 10.12.x. Details can be found in the other Mac N7 drive thread. This also occurs to a much lesser degree, although more frequently, with Nuendo 6.5.
This weekend an associate wrote an Automator script that engaged record in Nuendo, let it run for a few minutes, disengaged record, waited for files to update, then engaged record again. This ran through 130 cycles, on the 131st cycle Nuendo exhibited the excessive read problem.
With Nuendo in “failure mode” he grabbed the following -
- A screenshot of Activity Monitor showing the Nuendo disk read quantity (should be far less) and multiple Nuendo failed records.
- A text dump of an iosnoop capture showing it was actually Nuendo reading the actual audio files during the recording; this is different than the limited reading when closing files after recording.
- A screen recording of Nuendo failing recording with the diag screens visible to illustrate Activity Monitor and dtrace. During the previous testing the screen capture was not running. Quicktime indicates i/o activity due to the screen capture.
Enclosed is a zip file containing the first two items, the screen recording is too large.
I’ve continued the support case with Steinberg, I’m hoping with this additional corroboration they can come up with some answers. I hate to be stuck permanently at v5.5.6 for acquisition, the OS is too old.

Thanks for listening and hope to continue using Nuendo in live television,
