Cubase Elements 10 transport freezes briefly

When playing back a song, the transport will stutter and drop off sound (I can see the mixer meters falling.) In a fraction of a second playback resumes until the next freeze. The time between freezes vary, but once it starts it won’t stop. If I happen to be recording a midi track, and the stutter happens, the recording stops and I am back in just playback mode.

i thought it might be the buffer size, nope. Thought it might be a certain VST or instrument, don’t think so.

Any help greatly appreciated. Been having this intermittent problem for about a month.

Hi,

Try to increase your Audio Device Buffer Size, please.

I’m up to 384, and still having an issue. I’ve tried changing VST’s, eliminating VST’s but the problem persists. The longer I have Cubase open the worse the issue gets. I’ve also closed as many background applications running as well.

Hi,

Could you test your system by using LatencyMon utility, please?

Report from LatencyMon
Seems I have at least one problem.


CONCLUSION


Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

MEASURED INTERRUPT TO USER PROCESS LATENCIES


The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

REPORTED HARD PAGEFAULTS


Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

I have the same problem but I havent run the test yet. This problem exists on ly in cubase 10 not in cubase 5. So how is it possible to use the same vst, laptop and souncard the same tracks and wavs and have the issue only in cubase 10 not in 5?

The software found no problem but I have the same issues…steinberg? Wasted money?

CONCLUSION


Your system appears to be suitable for handling real-time audio and other tasks without dropouts.
LatencyMon has been analyzing your system for 0:06:47 (h:mm:ss) on all processors.

I increased the RAM in my PC. It has been the best investment with regards to performance. I have the MAX memory my PC will support. Everything runs better and Cubase doesn’t take any time outs during playback.
