Sounds like the streaming thread got suspended and never woken up again. You don't happen to have your samples on a external hard drive?

@d-healey Cubase 10

@Christoph-Hart the files do reside on a (internal) harddrive that is separate from my OS drive. Same drive that I keep all of my other sample libraries on, but I don't seem to have this issue with other samplers.
-
This actually seems to be happening in other situations as well, not just when the system is resting. Here's what happens when I export audio mixdown in Cubase:
not in real time
real time
This was on a completely different system. Streaming from SSD.
Here's what my buffer settings are set to in the samplers:
-
What happens if you deactivate streaming (set the preload size to -1)?
It might be possible that Cubase 10 doesn't wait for the streaming thread to fetch the data (if it calculates the audio as quickly as possible, it might be the case the the streaming thread can't keep up with it).
-
@Christoph-Hart I'll give that a test today. Thanks!
-
@Christoph-Hart Setting to -1 made the memory usage jump thru the roof... but setting the buffer and preload to 200,000 worked like a charm! I had no idea they need to be set so high?

@dustbro -1 = no disk streaming, so everything is loaded into RAM
-
200000 is about 5 seconds so you just don‘t hear the cutoff.
Is this also „solving“ the export issue?

It's gotten much better. Realtime export is still much more reliable, but non-realtime is considerably better. I'm gonna crank up the buffer more and see what happens.
-
I'm experiencing the same issue on export - the instrument plays fine but when I render from Ableton, I'm getting these drops in the audio. What's the best way to remedy this? I'd rather not set the preload to -1 because the samples I'm loading are quite heavy at times.

@tomekslesicki Increase the buffer and preload time. That worked for me

Alright, I try to come up with a proper solution. AFAIK there's an API call
isRenderingOffline()and if yes I can make the audio rendering stall until the streaming thread is ready. -
@Christoph-Hart ok, so would it be possible to add a script that would increase the preload and buffer during rendering and keep it lower for normal use? If so, how?
Thanks!
-
No, the proper solution is to query the host whether the rendering is being done in realtime and if it isn't, make the rendering wait until the streaming thread has fetched the samples.
Everything else is just shifting the point where it starts to break.

Ok! How can I do that?

...or is it something @Christoph-Hart has to do behind the scenes?

I take that to mean Christoph will implement a solution.

Is this safe to release a plugin like that? A user is having problems with the plugin's audio in the DAW.
Or is it safer to create a combobox in the GUI to increase the buffer and preload if they have problems?
