Hi all …
Thanks for your comments.
This appears to be nothing to do with WL.
It looks like … somehow … the big Windoze update re-set my RME card buffer to 256. It has NEVER been 256 since it was installed. I only picked this up because we were looking at the all settings methodically to try and isolate the likely culprit.
A quick re-set to the correct buffer size for the system and all is rock solid once more.
I should know the answer to this, but I have never had to contemplate it.
The reason: After the last update to 9.5.4, I have for the first time ever experienced instability. A track is playing and it suddenly stops and WL disappears from the screen. Any sample rate with or without plugins.Apart from a new mouse and a Windoze 10 update, the only thing changed in the system is the WL upgrade.
In all the past versions of WL, this is the first time I have ever encountered instability. 9.5 in particular has been rock solid until this.
