I’ve just put up an unofficial build 4201:
To help diagnose this and to confirm I’m on the correct path in narrowing this down I’ve added a new setting in Tools → Options → Diagnostics, called “Slow VST3 Buffer Prep”. This is a temporary setting that will be removed once the issue is resolved.
- When enabled, it reverts the behaviour to that of 4196.
- When disabled, the functionality is the same as 4200.
I’m interested to hear from anyone who’s having issues with 4197 and later whether toggling this setting makes any difference.
