Is anyone having AU validation issues with Steinberg’s TheGrand3 virtual instrument and Logic Pro X 10.3.1?
When validation succeeds, the instrument seems to work OK.
When validation fails, I get a dialog box that says:
Failed to load Audio Unit “The Grand 3”, please contact the manufacturer
for an updated version or further assistance.
Whether validation succeeds or fails sometimes varies around whether the project is being opened vs re-opened.
Going into plugin manager and validating the plugin manually, it usually passes. Except when it doesn’t.
FWIW, my TheGrand3 plugin is fully up-to-date with all patches available applied.
