I couldn’t use the search function in several U-He plugins. Their tech support told me to check the permissions of dialog files in the Home/.u-he folder.
So, for Diva, I looked in ~/.u-he/Diva for dialog, dialog.32, and dialog.64. I had to set the permissions to world executable.
From the terminal, I typed:
chmod 755 dialog
chmod 755 dialog.32
chmod 755 dialog.64
That made the search functions work!
YMMV, but it worked for me in Reaper.
