It was working previously, even on the same version however I cleaned up my plugins and re-ran the plugin manager authentication which seems to have broken things.
I can’t use any version of the Digitakt plugin that isn’t mono or stereo, all the multi-output versions now pop up a message saying “failed to load, contact the manufacturer”.
I’ve since tried restarting and reinstalling Overbridge, but no luck.
[edit]: seems to be a known issue with Logic 10.5 and all 3rd party multi-output plugins. Is Elektron aware of the problem?
