I’m trying to use the VST3 plugin from OB-Xd - Oberheim Inspired Synth | discoDSP in a Midi track, but the status of the plugin after scan is “Error”. I’m running Ardour 9 (also tested with 8.10.0). I’ve confirmed that Ardour is 64 bit and the plugin is 64 bit, and I get the following log, which states that “Scan failed”, but I’m not sure where to look to triage this. I tried clearing caches and re-scanning, but I get the same issue every time.
Thanks,
Derek
