I have just migrated from my old iMac running High Sierra to a new iMac running Catalina 10.15.7 with Intel Core i5. I loaded Melodyne in to a vocal track in Studio One 5 Artist, the Melodyne window appears but the audio blobs are not showing. I'm using Melodyne 5 essentail 5.1.1.003. I can load the standalone version and can import a vocal track in to it and it works ok.
This problem did not exist on my previous iMac where I was using the same version of Studio One 5 and Melodyne. My old iMac had 12gb of memory, the new one has 8gb and I'm awaiting extra memory to arrive.
Any ideas why Melodyne is not working in Studio One?
Many thanks if you can help
