Hi folks. I decided to test upgrading Omnisphere 2 to Omnisphere 3 using some existing test Omnisphere racks which were built with Omnisphere 2.
I can see that the Multis loaded fine (Cantabile seemed to replace the VST fine) but I cannot play the instruments as I’m getting this “0 Input Event Bus” as the MIDI Destination. For the life of me I can’t figure out how to get MIDI to the instance of Omnisphere.
If I load up a fresh instance of Omnisphere I see the MID route as expected (e.g. Omnisphere 1 - MIDI In)
I can work around my saving the multi, replacing the plugin with Omnisphere VST3 again and then loading the Multi but I find this a bit of a worry when I do this on my live laptop.
Anyone have any ideas what this “0 Input Event Bus” is and if there is anyway I can fix the MIDI route?
EDIT: I should probably add when I play a note I see the MIDI In activity flash green on Omnisphere as the image below shows BUT if I use the MIDI Monitor on the Omnisphere I only see this “O Input Event Bus” and no note information (or anything else for that matter e.g. tested with a Program Change too)
