Help needed - Monologue and OSX 11.5.2 Big Sur

[oliespink]

Hi, I am in desperate need of some help and advice please.
As the Subject suggests i am running OSX 11.5.2 and I am experiencing odd behaviour with Librarian and my Monologue.

I have had to uninstall the Korg USB drivers as they did not work with this version of OSX. The synth works fine in logic I am able to record Midi no problem and play back is fine. In Librarian tho its hit or miss if it picks up the Synth, I get MIDI message is broken when trying to Receive, Some times the sounds will change when selecting in Librarian and sometimes it won't. I have tried different USB leads and ports and it behaves the same.

I have looked on Korg Website under monologue downloads and there is nothing to download apart from a text file and pdf.
I only have the old updater and its 32bit so won't load. It seems I am now stuck with a synth that cant update or communicate with my Mac. Whats should i do ?
Many thank
