I thought it would be cool to have a place where everyone can share their experiences with Maschine in Catalina as well as other NI products, what works and what doesn't, perhaps also other popular 3rd party stuff commonly used in Maschine/KK. Keep in mind that the official statement for now is: Native Instruments software and hardware products are not supported under macOS 10.15 yet. For more info, please go HERE! So.. Update at your own risk, I have dual boot so I can go back and forth between Mojave and Catalina. I did a clean install of the OS so it's a work in progress, so far: Maschine - ✔ works. (tested Mk3 and Mikro Mk3) Komplete Kontrol - ✔ works. (tested M32 and KKS49 Mk2) Komplete Audio 2 - ✔ works. Kontakt/Reaktor V6 - ✔ works. Native Access - ✘ Mostly works but crashes sometimes, a couple of installs result in an error "An unknown error occurred" very descriptive as always... I cant install Kontakt or Reaktor correctly. A bunch of instrument updates show up immediately after locating my libraries, all the changelogs are empty, also typical. Kontakt 5 - ✔✘ Mostly works - NA installation fails but the standalone app and the plugins are indeed installed, it asks for the license a every lanch tho. Reaktor 5 - ✘ Does not work - NA installation fails, as Kontakt5 it does show up as an app/plugin but the authorize process says it can't find Service Center, my guess is SC was 32bit so anything that depends on it can fail. A bunch of instrument installs fail, especially the big ones above 20GB, it takes multiple tries until it eventually is actually installed but I still get an "unknown error" and NA thinks it's not installed, reopening NA and using the "Locate" feature fixes it. This whole process reminded me of how much NA still feels like a Beta app even though it was released ages ago, its already buggy in Mojave so Catalina just makes it a tiny bit worst. I had to manually point every library sub-folder when relocating all of the K12UCE libraries, NA cant simply scan the folder where all my libs are (it's defined in the preferences) and locate them all by itself... it literally took me 30min of clicking, a PITA beyond belief. Other than NA I am pretty surprised at how well everything is working so far. Other software: Ableton Live 10 and beta - ✔ Cubase (9 Artist) - ✔ Logic Pro X - ✔ Serato Sample - ✔ (even though the website says it's not compatible), Waves plugins, Fab Filters, Melodyne, and all the 3rd party plugins I installed so far work fine, both in Maschine and my DAW's. Reason - haven't tried it yet but it already had issues in Mojave that were never fixed for my version (9.5) so I doubt it works correctly. Sort of related: How does iPad's sidecar work for with Maschine/KK? Did anyone try it yet? Very curious about this.
