I'm running Mojave 10.14.6 on an iMac 3 GHz Intel Core i5. Latest version of Pro Tools. The S88 plays sound via MIDI / NI plugins in Pro Tools and Live. I have properly mapped the keyboard in Pro Tools: Setup-Peripherals-MIDI Controller-Komplete Kontrol.
I can activate Komplete Kontrol as a plug-in and "see" the selection in the S88 windows. However, I cannot use ANY onboard browser features. Nor can I assign any parameters. No buttons on the keyboard produce action except left side wheels.
A full week of "support" interactions, which for NI is like, every 48 hours to reply. I recently got put in touch with an LA rep over email; his solution--to trash the Pro Tools FB360 plugins and PT preferences--didn't work (I'd already tried that because not an idiot).
I'm sending back the device on Monday. This after NI didn't bother to tell S88 MKI users that the MacOS update a few years back would brick ALL features.
Posting here in a last ditch effort to see if anyone has a solution.
