Well, I think I found the answer: in Logic's MIDI inputs page in Settings there are inputs for KONTROL S88 MK3 Main, KONTROL S88 MK3 DAW, KONTROL S88 MK3 Ext, and KONTROL S88 MK3 MIDI 2.0. (I had set both Logic and the S88 for MIDI 2.0 mode, as I'm very interested in using the bi-directional capability of MIDI 2.0 to update controllers, hopefully making it easier to tweak controller info on a track.)
It turns out that if you have the S88 Main input and the S88 MIDI 2.0 input both active, you get double transmission of controller data, though there's no double transmission of note data. If you deactivate the Main input you can't transmit anything, including MIDI notes, to Logic. And if you deactivate MIDI 2.0, you obviously won't have that. So the upshot is that MIDI 2.0 isn't quite ready for prime time on the S88 unless you don't mind having duplicate controller information. Hopefully this will be corrected in a future update.
Can't you just turn off main in Logic and leave MIDI 2.0 active?
No, you lose all ability to send note data and also DAW control. It's kinda hard to understand what turning on MIDI 2.0 does at this point.n
That's a good tip! It definitely doesn't like both, I've had nothing but constant crashes with Logic. But it seems like if you disable at least one it works perfect.
This worked for me, I can still control the DAW, and control the plugin. Nice!!
Interesting. Thanks for this. I'm gonna go back in and see if there's something else I'm doing that's making it lose connection when I disable the "Main" input.
So I disabled the Main MIDI input and enabled the MIDI 2.0 input, then rebooted the keyboard and the computer. This time the keyboard could send MIDI note and controller information, but the DAW control was still lost until I re-enabled the Main input.
Another thing I'm still not clear on: sometimes the nob on the keyboard moves the playhead and other times it controls the fader level on the currently selected track. I'm not consciously changing anything, and I don't know how to make it switch between those two behaviors. Am I missing something?
I recall having to do something with Audio MIDI Setup on Mac to get 2.0 to work. For me if I switch the keyboard back to regular MIDI then it breaks things and the keyboard doesn't MIDI any more.
Yeah, as I recall, when switching the keyboard to MIDI 2.0 mode it instructed me to delete the S88 entry in Audio MIDI setup and reboot the keyboard, which then created a new Audio MIDI entry with MIDI 2.0 enabled.
