Hey people,
when I connect my MIDIbox-Keyboard (KB-app, not NG) to my MacBook and boot the MacBook, the keyboard sends weird informations like note Off instead of note-on. If I switch off the MIDIbox and start it again after the OS has booted, it works perfectly. Do you have any ideas what is causing this issue? The fastboot-setting doesn’t change anything…
Thanks,
Chris
I thought it may have something to do with the USB power. But I added a converter, so that 5V is safely provided at any time… the issue is the same…
Hello
Any app launched at macbook startup ? like audio/midi sequencer, DAW, or any midi driver/remote software, possibly sending midi data for initialisation on a studio setup that might confuse your midibox hardware configuration ?

No, nothing! Also it doesn’t depend on which macbook I use… I have some of them here of other productions. Didn’t test with a windows notebook yet.
If I use a USB-power-supply to boot up the midibox, it works… so this is kind of weird and I don’t know where to look at…
Another problem occured: I updated my MacBook to Sierra. Now the computer needs 10-12min for boot with the MIDIbox connected. If I disconnect it, it boots much faster. Also if I’m in the OS, disconnect the MIDIbox a reconnect it again, the keyboard will not be recognized anymore till next boot…
Damn!!
Lots of data being sent?
How about if you load the default NG program with no customisation?
It runs KB and not NG.
Right, but as a test, why not try booting NG to see if it’s something weird with KB or customisation?
Or are these rare problems with Mac MIDI drivers?
Okay, I did some checking.
The problem with the booting times and the connection-problem is gone if I set single_usb to 0 in the bootloader. So with 4 USB ports the Macbook boots up normally and I can connect and disconnect the midibox without any problems.
But regarding the topic-problem: This occurs only on KB. NG works fine (as far as I checked it yet). I don’t think it’s a mac-midi-problem, because I can see it clearly if I open MIOS Studio, that if I press down a key, it sends “(optimized)” and if I release the key it sends the note with the value… so it’s working in reverse till I restart the midibox after OS-boot.
