USB Midi connection issue
Hello fellow audiobussers,
I have a funny issue with iPad Air 2 latest iOS and midi gear. As well with my MPK 225 MIDI controller and my newest addition on the euro rack case; HP 2 MIDI.
When I try to connect the iPad doesn't recognise the USB MIDI stuff in AUM or e.g. patterning only if I hook up a few times with the CCK (without power, the first one), put a powered USB hub in between and disconnect between the CCK and the out of the USB hub.
In the end the iPad suddenly pops up the 2 HP and midi controller in the MIDI matrix in AUM.
after that I can disconnect and connect the stuff with a time pause as much as I like untill I reboot the iPad for example.
The question is why is this happening? The stuff hooks up to reason 7 without a question on my MBP.
I've read your need to connect the CCK first to your USB device BEFORE stick it up the iPad but it seems to be another issue and this is very frustrating.
Do I need the CCK with power instead?I
