Hi,
I've recently built a simple midi controller that I want to use in Logic X, but I'm having some problems. If I use the controller in Ableton, it seems to work fine, but as soon as I try to use it in Logic, it registers briefly on the midi input in Logic, but then disconnects. If I then go back to Ableton it's still disconnected. Once I unplug and plug in again it works as normal in Ableton, but I get the same issue in Logic. I've put the code I've used below. Sorry if there's some glaringly obvious mistake in there, very new to this! Quite the learning curve.
If anyone could offer any help it would be massively appreciated.
Thanks!
