I'm on Mojave 10.14.6 on my 2015 MacBook Pro. Logic Pro X 10.4.6
The problem I'm having: In Logic Pro, the midi is very delayed, and when it does work, only one note sounds. I've tested midi instruments in MainStage, and they work fine.
This just started today, so apparently I toggled something that is causing this. If I "Reset All Midi Drivers (from Preferences > Midi) and play my keyboard while this is happening, midi will return to normal and play. But as soon as the reset is completed, it goes back to only playing one note at a time (or possibly two simultaneously) and then long delays.
If midi is already recorded (or input by mouse) then it will playback just fine.
Any ideas what I may have done?
Thanks!
