Garageband recognising both key up and key down on MIDI controller

I recently upgraded from Venture to Sonoma and now my MIDI keyboard is registering both on key down and key up in Garageband (10.4.9). A few other observations that seem odd: - Garageband now says 3 inputs are connected when I connect the keyboard. However, in the audio tab, it only shows one controller. When I disconnect it says 1 is connected (but the settings say nothing is connected) - the pedal no longer works - things are working as expected in another DAW (Logic Pro) - in the Audio Midi Setup screen for the OS, only key ups are registering (not sure what was happening on Ventura) I have tried resetting the drivers but no luck. Anyone have any troubleshooting tips/ideas what may be going on?
