Sustain pedal doesn't work in Logic

My sustain pedal doesn’t sustain (I lift my hand from playing a chord with the pedal down the chord stops). I’m at my wit’s end trying to figure out what the problem is.  

My setup:

• Logic Pro 11.0.1
• Intel MacBook Pro
• Akai MPK249 Keyboard Controller

So far I have

• Rebooted my computer
• Swapped out the.pedal
• Reversed polarity on the pedal
• Swapped out the keyboard with a Launchkey49
• Confirmed Logic is receiving CC64 when I press the pedal
• Selected “Bypass all Control Surfaces”
• Deleted and reinstalled Control Surfaces
• Deleted ~/Library/Preferences/com.apple.logic.pro.ca
• Ensured I don't have any filters set in "Project Settings / Midi / Input Filter
• Tried it it MainStage - still no sustain, but I can see the pedal graphic blink as I press the pedal

Nothing has worked.  Does anyone have any idea why my sustain pedal won’t sustain?
