We have released a minor update to fix some MIDI issues, you can get it by running the Aerodrums Updater on Windows, or re-downloading the MIDI update on Mac ( http://aerodrums.com/aerodrums-mac-software-download/ )
Here is what it fixes:
-Aerodrums is now more economical when sending Continuous Controller messages for the hi-hat(s) openness. The previous rate was confusing some programs.
-There is now no need to go back to the MIDI screen to get output after each Aerodrums launch
We apologize if you have experienced these issues
