    I am using a MIDI to USB adapter to connect a Yamaha P-155 Keyboard to a Macbook laptop. The adapter works in Garageband and Synthesia. The sustain pedal on the keyboard is not working properly with this setup. Instead of sustaining the notes, when I depress the pedal it plays a note by itself. I don't have experience with MIDI so am clueless as to what is happening. Any help is appreciated. Thank you.
