Sythesizer noteOn() receives wrong MIDI note (127)

Running across this issue during fast playing of notes, Sythesizer noteOn() seems to be occasionally receiving note 127, which was never played because it’s out of key range, under the AudioPluginHost, but also LogicX. I can filter this event out for my app, but technically 127 is a valid note. Wondering what the best way is to handle these anomalies.

Thanks,
