Subject: [PATCH] fix: panic on connect to input

Upon inspection, it appears the received message will continuously send a single byte `11110000` when no keys are pressed. The length of this value is 1 byte. Not sure what this means or how MIDI works, but checking that
the input length is equal to 3 fixes this problem.
