If Midi Internal Messages "Don't Exist" then how can the Midi Local Off setting disable them?
Those two answers contradict each other.. Just saying..
As I understand it, the internal messages go to the onboard sound generator of a synth module but they are not sent out via MIDI and so are not actually MIDI signals. Local Off, would disable them and turn off the internal sounds. Thus, Internal Messages 'don't exist' as MIDI messages.
