noteBuffer = {}
-- Print all notes in the note buffer.
function printNoteBuffer()
for note, velocity in pairs(noteBuffer) do
print("Note# = "..note..", Velocity = "..velocity)
end
print()
end
-- Write notes to the buffer and print them.
function onNote(event)
postEvent(event)
noteBuffer[event.note] = event.velocity
printNoteBuffer()
end
-- Remove notes from the buffer and print the remaining ones.
function onRelease(event)
postEvent(event)
noteBuffer[event.note] = nil
printNoteBuffer()
end
