I want to create a patch that will take an input midi note and output that note plus another note X above \ below the original (essentially a super simple way of creating chords).
So far I've only ever written patches that take one midi note in at a time and output one midi note at a time. To output multiple notes (as though the player was holding down more than one key) is it as simple as having two midi/out/note objects that are sent different notes at the same time?
