I was surprised that there doesn't seem to be any intelligent harmonizer (e.g. key specific) midi plugins built into MainStage. I was wondering if there are any aftermarket plugins, or "Scripter" scripts people have made for intelligent harmonization.
One can hack the "Chord Trigger" plugin by using the "multi" option. But you have to assign each note separately, and that would take forever.

Transposer MIDI plug-in The Transposer MIDI plug-in can transpose incoming MIDI notes in real time and can correct notes to a selected scale. Transposer parameters • Transpose slider: Drag to transpose incoming MIDI Notes by ± 24 semitones. • Root pop-up menu: Choose the root note for the scale. • Scale pop-up menu: Choose one of several preset scales or create your own custom scale (User) with the onscreen keyboard. • Keyboard: Click notes on the Keyboard to switch them on or off. Notes that are turned off are excluded from the User scale.

Okay, now I feel ALL KINDS of stupid, how did I miss that? HOW?!
I do sorta wish they made a "harmonize" toggle so that it would keep the original note as well. But in my particular case, I'm controlling a mono synth with portamento, so I want two instances anyway. Easy enough to copy an instance and transpose one.
Intelligent Midi Harmonizer plugin/script?
