Alpha Juno Control 1.0

Alpha Juno Control is a small utility app that will let owners of Roland’s Alpha Juno keyboard control patch parameters via MIDI from their Mac.
The app can be used with any DAW or just on its own. Once you launch the app, set the MIDI Out destination and MIDI Channel to correspond with your Alpha Juno.
When you move the sliders, the Juno sends the appropriate SYSEX commands that the Juno expects to change its parameters like CutOff, Resonance, etc.
