Alpha Juno Control
What is Alpha Juno Control?
I’ve love the sounds in my Alpha Juno but I’ve always thought that editing the sounds was a bit of a pain. The LCD and "Alpha Dial" leaves a lot to be desired in terms of quick (and fun) editing. So I developed Alpha Juno Control. It is a small utility app that will let owners of Roland’s Alpha Juno keyboard control patch parameters via MIDI from their Mac. Think of it as a software version of the PG300.
How does it work?
Alpha Juno Control is a stand alone app that 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 it’s parameters like CutOff, Resonance, etc…
Does it support MIDI Learn?
Yes. Right-click (or Control-click) any of the sliders to put the app into MIDI Learn Mode. While in MIDI Learn Mode, it will listen for any incoming control change message and assign the controller number to that particular slider.
Can I use it with my MKS-50?
Yes. The Alpha Juno series and the MKS-50 share the same functionality (MIDI-wise).
Setting up your Juno
Important Note: You must enable your Alpha Juno to receive system exclusive messages. This can be done as follows:
- Press the MIDI button six times until the LED reads: MIDI EXCL: OFF
- Rotate the alpha dial until the LED reads: MIDI EXCL: ON
- Save this setting. Press and hold WRITE, then press MIDI again.
