Required Settings on the Synthesizer

You will need to perform these steps on the hardware synthesizer to be able to properly communicate bi-directionally between the Synthesizer and the Editor.

On the Alpha JUNO
1. Turn the Memory Protection switch to the 'Off' position to be able to store programs from the Editor.
2. Push the 'MIDI' button, and set the 'MIDI Exclusive', 'MIDI Volume', MIDI Bender', 'MIDI Aftertouch', 'MIDI Portamento' values to 'On'. Set the 'MIDI Channel' value to '1', or your preferred MIDI channel. Write these settings to memory using Write + MIDI buttons, then MIDI button to store.
3. See the MIDI Implementation Chart for Mapped MIDI CC messages for each parameter. Yep, we mapped them! :)

Using The Graphical User Interface

The graphical user interface of the VST-AU Alpha JUNO Editor is designed for maximum ease of use, giving you easy access to all of the parameters right on one screen. You are also able to rename, modify and browse the Patches right inside the Editor itself. All controls are handled via either a slider, knob, combo box, button or text edit box.

Some hosts do not allow plug-ins to use keystrokes on the main plug-in window. You can still use the Patch Manager to rename the Patch in this case.

Use the Mouse Scroll Wheel to increment slider and knob movements in single increments.

Double-click a slider or knob to set it to 'middle' position.

Use the arrow buttons on your keyboard to move up and down on combo boxes.
