Known Issues

If there are no images visible, or previous version images are showing after installing a new version of this program:

MacOS ※ — delete folder Library/Preferences/Juno Alpha/ and restart program.
WINDOWS ※ — delete folder C:\Users\%USERNAME%\AppData\Roaming\Juno Alpha and restart program. @RD /S /Q “C:\Users\%USERNAME%\AppData\Roaming\Juno Alpha”
When saving custom cc ⇒ sysex mapping to file under Linux and MacOS be sure to add extension .JUMP to end of filename.
Workaround/Bug Fix :: To build as standalone executable on Windows or export as VST, please add 24 pixels to the panel height before exporting.. (otherwise you will find the bottom 24 pixels have been truncated).

DAW Setup

To create a VST or AU file:

Load the Ctrlr.dll (Ctrlr VST/AU) into your DAW
Load this panel into Ctrlr VST/AU instance.
Then go to File -> Export -> Export Restricted Instance. This will build a VST dll or AU (.component) file.
You can now load this panel independently of Ctrlr.
Or download pre built files from

Running as VST under Cubase

In Cubase, Disable †Midi-in **Midi-out ports to the “Juno Synth”.
Open Juno Alpha VST in an instrument track IN=(All Midi Inputs)
Create Midi track IN=(All Midi Inputs) OUT=(“Juno Synth” Midi-in) (I record midi notes & data to this track).
In the VST Ctrlr panel connect to the †Midi-in and **Midi-out ~ connected to “Juno Synth” (you disabled them in Cubase ( See step #1)).
I found the only Midi-thru setting that needs to be checked was MIDI→Midi Thru→”Plugin-host->Output Device” (The 5th option down in the fold out menu)
Engage Monitor on Both tracks.

Ctrlr – Connect your MIDI->Input/Output to the same in/out as on the JUNO.
Ctrlr – Connect MIDI->Controller MIDI to your MIDI Controller keyboard.
On your MIDI Controller keyboard assign a slider/knob to a cc # 0-127
In the Admin area of the panel, switch on cc mapping
Select which control on the panel you want to associate with the CC# you assigned on your hardware controller!

BULK DUMP/LOAD PROCEDURE

1) Connect MIDI OUT and MIDI IN cables between the Alpha Juno and the computer

2) Set the MEMORY PROTECT SWITCH on the back of the keyboard to the OFF position

3) Press [ MIDI ] and the display will read MIDI CH = #

4) Turn the Alpha-Dial until all of the settings look like this:

       MIDI CHANNEL= 1
       MIDI OMNI   = OFF
       MIDI LOCAL  = ON
       MIDI AFTER  = ON
       MIDI BENDER = ON
       MIDI EXCL   = ON
       MIDI HOLD   = ON
       MIDI PROG C = ON
       MIDI VOLUME = ON
       MIDI PORTA  = ON

5) The BULK DUMP data transfer methods used are different from the
   instructions listed in the Alpha Juno-1/2 Owner's Manual.

   You must press the WRITE key at the same time as the DATA TRANSFER and
   BULK DUMP keys are pressed.  

6) The method for BULK LOAD data transfer used in this
   manner should read in the Alpha Juno-1/2 display window as;
   Bulk Load MIDI.o                       <==== Correct
   as opposed to the normal display of:
   Bulk Load MIDI..                       <==== Incorrect

  * The easiest way is to use these three keys at the same time
  * is to first press the DATA TRANSFER key and then, while still pressing
  * DATA TRANSFER, press the WRITE key and while still pressing these two
  * keys, press the BULK DUMP key or BULK LOAD key.
