In versions below 0.97.1 the panel crashes when user changes any TONE MODIFY button is pressed on the Juno itself. 

3/19/2021
In versions 0.45 and below, reloading of values from saved single files and dumps; DCO_ENV_MODE in bulk dumps was incorrect. It seems one of the dummy bytes in the 32 byte message is sometimes/always set to 01. I mistakenly presumed it would be set to 00.Please download the latest version version 0.97.1, which addresses these 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).
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 Download Juno Alpha Editor
Running as VST under Cubase
  1. In Cubase, Disable †Midi-in **Midi-out ports to the “Juno Synth”.
  2. Open Juno Alpha VST in an instrument track IN=(All Midi Inputs)
  3. Create Midi track IN=(All Midi Inputs) OUT=(“Juno Synth” Midi-in) (I record midi notes & data to this track).
  4. 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)).
  5. 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)
  6. Engage Monitor on Both tracks.
Running as VST under Reaper
This is the “Juno Synth’s” audio output)
  1. Insert – Track
  2. Record Arm
  3. Monitor Input (right-click record button)
  4. Track Input:Stereo Input
(Ctrlr VST settings)
  1. Insert – Virtual Instrument on New Track – Panel

FEATURES

  • Download BULK DUMP from Juno to panel.
  • Upload BULK DUMP to Juno.
  • Save BULK DUMP to disk from panel.
  • Load BULK DUMP sysex files from Disk to panel.
  • Load/save single patch files and send to Juno
  • cc ⇒ SYSEX mapping (Use MIDI controller to change values on panel/JUNO)‡
  • VST indexing for automation of most JUNO parameters including MODULATION and PITCH BENDER
  • Visual representation of EG Envelope.
  • Change basic panel button colours, background etc.

CC ⇒ SYSEX Mapping ‡

  1. Ctrlr – Connect your MIDI->Input/Output to the same in/out as on the JUNO.
  2. Ctrlr – Connect MIDI->Controller MIDI to your MIDI Controller keyboard.
  3. On your MIDI Controller keyboard assign a slider/knob to a cc # 0-127
  4. In the Admin area of the panel, switch on cc mapping
  5. 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.
Running as VST under Cubase
  1. In Cubase, Disable †Midi-in **Midi-out ports to the Synthesizer (Juno Alpha).
  2. Open the Juno Alpha VST in an instrument track IN=(All Midi Inputs)
  3. Create Midi track IN=(All Midi Inputs) OUT=(Synthesizer Midi-in) (I record midi notes & data to this track).
  4. In the VST Ctrlr panel connect to the †Midi-in and **Midi-out ~ connected to Synth (you disabled them in Cubase ( See step #1)).
  5. 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)
  6. Engage Monitor on Both tracks.
Running as VST under Reaper

(This is the Juno’s audio output)

  1. just can’t figure out to contact dnaldoog directly, just saying that in 0.44 both ENV MODE values are swapped, the top one should send value 00 and the bottom one 03. thanks again!

    • Hi cowudders!

      I checked in here, which haven’t been doing recently!

      You are completely right and thank you for spotting this.

      I am uploading version 0.45 immediately.

      Please check and let me know if there are any problems.

      Also any files you have saved using version 0.44 will now have inverted values for all three ENV MODE switches!

  2. Hi,

    I cant open the panel from the standalone or plugin.
    But when i double click on it.. it opens in the standalone.
    After opening it i the standalone it still doesnt work in the plugin and still cant open it in the standalone.
    Only by double clicking.

    14:15:19:000773 unknown file type says the error

    Im on mac 10.14.6

  3. Dear dnaldoog! First, let me thank you for your wonderful panel! I love it, it makes it so easy to program my alpha juno. The only trouble I have is that the juno gets overloaded if I automate the parameters in the DAW. I believe it happens because the the DAW transmits data too frequently and the buffers get overloaded with midi data, old hardware can’t keep up in speed.

    I guess already you know this site: http://llamamusic.com/mks50/mks-50_info.html#midi

    It writes:
    The MIDI Send and Receive settings on your computer might be too fast for the MKS-50/Alpha Juno MIDI buffer to handle. The MKS-50/Alpha Juno synths was designed back in Medieval times when the processor speed of a home computer was only 20MHz… much slower than the models of today at 4GHz. Try setting the MIDI transmit speed in your computer’s SysEx program to a smaller value. Recommended values for Snoize, Bome and MIDI‑OX are 390ms

    Would it be possible to implement a way to limit the transfer speeds?

    • Hi there afktr,

      I have uploaded a new version 0.97.1 which now has an option for delaying each MIDI message. 390ms seems very very slow at least for Ctrlr, so you might want to try something like 20ms or whatever. Let me know how you go.

  4. Hmm, I’m also getting “unknown file type” when I try to open the panel from within Ctrlr in Logic. I’ve been using another panel just fine but this one doesn’t seem to load. This is on OS X Catalina/Logic Pro 10.23.

    Any suggestions?

    • OK nm. Still new to this so I had downloaded the full enchilada, but turns out I just needed the .bpanelz file. Loaded up just fine.

      What’s all the other stuff for?
