====== MIDIBox Juno Control (JuCtrl) ======

{{http://www.subfrequenz.net/visuals/albums/userpics/10001/20120316MidiboxJuCTRL002.jpg}}

====== Project Description ======
The **MIDIBox JuCtrl** is a **Alpha Juno** MIDI Controller [[https://en.wikipedia.org/wiki/Roland_Alpha_Juno]]. It's an additional **control surface** and MIDI Controller for the Roland Alpha Juno Synthesizer. I started this Project because the original Juno User CS is very minimalistic (80s Style). With the **MIDIbox JuCtrl** is every Tone Colour parameter directly at hand. Furthermore you can store all 128 Juno Tone Patches on Bankstick.


====== Functions ======
  * Control every Juno Tone Parameter with an encoder or button 
  * Control one parameter (IPR) or send all parameter at once (APR)
  * Store Juno patches (Tones) on Bankstick
  * Juno Tone parameter overview (via CS LCD & LED)
  * MIDI processing: CC to sysex conversation 


====== Hardware ======
**JuCtrl Hardware:**
  * 1x MBHP Core8 (PIC 18F4620) | => ([[http://www.ucapps.de/mbhp_core.html]])
  * 1x LCD Module: 2x20 LCD (8bit) | => ([[http://www.midibox.org/users/jim_henry/building_a_midibox_lcd_cable.pdf]])
  * 2x MBHP DOUTx4 | => ([[http://www.ucapps.de/mbhp_dout.html]])
  * 3x MBHP DINx4 | => ([[http://www.ucapps.de/mbhp_din.html]])
  * 1x MBHP IIC MIDI Module (extra MIDI IO for Juno Synth) IIC MIDI adr. = 0x10(J3 port) | =>([[http://www.ucapps.de/mbhp_iic_midi.html]])
  * 1-8x Bankstick | Store 128 Juno Tones [24256(32k)] =>([[http://www.ucapps.de/mbhp_bankstick.html]])

  * Ju Control MBHP DIN & DOUT | => {{:juctrl:juctrldindout.pdf|}} (08/2012)
  * JuCtrl Juno MIDI IO Dataflow Overview | => {{:juctrl:juctrldataflowoverview.pdf|}} (08/2012)

====== Notes ======

  * **Note:** Set **SYSEX ON** @AlphaJuno (JuCtrl will not work if SYSEX = off)

  * **Note:** JuCtrl CS will pick up all the TONE (Sound) Parameters automatically - if you make changes @Alpha Juno

  * **Note: SET JUNO SYSEX ON**
    - @Alpha Juno: Push the [MIDI] Button as many times until the MIDI SYSEX OPTION "MIDI EXCL" appears. 
    - Use the dial for changing. 
    - By writing the data of the MIDI Function setting into the back-up memory, it can be retained even when the Juno is turned off: 
      * set the Memory Protect Switch to OFF position. Push the MIDI Button.  
      * While holding the Write Button down, push the MIDI Button. The Juno Display will change to: "Write MIDI FUNC."
      * When the MIDI Button is pushed: "Write Complete!"

  * **Note: WRITE JUNO TONE DATA TO BANKSTICK**
    - SELECT THE PREFERRED BANKSTICK (1-8) with [SELECT BANKSTICK] BUTTON and [VALUE] ENCODER
    - SELECT YOUR PREFERRED BANKSTICK AREA with the [MIDI ProgChange] ENCODER
    * MIDI ProgChange =  1-64  = You will WRITE Juno Tone Colours to BANKSTICK 1 -64
    * MIDI ProgChange = 65-128 = You will WRITE Juno Tone Colours TO BANKSTICK 65 -128
    - Set [PRESET] (64x PRESET TONE COLOURS) or [MEMORY] (64x MEMORY TONE COLOURS) @Alpha Juno
    - PRESS: [DATA TRANFERE] + [WRITE] + [DUMP] @Alpha Juno
    - Now JuCtrl will RECEIVE 64 TONE COLOURS via SYSEX-DATA and write 64x TONE PATCHES to your selected BANKSTICK.
    * All Done. 
    * BROWNS THE STORED TONE COLOURS with the "SELECT BANKSTICK TONE" ENCODER (0-127)
    * THE TONE NAME WILL APPEAR ON THE JuCtrl LCD. LOAD A STORED TONE COLOUR WITH THE BUTTON "SEND TONE TO CS"
    * NOW THE CS IS LOADED. 
    * PRESS [SEND TONE TO JUNO] BUTTON for WRITING THE CURRENT CS DATA BACK TO ALPHA JUNO
