====== 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]]) ====== Details ====== * Ju Control CS (LED's, Buttons, Encoders, LCD) | => {{:juctrl:juctrl_cs_mbhp_btn_led_enc_lcd_pin_numbers_and_symbols.pdf|}} (08/2012) * 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 {{:juctrl:juctrluserpanel.jpg|}} ====== Project Status ====== 09/2012 || || --- Project Start [28 October 2011]: || --- 100% JuCtrl MBHP DIN, DOUT, LCD, ENC || --- 100% MBHP IIC MIDI Module (one extra MIDI IO for Juno) || --- 100% CC MIDI IN --->[Ju Control (MIDI CC to SYSEX Conversation)] --->MIDI OUT--->[Juno] || --- 100% Program Change (Sound Patch) via CS ENC || --- 100% Send Individual CS Controller Values to Juno (Juno IPR-Mode SYSEX, CC) || --- 100% Receive Individual Tone Parameters from Juno (Juno IPR-Mode SYSEX) || --- 100% Send All CS Tone Parameters to Juno (Juno APR-Mode Sysex) || --- 100% Receive All Tone Parameters from Juno(Juno APR-Mode Sysex) || --- 100% HW: Update Core8 >> PIC18F4620 (Need more Program Memory and SRAM for BLD-Mode Sysex Data) || --- 100% Bankstick (BS 1-8 = 8*128 Tone Patches) || --- 100% ENVELOPE functions (BTN F1-F4) || --- 100% Send Bankstick sysex-dump (Tone Backup) || \/ ====== Software ====== * [[http://www.subf.net/midibox/JuCtrl/JuCtrlV100018F4620.zip]] (09/2012) ====== Links ====== - [[http://midibox.org/forums/topic/16197-ju-control/]] - [[http://en.wikipedia.org/wiki/Roland_Alpha_Juno]] - [[http://www.vintagesynth.com/roland/ajuno1.php]]
