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.

• 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

JuCtrl Hardware:

• 1x MBHP Core8 (PIC 18F4620) | ⇒ (http://www.ucapps.de/mbhp_core.html)
• 1x LCD Module: 2×20 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)
