The MIDIBox JuCtrl is a Roland Alpha Juno Controller https://en.wikipedia.org/wiki/Roland_Alpha_Juno. It's an additional control surface and MIDI Controller for the Roland Alpha Juno Synth. 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.

• 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)
