====== MIDIbox DigiRoland Project ======


===== Introduction =====

The Midibox EuRoland project aims to be a **4U Re-Edit of Analog Drum Parts of Roland TR Drumachines** designed to fit in the Eurorack size Format, to be driven trought MIDI or CV.

It's the Merging of these projects:

  * [[mb-606re|MB-606RE]]
  * [[mb-808re|MB-808RE]]

===== General Design =====

2 Cases of use :\\

  * **1. Midi-Interface:** Use the MB-Modulbox Standartmodules, for Digital UI and CV+Trig-Generation\\
  * **2. Analog Interface:** Just Plug CV or Trig Jacks into the Analog Modules...without Midibox.\\

===== Configuration =====

==== MIDI Use ====

=== Main PCB UI ===

**Access** to System-Settings, Channel, NoteNumbers\\
**CV+Trig Out-Jacks** for Euroland Drum Modules \\

=== 8xPotentiometer Module ===

When using the Euroland Modules via Midi, then there are some Performance Parameters aviable:\\
All Functions have effect on all 8 Voices @ once.\\
  * **1.Velocity Offset** (-+64 > with Center Postiton = normal)\\
  * **2.Velocity Kill depending Note Kill** (-+64 > with Center Position = normal > Full Spectrum)\\
  * **3.Random Kill** (0=full Kill, 127 no Kill, Normal Position > 127)\\
  * **4.Velocity 2 TriggerLength** (-+64 > with Center Position = normal 10ms, turn right:time inc by velocity in%, turn left:decrease%)\\
  * **5.Accent:** (0-127-normal 127)\\
  * **6.------:** could be something like Roll\\
  * **7.------:** not used, could be something like a Accent for a Group of CVs\\
  * **8.------:** not used, could be something like a Accent for a Group of CVs\\

accessible via MB-Modulbox 8xPot - PCB. Just plug it in, and acitivate the AIN-Port in MIOS\\

=== MB-Modulbox 8x8 LED-Button-Matrix ===

Set CV + Trig Routing (some kind of trigger matrix), standard is 1:1 routing, so no need for this if you use a fixed setup.

==== Analog Use ====

Here are only the Analog-Drum-PCB discussed, since all other Digital UI is based on MB-Modulbox Standart Modules, the MB-Modulbox Main PCB2 is special Variant, described here.
