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:

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.
