====== MB-606RE ======

===== Introduction =====

The MB-606RE is a re-edit of CYM/HH and BD/SD drum parts of the Roland TR-606 to be controlled via MIDI (midibox) or CV through analog-Sequencers , in a a Eurorack-designed panel.\\
Well known Circuit Mods from around Web & time are included by default.\\

**First Version**:

  *  {{::neonking:mb606re-drill-engraving-dxf.zip|Drilling + Engraving + SmashTV Core32 Layout}}

===== General Design =====
The MB-606re is part of the EuroLand Group... (606, 808, 909)\\
It can be used in 2 Cases:\\
Midi /CV+Trig\\
**1. Midi:** Use the MB-Modulbox Standartmodules, for Digital UI and CV+Trig-Generation\\
**2. CV+Trig:** Just Plug CV or Trig Jacks into the Analog Modules...without Midibox.\\

==== Use with Midi ====
=== MB-Modulbox Main PCB UI ===
**Access** to System-Settings, Channel, NoteNumbers\\
**CV+Trig Out-Jacks** for Euroland Drum Modules \\

=== MB-Modulbox 8xPotentiometer Module ===
When using the Euroland Modules via Midi, then there are some Performance Parameters aviable:\\
accessable via MB-Modulbox 8xPot - PCB. Have to be activated via Software. (Menue Point)\\
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

=== 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 fixed setup.


==== Use with Midi or with Analog CV+Trig ====
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.

=== 606 BD+SD, 606 HH+CY ===

To spare Space: **we sandwich in 2 layers**\\ 
  * **1st PCB** : BD+SD UI-PCB / HH+CY UI-PCB  >>> Breakoutboard+Potentiometer Boards
  * **2nd PCB** : Analog Circuits: 2n We get the Analog Circuits mounted 90° angled with vertical female socket and angled DIL Pinheaders for better heat dissipation
