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.

On Re-design

First Version:

• Drilling + Engraving + SmashTV Core32 Layout

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.

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

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)

• Velocity Offset (-+64 > with Center Postiton = normal) - 10K lin
• Random Kill (0=full Kill, 127 no Kill, Normal Position > 127) - 10K lin
• Velocity 2 TriggerLength (-+64 > with Center Position = normal 10ms, turn right:time inc by velocity in%, turn left:decrease%) - 10K lin
• Velocity Kill depending Note Kill (-+64 > with Center Position = normal > Full Spectrum) - 10K lin
• Global Accent: (0-127-normal 127) - 10K lin

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

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.

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
