 ====== MIDIbox Matrix - MIDI Matrix with 56 Inputs and 56 Outputs ======
 This MIDIbox implements a 56-port MIDI matrix/router using a core board and an FPGA-based add-on board together with a set of break-out boards and modules that allow for physically placing your MIDI ports where you actually need them.

 ===== User Interface =====
-The user interface (UI) is based on the [[http://ucapps.de/midibox_ng_manual_scs.html|MIDIbox SCS]], two dedicated clickable encoders for in- and out-port selection, and an additional PANIC button. It fits in the frontpanel of a standard 2U rack case, offers a 2x24 display for feedback, and 5 buttons along with an encoder for navigating the menu system. So far, an alpha prototype version of the board has been tested successfully on veroboard.

 A second generation PCB as pictured above has been ordered and tested to work. This PCB can also be used with other projects involving an SCS, e.g. the [[http://ucapps.de/midibox_ng.html|MIDIbox NG]]. Both, my favourite switches from [[16x4blm_pcb|Marquardt (6425 series)]], as well as the [[16x4blm_pcb|E-Switch TL1100 series]] (see e.g. MB SEQv4) can be used.
+==== Schematic ====
+The v1.0 schematic of the MIDIbox Matrix UI/SCS board can be downloaded {{:home:users:ilmenator:midibox_matrix_ui_scs_v1.0_schematics.pdf|here}}.
+==== Layout ====
+As with any user interface board, form follows function here. Switches and encoders are mounted on the front, everything else sits on the back of the PCB. There are mounting holes and a cutout for a 2x24 character display right above the four "soft" buttons. For the MIDIbox Matrix, SW7 (on the far right) is not used, but your project might need it.

+The total size of the PCB is 150mm x 80mm.

+* Button caps for the Marquardt's usually have to be ordered separately - these should be the 16x16mm types, not the 19x19mm!
+Note that you will obviously only need one type of switch! Not listed here are the encoder knobs, but any push-on knob for D-type shaft should work.
