MIDIbox Quad Genesis: Front Panel
To build the front panel of MIDIbox Quad Genesis, you will need (details on each part below):
An aluminum front panel
A PCB to hold all the buttons, LEDs, encoders, etc., and of course all these electronic
components themselves
A bunch of 3D printed transparent button caps
Some 3D printed transparent LED pipes for the FM widget
A 2×40 standard MIDIbox-compliant character LCD screen
Knob caps for the encoders, including a datawheel-style cap for the datawheel encoder
The dual-gang and single-gang potentiometers (one each per synth, not per module!) for the
Genesis module volume controls, and their appropriate knob caps (see MBHP_GENESIS)
A whole bunch of M3 or 4-40 screws, nuts, washers, and standoffs
Standard MIDIbox 10-pin and 16-pin IDC cables, for connecting the front panel PCB to the core's
J8/9 and for connecting the LCD to the core's J15A
Dimensions
The aluminum (or acrylic) front panel of MIDIbox Quad Genesis is 15“ x 11” (38.1 x 27.9 cm), and the
front panel PCB itself is 13.85“ x 9.85” (35.18 x 25.02 cm), leaving a 0.57“ (1.45 cm) border around
the edge. The aluminum I used was 1/16” (0.062“ or 1.57 mm); this may be a consideration if you use
acrylic which is much thicker (2mm should probably be fine but 3mm might be a problem, with the 3D
printed buttons).

The spacing between the underside of the front panel and the upper side of the PCB is about 0.27” (7
mm), which is originally defined by the encoders and the 3D printed buttons are made to match this. I
used 1/4“ nylon spacers/standoffs from eBay plus a flat washer (4-40 or M3) to achieve this spacing. I
used 0.75” 4-40 screws to put together the front panel, in which case the depth of the assembly was
0.75“ with the electrolytic capacitors and pin header / IDC connector sticking out past this. The panel
and PCB can be fastened together with 4-40 or M3 screws.
Aluminum Front Panel
There are two designs available here: my original, and a modified design with the LED pipes in the
LED rings having been replaced by 3mm LEDs just sticking through holes in the aluminum.
It took me over 2 hours just to insert the tiny LED pipes in the slits in one single front panel with the
first design, which is why I recommend the second. Since they're 3D printed (see below), they have a
small range of sizes, and at that scale some are too big and some are too small. I still left them in
place for the FM widget and the DAC VU meter; if you don't want those either for some reason, it
shouldn't be hard to replace them with holes.
All the LED holes and screw mounting holes are 1/8” (3.17 mm), which should give 3mm LEDs a little
play (some are in practice slightly wider than 3mm, and some aren't actually 3mm at all), and are
also big enough for both M3 and 4-40“ screws. On my own panel, I had to drill out some of the holes a
bit for the yellow and green LEDs sticking through the front panel; I recommend you buy the LEDs
you're going to put through the holes first and measure them before you have the front panel
manufactured.
It may be possible to make the front panel out of acrylic, a-la MIDIbox SEQ V4. Since the front panel
PCB is bolted to it in many places, it will probably be sturdy enough. If it's not, there's a row of screw
holes slightly below halfway down the panel, and maybe you can have those screws go into an
aluminum bar spanning the width of the front panel and attaching to the sides of your case, to
provide extra support in the middle.

Parts List for MBQG_FP PCB
This is the set of parts I used to build the two MIDIbox Quad Genesis units I constructed. It can also
serve as guidelines for if you're building your own board from scratch on veroboard. Here are some
notes and caveats:
As explained above in the section of the aluminum front panel, I used LED pipes for the LED
rings, to give them a distinctive oblong shape. To save money on the milling costs and labor on
inserting hundreds of tiny plastic pieces into the front panel, most of which are either too small
or too big, I recommend making the LED rings just by having 3mm LEDs sticking up through the
aluminum. In this case, the LEDs I used below will be too bright to look at directly–they were
used to illuminate the LED pipes. So please consider changing to different LEDs.
Please note that for the LEDs which are under illuminated buttons or under the remaining LED
pipes, you will need LEDs which are very bright like the ones below! Cheap 1mcd LEDs will be
completely invisible! You need at least 1000mcd; the brightnesses I used are listed below. If you
are going to the trouble of making this thing, don't skimp on the LEDs!
Also don't skimp on the encoders! For MIDIbox FM V2.0/V2.1 I used cheap encoders from China
to save money, and many of them barely work anymore!
Of course, the color of all the LEDs is completely up to personal preference, though you should
always use the same two colors beneath all bi-color buttons. Please plan out carefully how
many of each type of LED you will need based on your color preferences and which LEDs will be
sticking through the front panel versus lighting up buttons or light pipes. Trust me, you don't
want to use regular LEDs to try to light up the plastic, it'll look dim and poor; and you don't want
to use the high-brightness LEDs sticking through the front panel, they will blind you!
On the PCB itself, the individual buttons, LEDs, and diodes are usually not marked. To simplify
PCB design in KiCad, “assemblies” were created with e.g. an encoder and 16 LEDs, or a button,
two LEDs, and a diode. This is why they're marked “A21” or whatever. All the diodes are the
same 1N914 or 1N4148 (or actually any through-hole small signal diode), and each one has a
cathode marking, so there should never be any confusion. With the exception of the LEDs in the
LED rings, every LED on the board has an actual diode symbol marked, so there should be no
confusion about which direction they go (square pad is anode is longer lead). In the LED rings,
the four quadrant LEDs' directions are marked, and the rest go in the corresponding direction,
following around the circle (anode always on inside). All the tact switches are also the same–just
make sure each one is pushed in fully before soldering!

Yellow LEDs for panel indication (Tinted, Diffused) (For
some reason I ended up using these only for the
yellow LEDs in the commands display and the load
meter, not for the crosspoints in the FM widget; it may
have been because I wanted clear-looking LEDs in the
FM widget to go with all the other clear/white things
there, or because these LEDs are closer to yellow than
to amber, and the other LEDs in the FM widget were
more amber)

light up blue; and actually these are a bit too bright to
use for sticking through the front panel. You could
fudge something with the resistors supplying these

recommend looking for alternative LEDs.)

Schematic and Reference Designators
Schematic image (unfortunately, MIDIbox Gallery scaled down the original image, and offsite
documentation is frowned upon):
For Color fields, as discussed above, you may change the colors to whatever you want, but it is
recommended to keep the colors consistent (e.g. make everything “green” below be the same color,
and everything “red” below be a different color). For the Red/Green buttons below, the Red LED is
always on the left and the Green LED is always on the right.

Custom PCB / Veroboard Info
This is the mapping for the MBQG_FP board itself–if you have the commercially produced PCB from
Sauraen, you don't need this info because it's already in the copper!
MIDIbox Quad Genesis supports its front panel controls in any valid MIDIbox button-LED matrix
configuration, with the following restrictions:
DOUT Restrictions
The same BLM must be used for buttons and LEDs, and it must have 8 rows.
LED display digits must be common anode, connected with their anode to a DOUT shift register
pin, and their cathodes to the row lines in the order 0-7 = A-B-C-D-E-F-G-DP.
DIN Restrictions
The same BLM must be used for buttons and LEDs, and it must have 8 rows.
Encoders must have their common pin grounded, and their two switching pins directly

2020/11/14 19:23 9/15 MIDIbox Quad Genesis: Front Panel
MIDIbox - http://www.midibox.org/dokuwiki/
connected to two DIN shift register pins (not in the matrix).
For now, the mapping is hard-coded in frontpanel.c, but eventually (if there is interest), it will be read
from a text-based configuration file on the SD card upon startup. If you match the matrix maps below,
you won't need to edit this at all.
DOUT Matrix Map
Syntax:
X = no item
B = button
EB = encoder button (push)
L = LED
R = Red
G = Green
G# = Genesis #
O# = LED Ring Segment # (counted from bottom, clockwise)
LW# = LED, FM Widget, Reference Designator # (since there is no good way to label the
individual widget segments)
All LED display digits are wired, from rows 0 to 7: A-B-C-D-E-F-G-DP
VGM Commands Matrix is wired, from top to bottom, 0-1-2-3-4-5-6 (row 7 not used for any columns)
Counting the individual segments in the LED displays, there are 638 LEDs on the front panel.
