MIDIbox

Fadercore

Standard 220mm wide modules

A solution to add up to 32 Motorfaders to your Midibox Project. It contains 2 different Types of PCBs one is the VLR-MF_NG and the other a slim PCB to mount to your Fader so its detachable for service.

Allways look for the cheapest seller, the Price may vary heavy!!! And look for Local dealers preferred. http://www.midibox.org/dokuwiki/doku.php?id=where_to_order_components

To make a small and easy to connect matrix over a hole Frontplatte is no fun. Thats why i made myself a better solution. Based on the common DOUT modules it can be connected to 3 SRs.

The PCB is available under: https://www.vlrlab.com/home/18-ledmatrix.html https://www.vlrlab.com/home/19-meterboard.html

The LEDs are mounted to the Edge of the Meterboard to get a very slim form. That makes it a bit harder to solder them but i guess that no one wont be able to do it. To solder the Header to the Edge there is a wite triangle printed to the PCB on one side. This Triange has to match with the Triangle on the Header.

Well you should now by now how to solder Headers…

Connect the SEL, Row1-8 & Row9-16 with each a DOUT Header.

I use a Encoder connected directly to a DIN to test. Assuming that the DOUT is the first device on the chain of J8/9 we need to configure it like this:

RESET_HW

LCD “%C”
LCD “@(1:1:1)OLED1”

# Test D-OUT LEDmatrix board

DOUT_MATRIX n=1 rows=8 inverted=1 sr_dout_sel1=1 sr_dout_r1=2 sr_dout_r2=3

# Matrix control by a Encoder connected to DIN

Im using my VLR-8oDisp board to show the Values of the encoder. You can change it to any other type of Display-setting… lcd_pos=6:1:5 {6=Display number : 1= X-axis : 5= Y-Axis (row)}
