+by sending sysex message you can lit or not some pads ,
+here is an exemple :
+<code>
+amidi -phw:0,0,0 -S 'F0 47 7F 40 65 00 04 43 06 00 00 F7'
+</code>
+Below are the hex Values on the force :
+{{http://dnttalo.cluster029.hosting.ovh.net/Pictures/AKFLightMapping.png}}
+In the bytes of the color , it seems that MSB are for brightness, and LSB for the color.
+As an exemple
+<code>
+low intensity on pad
+amidi -phw:0,0,0 -S 'F0 47 7F 40 65 00 04 33 01 01 01 F7'
+mid intensity on pad
+amidi -phw:0,0,0 -S 'F0 47 7F 40 65 00 04 33 11 11 11 F7'
+higher intensity on pad
+amidi -phw:0,0,0 -S 'F0 47 7F 40 65 00 04 33 21 21 21 F7'
+</code>
+In addition, i'm currently trying to understand sysex message for the small OLED screens.
+As an exemple this sysex message will draw something on the second OLED screen on the force :
+<code>
+amidi -phw:0,0,0 -S 'F0 47 7F 40 0B 00 73 01 00 01 27 56 00 20 10 08 00 00 01 00 00 00 00 08 00 02 01 00 40 20 00 00 04 02 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 00 40 20 00 00 00 02 01 00 40 00 00 00 04 00 00 00 00 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 7C 50 24 11 07 60 01 79 20 48 22 0F 40 04 13 79 00 F7'
