Dear Thorsten I have a keyboard matrix 5 octaves, velocity. I would like to connect it with core module, but I don`t know how. In the project "DIN Velocity UnMuxed" you said I have a hand draw scheme, but I do something wrong and you cannot see it. :-X (when I put the shortcut /home/qb/Desktop/1.jpg between insert image points the result is bad ; Linux FC4) So how to use keyboard matrix with core module? There are 2 connectors : IN 12 wires and OUT 11 wires. Each key from bottom has 2 switches (sensor with gum), and 2 diodes (1N4 148 or IN4 I48) C1 : signal from 1 wire IN go to 1diode , next to 1 switch and next to 1 OUT wire C1 : signal from 2 wire IN go to 2diode , next to 2 switch and next to 1 OUT wire C1# : signal from 3 wire IN go to 3diode , next to 1 switch and next to 1 OUT wire C1# : signal from 4 wire IN go to 4diode , next to 2 switch and next to 1 OUT wire D1 : signal from 5 wire IN go to 5diode , next to 1 switch and next to 1 OUT wire D1 : signal from 6 wire IN go to 6diode , next to 2 switch and next to 1 OUT wire D1# : signal from 7 wire IN go to 7diode , next to 1 switch and next to 1 OUT wire D1# : signal from 8 wire IN go to 8diode , next to 2 switch and next to 1 OUT wire E1 : signal from 9 wire IN go to 9iode , next to 1 switch and next to 1 OUT wire E1 : signal from 10 wire IN go to 10diode , next to 2 switch and next to 1 OUT wire F1 : signal from 11 wire IN go to 11diode , next to 1 switch and next to 1 OUT wire F1 : signal from 12 wire IN go to 12diode , next to 2 switch and next to 1 OUT wire F1# : signal from 1 wire IN go to 13diode , next to 1 switch and next to 2 OUT wire F1# : signal from 2 wire IN go to 14diode , next to 2 switch and next to 2 OUT wire G1 : signal from 3 wire IN go to 15diode , next to 1 switch and next to 2 OUT wire G1 : signal from 4 wire IN go to 16diode , next to 2 switch and next to 2 OUT wire G1# : signal from 5 wire IN go to 17diode , next to 1 switch and next to 2 OUT wire G1# : signal from 6 wire IN go to 18diode , next to 2 switch and next to 2 OUT wire A1 : signal from 7 wire IN go to 19diode , next to 1 switch and next to 2 OUT wire A1 : signal from 8 wire IN go to 20diode , next to 2 switch and next to 2 OUT wire B1 : signal from 9 wire IN go to 21diode , next to 1 switch and next to 2 OUT wire B1 : signal from 10 wire IN go to 22diode , next to 2 switch and next to 2 OUT wire H1 : signal from 11 wire IN go to 23diode , next to 1 switch and next to 2 OUT wire H1 : signal from 12 wire IN go to 24diode , next to 2 switch and next to 2 OUT wire C2 : signal from 1 wire IN go to 25diode , next to 1 switch and next to 3 OUT wire C2 : signal from 2 wire IN go to 26diode , next to 2 switch and next to 3 OUT wire C2# : signal from 3 wire IN go to 27diode , next to 1 switch and next to 3 OUT wire C2# : signal from 4 wire IN go to 28diode , next to 2 switch and next to 3 OUT wire D2 : signal from 5 wire IN go to 29diode , next to 1 switch and next to 3 OUT wire D2 : signal from 6 wire IN go to 30diode , next to 2 switch and next to 3 OUT wire D2# : signal from 7 wire IN go to 31diode , next to 1 switch and next to 3 OUT wire D2# : signal from 8 wire IN go to 32diode , next to 2 switch and next to 3 OUT wire E2 : signal from 9 wire IN go to 33diode , next to 1 switch and next to 3 OUT wire E2 : signal from 10 wire IN go to 34diode , next to 2 switch and next to 3 OUT wire F2 : signal from 11 wire IN go to 35diode , next to 1 switch and next to 3 OUT wire F2 : signal from 12 wire IN go to 36diode , next to 2 switch and next to 3 OUT wire . . . . . . . . . . . . .. . . . . . . . . . .. F5# : signal from 1 wire IN go to 109diode , next to 1 switch and next to 10 OUT wire F5# : signal from 2 wire IN go to 110diode , next to 2 switch and next to 10 OUT wire G5 : signal from 3 wire IN go to 111diode , next to 1 switch and next to 10 OUT wire G5 : signal from 4 wire IN go to 112diode , next to 2 switch and next to 10 OUT wire G5# : signal from 5 wire IN go to 113diode , next to 1 switch and next to 10 OUT wire G5# : signal from 6 wire IN go to 114diode , next to 2 switch and next to 10 OUT wire A5 : signal from 7 wire IN go to 115diode , next to 1 switch and next to 10 OUT wire A5 : signal from 8 wire IN go to 116diode , next to 2 switch and next to 10 OUT wire B5 : signal from 9 wire IN go to 117diode , next to 1 switch and next to 10 OUT wire B5 : signal from 10 wire IN go to 118diode , next to 2 switch and next to 10 OUT wire H5 : signal from 11 wire IN go to 119diode , next to 1 switch and next to 10 OUT wire H5 : signal from 12 wire IN go to 120diode , next to 2 switch and next to 10 OUT wire C6 : signal from 1 wire IN go to 121diode , next to 1 switch and next to 3 OUT wire C6 : signal from 2 wire IN go to 122diode , next to 2 switch and next to 3 OUT wire In worse case I`ll sctch a board and separate each switch IN (from only 12 to 122 :-\), connect all OUT "groundes" togetcher and use 4 DIN4 modules. But is this to possible to use orginal matrix, for free DIN for additional switches, encoders? How about latency ? Thank you T.K.
