Hello,
My English is not very good. I am trying to build an electronic stop knobs board. If I press a knob I want a signal to my grandorgue program. Later on I want to connect leds to indicate the state of the button.
I made board, soldiered the button switch and connected them to a dio_matirix. The lpc17 had an old bootloader with midio128. I succeeded in installing midibox NG. The file "default.mio" was still on the SD card so I deleted it.
The stop knobs (buttons) are not working out of the box. All the column buttons send the same note.
I read a lot of manuals, but I do not get clear where to start. Probably edit the "default.ngc"....
Any help is appreciated.
Robert
