piku Posted March 6, 2011 Posted March 6, 2011 how can i modify the firmware of my midibox64 and midibox64e to send midi over channel 4 but receive midi (and so control the leds) on another channel?

piku Posted March 7, 2011 Author Posted March 7, 2011 (edited) i'm trying to understand but with no success... could you explain exactly where do i decide the out channel? where can i find a table with the values for each channel? what i need now is the value to send all out to midi ch3...

TK. Posted March 7, 2011 Posted March 7, 2011 Just believe me that this was the most pragmatic solution ;) Best Regards, Thorsten.
