I have a layout designed for an arranger module from Ketron, SD40. With it I control microphone, auto accompaniment and other things with the help of sysex data. so far everything works wonderfully. but with the four different buttons for variations of the accompaniment I have an optical problem and no idea how to solve it.
The four buttons send two sysex data in each case, the first on pressing the key, the others on release. everything clear so far. if I press the same button again and again, the variation remains the same, but a fill in is played. How can I get it, that the button of the currently used variation shines, but nevertheless can be pressed several times in succession and sends again and again the appropriate values?
I hope it's understandable what I mean.
