How can a button light on and send sysex again?

Question

Hello,

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.

Regards

Answer 1

Normally I would group the four buttons under one master control, and under super control options, chose the option that second press resends on value.

But your use of the second value sent on off muddles this solution.  Is the off sent only when you change to a different button?  In this case, this would work.

But if you want alternate presses of the button to keep the control illuminated, but alternate the message sent, this may be difficult.  You might need a second set of display only buttons, to show the last control used.  Building the appropriate display logic might require a few chained controls.

A simpler work around would be eight buttons, dividing the on and off between two buttons.  The grouping under one super with second press resends on, buttons send on only, would sort it out.  Not as elegant, but save the hair required to be pulled out while sorting the chained supercontrol logic.
