@christoph-hart This works beautiful, I even made a compliment to this using 5 leds that lights up for each button, however I than had to make the ledStates with 5 columns instead of 4, and use:
"for(i = 0; i <5; i++)
{
Lamps[i].setValue(!value == 1 - lampStates[index][i]);
}
and it works fine.
Now to another question, I have 3 different states of the keyboard as well, and I want to set them with the same buttons as the samplers (I have key switches on some keys with coloured keys, and I want to show them and also the key range for that instrument, only in one of the buttons states.
Is there some tutorial or document around that I can study for this matter?
