@midiculous Thank you for showing me this, I have had a lot of problems with extracting meta data when importing.

@christoph-hart It's called intuition and don't try to understand it

@christoph-hart With the latests code of June 5, it's crashing no more!

@christoph-hart Ok, I think I understand a little bit, I will try to follow your suggestions. Thanks a lot!

@d-healey I'm trying to control several functions with an array of key switches , if Message.getNoteNumber() == 47) then, ignore midi events in MidiMuter1, enable RoutingMatrix1, make panel visible, etc...

I am able to get this to work using one (Message.getNoteNumber()) at the time, controlling several functions but it would spare me a lot of writing if it was possible to use all (Message.getNoteNumber()) in an array.

I guess I'm, as we in Sweden say "Helt ute och cyklar" (translated "completely outdoor biking")

Is it possible to make an array like this:

const var Keyswitches = [Message.getNoteNumber() == 47),
Message.getNoteNumber() == 48),
Message.getNoteNumber() == 50)];

and if, in what callback do I declare it?

@christoph-hart New project, make Content.makeFrontInterface(600, 500);
in Widget list - Interface , make a new button (root), make a new panel(root), in Widget list, grab button with mouse, drag it to the panel, crash.

Hise (3673) crash when dragging objects in "Widget List" on MacOS 10.12.6

@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?

@christoph-hart Yes. as I said before, what a great forum !!
Thank you Christoph! I am grateful for the code, I will study it and learn
Cheers!
