b.t.w.: ardour looks great ...

You're right. That's the easiest way to do it and makes sense.

I only thought about doing it 'the hard way' so that my GUI is 
consistent. I have now 23 sliders with the values above and I didn't 
want to pack everything in a box with a label.

But thanks. If nothing else helps that's definetely the way to do it ...
