thank you for your answers.
you could still sell the launchpad and get an APC20, btw.
If I would use Ableton I would get an APC 40 or 20 for sure.
I tried the program but I just fail to like it.
The Launchpad interests me because it has no sliders !
I just want pads that blink

I have sliders and knobs already on my Keyboard.
we'll see. I guess i will just contact Novation to enquire some more into this.
