Thanks monsieur Patrick, i'm going to try that. I'll keep you informed about any progress.
The joystick outputs midi values from 0-127 on both x and y-axis.
I already got some results from using "scale" so no worries about bringing the values into the right range.
I'm just a bit troubled by the jumps it makes when reaching 127. The joystick starts counting down again from 127 to 0, so if i go full circle, it makes crazy jumps. Anyway, i'll try "cartopol" and see what happens.
