I'm building a virtual mixer in PD and need to be able to switch between sets of 8 channels. I have a Motormix midi controller and it's connected to pd via Mbox2 (MIDI cables going between Motormix and Mbox2, USB going from Mbox2 to Macbook Pro). Using the ctlin object and 3 number boxes, I can see that pd is able to detect the button presses or fader movements, but I am not able to make head or tail of the values that are showing up. Whether I move a fader up or down seems to just jolt the left most output and once the motion is stopped it comes back to the same value. I guess that only detects the motion of the fader. When I connect it to a Vslider object, the slider moves sometimes and sometimes it doesn't. The middle outlet seems to have the number 47 on and when you move a slider, it shows the value for that particular slider, but comes back to 47 when you stop. When I press any button, nothing lights up on the console (though these are all supposed to light up and I've seen them lit) and now the left most channel shows the value for that button while the 47 just remains.
