The documentation shows F0 42 3n 03 41 xx yy F7. Translated to DMP2 speak: 42 L 03 41 xx V, where xx is the parameter number.
The channel format is shown as 3nh, or 30 to 3F. So the channel changer for this control needs to have a midi min of 48, max of 63, 16 ticks, display 1-16
I did not see a traditional channel changer for cc controls. But but if you have one, it could be combined with a supercontrol. Settings for this super control will be Midi 0 - 127, 16 ticks, display 1-16.
