Thank you for the quick reply, you clearly answered but I still can't get completely (yeah I look slightly dumb :-). I even don't get what a “track” can be in this situation...(a channel?) By the way, let me try to summarize what I (probably) understood.

I see that each pad covers at least 2 functions: to recall a page inside a pre-selected bank, to select a step (whose pitch has to be manually set via knob) within the page. Since there are 12 pads, and the outs are just 6, I have to deduce that each of the 6 outputs deliver alternatively both 6 top and 6 bottom row pads (as well as each knob controls the pitch of both top and bottom row pads, correspondingly).
If this is right, the presence of 6 outputs still confuses me. Am I right to consider this controller intended to “play” monophonic modules? If yes, the voltage values (pitch infos) will never be put out at the same time. Thus, what are the applications for the 6 outs? Are they normalled to the 1st?
