Analogue-sequencer

As I played with P3 for a few days now I think it's a wonderfull but also extremely complex 
machine and therefore even though I printed Paul's manual and the standard P3 manual 
have a few questions.

It would be nice if someone would chime in and help me on my way. As I also have a new 
synth I want the P3 to play only one note for say 4 times a 4/4 meassure and in those 4 
meassures use the aux D to get the modwheel going from 0 to 127 and back to 1,

I think it's  an easy one for you P3 Pros but as everything is so overwhelming and new I 
cann't get it done after 2 days trying or don't know where to look for the info.

Thanks for helping in advance,

Martin
