The Logic Off Topic list

I am using Virtual Guitarist on Logic Pro.

One of the parameters of this virtual instrument is called "part" - 
there are up to eight variations on the riff, you can move between them 
in real time by clicking on the buttons on the instrument interface.

When I zoom into the track automation for this "part" parameter, the 
zoom level isn't high enough to isolate the 0-8 range I need from the 
0-127 total, so it's a fiddly business drawing in the points.

I think it would be easier to control this parameter in real time 
through my digital piano - using the lowest eight notes which I don't 
really play.

I believe I need to create a transformer in the environment that would 
transform these note events to controller events - or are they "meta" 
events? I don't know how the transformer works - could anyone explain 
how to create this?

Thanks
