Hi, I'm quite new of pd.
I did a project where I render squares of different colors from midi notes. I mean: when I play a DO it renders a blue square, when I play a RE it renders a red square and so on.
Now my question is: if I would like to render different geos from different notes? For example, if I play a DO it renders a square but if I play a RE it renders a circle. Is this possible with gem?? Does gem have the power of doing it?

Excuse-me for my english, but I'm italian
