Hi there! I'm actually copying step by step this fantastic patch I found on youtube:

My question is: Whenever I try to use the objetc appearing at 4:00, id est, a "0xa-snap" object, pd won't recognize it. Should I download some package I'm not aware off? Is it simply made by the author?

By the way, this patch makes uses extensively of the expr~ package. Any idea where can I find a great tutorial about it? I'm not myself too used to C programming so I miss most of it.

Thanks in advance,

running Pd-Extended 0.42.5 on Mac OSX Lion 10.7.3

Here is the patch up to 4:00

I've copied the patch myself cause it's really a great one. This [0xa-snpa] must be a GOP abstraction (graph-on-parent), this guy must have made. Anyway, it looks like it's only something like a beat counter. He doesn't connect it's outlet to anything (it actually doesn't have any outlets). So, you can carry on, ignoring that object.

Here's a page about the [expr] family, with their features

My guess is that you don't need this object. It has no output. It looks like an abstraction made to check what's going out of the [expr~] that is just above.
