PD's Help System

In the process of learning PD (in particular, trying to understand ex. 3.16), I've been poking around the PD help system. Curiously enough, the help "pages" are actually patches in their own right. In my case, I went looking at the help page for [stripnote], (Help, Browser, 5. Reference, Stripnote), and the window that comes up lets you play with a [stripnote] object. Click on the note-on message (the message box on the right), and you get print output on the console window; click on the note-off message (on the left), and you get nothing.

The other thing that's cool about the whole visual programming paradigm is being able to connect a number box to one of the outputs of, say, [notein], and watch what's happening as you play keys on a keyboard. I believe you can also get a graph of a waveform displayed in a control every so often, but I'm still figuring out how to do that.

Pretty neat that PD lends itself to such play.
