I want to create a patch with a canvas in graph on parent. But when I use that patch in another patch more than once, all of the canvas's change together, because I had to send the information to the canvas, and they all have the same receive name.

Is there a way to address a canvas using a cable, so that when I use more than one, they change independently? I hope I am being clear, this is tough to describe.

Use $0 to give the [cnv]s unique names. Pd replaces $0 with a unique number for each patch and abstraction, so you can keep [send] and [receive] local to each instance of the same patch. So, for your [cnv], change the receive name from, say, "receivename" to "$0-receivename", and you'll be able to make as many instances as you want without them cross communicating with each other. Take a look at "2.control.examples/13.locality.pd" to see an example.

Edit: Where can I find that example patch?

Maelstorm strikes again. Thanks

I am still having trouble even after looking at that example. I want to make a custom toggle that changes colors when it's on or off. When I make more than one of these toggles, they all change color together. When I try to put $0-receive into the canvas receive and a [$0-receive color 15( message in the patch, I get the error "0-receive no such object." What am I doing wrong?

There can be no $0 in a message box - message boxes replace $ symbol with something they receive into their inlets ($1, $2, ...). Use a message box (color 15) connected to a [send $0-receive] object that can do the appropriate $0 replacement.

Got it! Finally. Thanks ktsouk.
