Is there any way of receiving this kind of information? I could really use it in my patch. At the very least, a "bang" when I turn on/off the DSP.

Thank you for your time,

[route dsp]

[x] <- this is a toggle

..Shure. Pd talks to you through a [r pd]... Or maybe have a look at [switch~].

damn...

Thanks so much guys. alexandros's solution works great

Hi there, is there also an easy way to tell if when a subpatch is switch~ed on or off (from a parent patch)?

Since you need to control [switch~] to set the DSP state of a subpatch, I think the best you can do is to just send it's state somewhere to the parent patch using [send] or [value], or something like that.
