I'm a newbie to Pd and I can't seem to figure out how to do what I need. I want to send a bang when pix_blob records a specific X and Y value respectively.

might be a faster way to do it, but:

[== #x] [== #y]
| /
| /
[&& ]
|
[sel 1]

where x, and y are the specific values you want.

Thank you so much for your help! I was able to figure it out!
