João,,
The other message that does gop is coords. I do not know the complete message but this works
[toggle] | [coords 600 600 700 700 1 1 $1( | [s pd-pd-arrayz]
[pd pd-arrayz]
clicking toggle displays or hides [pd pd-arrayz]
your canvas and hradio on dsp is genious. I could not find bezier or swatch. I will have to update my pd. I did see the sliders it is pretty cool. thanks
