I get clicks and crazy behaviours using upsampling 2 and @parallel 1 in Poly~
This behaviour seems to happen only when i use @parallel 1 as argument, not while switching with the attrui object...
see patch attached.
P.s: And in a more complex patch it seems i also have crazy cpu problems without upsampling, and even also without using parallel, while sending a lot of max messages inside the poly~ while without using poly~ my abstraction works super fine. I'm kind of generally having bad luck with poly~ and my complex patches...
