Clicks and crazy behavious using upsampling and parallel in Poly~
Hi,
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.
Thanks,
Alexandre
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...
I precise that this is not happening with max 5 but only max 6. I'm on max 6.1.6, os 10.8.5, MBPro i7 2011.
(and i believe that there is no parallel processing happening while switching with the attrui object or with the toggle in the inspector)
EDIT: oh yes this is because we have to turn off and on DSP again... So now we have the same clicks/weird noise using attrui/inspector.
Sorry to hear your having trouble. Can't test the patch at the moment to say if it does the same on my machine but I do believe that if you turn parallel on/off you have to restart DSP for it to take effect.
I lost 2 DAYS of work of 2 people (me and a developper i pay) because of this strange behaviour. (Trying to figure out what was wrong in our complex patch before we finally put @parallel 0) It's not just a restarting-DSP thing.
I'm not getting clicks but the @parallel 1 version definitely has a buzz that's not the sine going into it.

It appears to me that the issue is with the resampling filters. The distortions are not there for me if I turn it off.
yep, that's the resampling filters that seem to mess-up with parallel...
I'm still having the same issue here on Max 8.0.8
