Greatly Varying CPU Strain?

June 30, 2008 | 9:13 pm

Hi, so I was running a patch earlier today and it used 40-60% of my CPU’s processing capabilities. Now, I run the patch and there’s these random spikes to 100%. I disconnected everything that could cause that much strain on my CPU, disconnected the resonators, filters, and all synths, so that it’s a single [play~] object being driven by a phasor, and I’m still at 30% CPU use with spikes to 70, 80 or 90%. What could be causing these spikes? I tried restarting MaxMSP and it’s still happening. Suggestions?

Maybe the mac Airport problem mentioned a few times on this forum ?

another peculiar thing: i am getting a ‘nan’ reading on my phasor signal when it is probed. what does this mean? also, even when i have no samples loaded in the patch, so there couldn’t possibly be any signal processing going on, my CPU utilization is at roughly 25% with spikes going as high 100%.

beautiful. fixed :-D thx. though i still don’t know why my phasor’s say ‘nan’ when probed? I have to retype in their arguments for them to be fixed.
