I've made a pretty simple M4L-device, a ringmodulator with pitch-tracking, i.e., it tracks the pitch of the incoming signal and uses some userdefined fraction of that number as modulation frequency.
Everything works just fine when I have the Max editing window open, but as soon as I close Max and run it solely in Live, the CPU meter in Live starts soaring. In a matter of 20 seconds it goes from 20 to 250 percent... Needless to say, audio suffers badly...
I'm using the sigmund-external for pitch-tracking, and I'm guessing that's the culprit.. Anyone have any bright ideas?
Hardware: Macbook Pro 15", 2,4GHz i5, 4 GB RAM, Focusrite Saffire Pro 14 soundcard
Software: OSX 10.6.7, Ableton Live 8.2.2, Max/MSP 5.1.8
All and any help much appreciated!
