How to reduce abnormal CPU usage.
I've been using Live for years, and I know (or think I know) all the tricks for reducing CPU usage. But I've run into a problem recently that I can't figure out.
When idle, Live routinely displays 20% in the CPU meter after loading a song (and buffering), and then bumps up to 70-80% while playing 5 or so audio clips. When I create a new set, the CPU meter is low, but holding down a chord on Operator creates a CPU spike to 20-30%.
I erased my hard drive and reinstalled OS X (El Capitan) a few weeks ago, so any OS indexing should be finished by now.
No other programs are running, and WiFi and Bluetooth is disabled. kernel_task is running at normal CPU levels. My buffer is maxed out. I have an Intel i7 chip and 16GB of RAM, and a 1TB SSD that's only 20% full. Pretty baffled at this point! Any ideas would be much appreciated.
