I'm woring on my song "In heaven"! (Demo)
With 16 channels (3 sytrus channels), 15 automation clips and 16 pattens this song comes up on 100% CPU all the time! It's because of one of the sytrus channels. When i only play that, the CPU reaches 50%. It's really annoying. So i'm doing my best to make it good!

P.S. Here's a screenshot! (See the CPU)
