Here you can download short video about this problem:
http://s22.quicksharing.com/d/4082947/1 ... 3/live.avi
As you can see in the video, CPU spikes when cursor jump from end to start of loop region (this is common behaviour in all Live's versions).
There are the same tracks at the begining and at the end of loop region with same audio, VST and VSTi, no difference along whole region.
CPU spikes cause sound artefacts of course.
Tested also on Cubase, FL Studio, Sonar. NO spikes, no artefacts, only pure music and comfortable work...
Any1 noticed similar behaviour in Live 6 BETA?
