Hi there

i have serious problems with my first big reaper project. everything worked fine until a not reproduceable point, then everything started running out of time (part of arrangement start earlier/later, sounds granulize, pieces of audio "hang";...)

i admit that cpu load and trackcount is high and i am using dsp-hardware (liquid mix), various vsts and a reainsert on my masterbus.

as i said, seems like a point of no return. even if i deactivate plugs and freeze tracks it wont get any better.

any ideas?
