No need to insult us OP.
If you liked the demo enough to buy Stage, what are you doing differently?
Agree with EvilDragon - details are needed to offer help - otherwise it's just guessing.
I'd like to hear an exported audio file or at least a room recording to show us what's going on.
Also a list of gear, what's plugged into what etc. can all help.
Nobody can help without more info and maybe don't say thanks for nothing to those who are trying to help, or for that matter, those who are making this amazing software - it's just wrong - you'll understand as you grow and learn.
