a few things will happen, you will find that there are so many things you may very well be a little overwhelmed.
but if you go with a lighter version or ms6 you may find you don't have the tools to do the things you want.
here's the thing with sonar x2,
it has so many features that it actually brings out more creativity in you. you have more tools to do more things, thus expand your creative process.
this is most obvious in session drummer 3 compared to studio instruments.
or z3ta compared to cakewalk sound center.
I know a lot of people who have bought sonar essentials that had wished they bought producer.
there are more advanced features,but they're hidden so its not like its more confusing.
my advise is to take your time, try the demo, enjoy it.
if you find it is everything you love,then wait for a deal to pop up.
there are always deals on sonar x2 poping up here or there, like getting freebee's with your purchase or 100.- off the retail price.
