don't get too caught up adding FX and polish until you have a pretty sufficient song written. It is easy to write a dope 4 bar loop and start messing with FX and whatnot, lose track of what you were doing and ultimately lose interest. The plague of this machine is how easy it is to churn out 4 bar loops and how hard it is to finish a track. Sketch the ENTIRE track first, THEN polish and you will be a lot better off. Look into song mode tutorials.
