Hearing the song before you buy it is like trying out an effect. To see how it goes and if you like it. Like I said before. If im planning to continue PERforming it, than I will buy it. But if it doesn`t go well than I won`t and won`t continue to PERform it. Oh i'm terribly sorry you couldn't understand me. I'll try to spell it properly next time so you can figure it out. Also, try being creative and creating. If I see something, I'll work my own method whether its right or wrong and make the effect fit me. Not pay 30 bucks to learn the same thing the other 5000 12 year olds on youtube are doing.
