Yeah, I`ve done my time on poverty row for my music.
I`m lucky to now have a very well paying job, in which I can work as many hours as I choose.
But I`m looking to move more full time in the studio, as I don`t just make techno, there is a lot I can do with the other music.
So if you want to go full time into the studio, do something other than techno, variety is the spice of life, and making the same type of music all the time will lead you to repeated methods etc anyway.
As for selling your soul? why, you can make very commercial music and still put your heart and soul into it without compromising your integrity.
