It is surely not the time you spent to learn to understand the technics and its possibilities.
The rewarding part happens once you get familiar with the digital tool and you transcend it. Then you realize that you do not play an instrument anymore...but you make music.
I always liked to combine different styles and interacting with the machine, playing some kind of ping pong, chasing aesthetic phantoms in the magnetic field of a hard drive is an exciting experience. Also, as randomness plays an interesting part in the process, one has to be open to surprises to catch on or conversely not to include them and go backwards to try another direction.
That's what I like about digital tools.
