Maths takes the art out of music
Don't know about that. Whilst no one wants to hear self satisfying geekcore, knowing the ins and outs of the nature of sound and psycho-acoustics gives you power to wield.

Not sure how possible it is too produce at a decent standard without having a decent working knowledge of computing and sound. Unless you can hire an uber geek engineer of course, then you don't need to learn diddly squat.

Oh, for an engineer...
