My hobbies are anything computer-related (tinkering, fixing, building), and doing sound (live or studio recording). It is an amazing feeling taking the talents of a group of musicians and singers and sculpting and mixing the sounds and effects into something much more than the sum of its parts. When someone asks me if I play an instrument, I respond with: "Yes, I play the mixer!"
I worked as a computer network administrator for years so I've done a lot of the fixing and building but it was work, not a hobby . In fact, now I don't even want to think about doing anything on them other than playing with my labels.
My brother runs a radio station and does some music production as well, so I've seen how much work it takes to edit and mix! It also takes a lot of talent, so kudos to you!
