My total for the year came out to about $1550 and change, which isn't a huge amount obviously but nothing to sneeze at either. Heck, it just about exactly paid for my Soma Terra, and that's the most expensive standalone synth I own. It's also about 5x what I made the year before.
Turns out doing stuff like sales and promoting to a willing and appreciative listener base who believes in supporting art makes a difference.
