My hobby started out as a DIY music production thing, but more recently I've found myself really interested in the tech itself and I hope to one day have a proper sound system set-up.
I am still very interested in the musician side though, and a lot of my purchases come from that angle. I just bought a used Edirol R1 recorder to try and break away from recording and playing everything through my laptop. Still need to invest in some better speakers though.
