Last October I wrote a post about not having a dedicated work/studio space in my house for a couple of years due to ongoing renovations and posted a picture of the place that would become my new little studio space.
In the past I've often had a whole room or a decent area of a room just for working and to permanently leave my music equipment set up. For the last two years, I've had no dedicated space. Soon I will have a space again and I think I'll appreciate it a lot more this time!
My current music creation setup is centred around Ableton Live on my MacBook Pro, but this is a fairly recent development for me.
