So, a few weeks ago I was about to post to ask for tips on cable management. And when typing I came up with the solution that would work for me. Simply to put an Ikea picture ledge (actually two) situated 15 cm below my desk.
This seems to work really well. It cleans up my desk, everything stays accessible and removeable (if to be brought somewhere) and it also gave me some extra storage space for small synths and gadgets. I figured I’d share it so it could help someone else too.
