Post keyboards, small devices, larger devices, old or new, oscillators, knobs, I/O controllers, wires... anything goes but ANALOG only.
Gah! I have an indescribable love and appreciation for analogue audio equipment. Perhaps it comes from that childlike instinct to push buttons and twiddle knobs.
These make me slightly shameful that I only use a DAW
I think most of this is analog. I think there is synthesizer gear in there somewhere...
