Hello all, new here. Hoping this is the right place for such inquiries. I recently acquired an E-MU “Vintage Keys” keyboard that I know next to nothing about. Got it home and plugged it in. Turns on and lights up but no sound. Upon further inspection I noticed there’s a panel door that is missing from the bottom of the unit. It looks to me like there’s something missing. I’ll attach some photos. iCloud
Does anyone know what’s missing to make this unit work and is it attainable? Any other knowledge or opinions of the unit are more than welcome and greatly appreciated!
