This vintage Roland Jupiter 4 synthesizer is in decent condition for its age. It turns on and works, although I can’t get “musical” sounds out of all of the presets (although I can get some sort of sounds out of them) and options (this may well be because I don’t know how to operate it or set it up). Lots of the settings just seem to make noise, but again, that may be because I don’t know what I’m doing (or it may mean at it needs servicing or that parts of it don’t work right). The Voice and Force presets seem to work fine, and they sound pretty cool. Some of the buttons seem to stick, but they’ll pop out if you try. The switch for the LFO – Manual/Mod setting is broken; see photos. The broken switch is included.
The previous owner was kind of a mad scientist organ player who owned just about everything Roland made in the ’70s and ’80s. He modified this synthesizer with some sort of a slider control on he left side of the keyboard; see photos. I have absolutely no idea what it does, but the synth seems to work anyway. The owner’s manual, a photocopy of the service notes, and some emails regarding the synth are included. The hand-written notes on the owner’s manual are hard to read, but they appear to refer to new memory being installed in 3-89; see photos. I have no idea if any additional memory was actually installed and I don’t guarantee in any way that it was; however, the manual was included with the synth when I got it, and I do know that the handwriting on the manual is the same as handwriting on other things by the same previous owner.
Overall, this Jupiter 4 synthesizer is in pretty good condition for its age. It has some scratches, tape, stickers, and marks from where tape and stickers were placed and removed before. It may need servicing (and I think it probably does), and I do not guarantee that all aspects of it work. This is a vintage, used instrument, and it is sold “as-is.” Click here to visit listing on eBay
