1983 Roland Jupiter 6 (Serial No. 322327)

The Jupiter 6 is a fantastic analog polysynth that's a little bit of an underdog compared to its siblings the 4 and the 8! However, it is very powerful and is likely overlooked due to the immense fame of the others. Its a dual VCO 6 voice with cross mod capabilities, sync, and triangle, square and saw waveforms. The filter section includes standard low pass but also band pass and high pass operation. The filter envelope routing is not preset so envelope 1, 2, or both can be assigned to control the it! The LFO section is fully featured including a random output and onset delay. Of course there is full preset saving and plenty of performance oriented controls. The one downside is that it does not include chorus or ensemble like many of the other Roland polys! It does have the coolest color scheme and those futuristic aluminum sides though. The external analog ins include arpeggiator clock in, patch shift, pedal hold and CV for the VCA and VCF. Of course it has MIDI as well so there is tons of interfacing available. 

This synth is in great working condition and was just serviced by our in house technician.
