The Polysix is a 6 voice analog polysynth with VCOs as opposed to the somewhat more familiar DCOs in similar keyboards of the time. This synth has a soft and warm sound likely due to those VCOs. There are also 32 preset slots available, ensemble and chorus effects and an arpeggiator.
This synth is in good working condition and was just serviced with a new replacement CPU main board (from Synthronics.de). Physically there is general overall wear but nothing out of the ordinary for an instrument of this age, worst being the paint pitting on the front panel. LED on program button number 4 is out, but everything else is fully functional (button still operates).
This is a great sounding analog poly that gives more popular synths like the Roland Juno a run for its money.
