The Planet-S MKS-30 from Roland is essentially a rackmountable version of the iconic JX3P analog polyphonic synthesizer. It offers six voices of fabulous analog polyphony and luscious stereo chorus. It can be played using any MIDI controller, but sound editing must be done with the use of a PG200 or similar controller via the front panel 6 pin DIN input.

This used unit is in good cosmetic condition with a few minor scratches, pictured. There is a slight crackling sound that can be heard from the outputs, which is a common issue with this product. It is priced to reflect this defect.
