Roland MKS-30 Planet-S 80's Polyphonic Synthesiser 2U Rack Mount 240V *Serviced*

The MKS-30 is often refered to as a MIDI rack mount version of the JX3P. Interestingly, the circuits are a bit different, and unlike the JX3P, the MKS-30 uses the same "Voice Chips" as the Juno-106!

The MKS-30 is a 2U rack mount, analogue synthesiser with two DCO's per voice, six voice polyphony, it responds to velocity, and has 64 internal memory patches. The typical assortment of analogue filter, envelope, LFO and oscillator sections are here with easy and straight-forward programming. It can be controlled by the PG-200 programmer (not included in sale) for easier hands-on tweaking. 

Condition: 

  • This is a used unit. 

  • Physically this unit is in good condition. It shows some general wear from use and age like some rack rash, nicks, scratches and scuffs. One rack ear is chipped. A previous owner has engraved their name on the back. There is nothing major and overall it is still a nice synth!

Good looking shoe.
Size: 9 Wide, Color: Cognac
It's a good looking should which is true to size. Quality is good. However, it is not leather. Inner and outer covering are man made. For me, it's okay. I ordered a 9W which I knew would be no more than a triple E width. I'm actually a quadruple E width so it's taking a little longer to break in. I won't be using these as often as at this stage of my life, I don't have that have functions that require dressier shoes. I'm happy with this purchase, a good value for the price. The slip in feature works well like my Sketcher slip in.
