Roland MKS-80 Super Jupiter Synthesizer

The MKS-80 is an 8 voice, 16 VCO polyphonic synthesizer module that can be played by MIDI.
The MKS-80 has memory capacity that retains 64 different tone colors. By using the Memory Cartridge M-64C that retains up to 128 tone colors, total of 192 patch programs can be available.
The MKS-80 features battery backup system that retains the data in memory even when switched off.
Auto Tune function that allows all VCO's to be instantaneously tuned just by pressing a button.
Patch Preset is a program that can contain a tone color (or even a pair of tone colors depending on the Key mode setting) and various mode and effect settings.
The Detune function enables a powerful ensemble effect in Unison mode.
The Octave Shift function allows shifting the pitch of the entire keyboard without changing the VCO range.
Data in the MKS-80's memory can be transferred to another MKS-80 or to a computer.
The MKS-80's dynamics function can change the attack time as well as the level.
By the unique Envelope Reset function, each time you press a new key, the note will start from the beginning of the envelope curve.
As the MKS-80 is a vintage model I will not except any returns. The unit is working perfectly and I checked them with a midi keyboard through an amp and speakers as well as through the front headphone jack."
