Korg PS-3300

The Korg PS-3300 is a polyphonic analog synthesizer released by Korg in 1977. It was released alongside the PS-3100, a more compact variant featuring a complete synthesizer voice board for each of its 48 keyboard notes. The PS-3300 essentially combines three PS-3100 units, triggering all voices simultaneously with each key press and mirroring the PS-3100's overall design, featuring a total of 144 synth voices. The PS-3300 uses the PS-3010, a detachable keyboard equipped with an assignable joystick called the X-Y Manipulator.

The PS series also includes the PS-3200, launched in 1978, which upgrades to two voices per key and introduces the capability to save and recall 16 presets. The PS-3200 also substitutes the resonators found in the PS-3100 and PS-3300 with a 7-band equalizer.
