KORG POLY-800II Specification

The KORG POLY-800II is an enhanced version of the original POLY-800 synthesizer, which is known for its portable design and distinctive sound characteristics. It features an 8-voice polyphony and a 49-key keyboard, allowing for expressive performance capabilities. The synthesizer utilizes digitally controlled oscillators (DCOs) to generate sound, with each voice having one DCO and the ability to produce sawtooth, pulse, and square waveforms. It includes a resonant filter section with a low-pass filter that provides dynamic sound shaping capabilities, further enhanced by an adjustable cut-off, resonance, and envelope modulation.

The POLY-800II is equipped with a built-in digital delay effect, which adds depth and space to sounds, a significant upgrade from its predecessor. The synthesizer's modulation options include a single LFO for controlling pitch and filter, and a comprehensive envelope generator that can be assigned to both amplitude and filter settings. The unit also supports MIDI functionality, enabling integration with other MIDI-equipped instruments and devices for expanded performance and production possibilities.

A memory capacity for storing up to 64 user patches allows for quick recall of customized sounds, facilitating ease of use in live and studio settings. The interface includes a simple, menu-driven parameter access system, making sound editing intuitive despite the absence of extensive real-time control knobs. The POLY-800II's compact and lightweight design, powered by either an external adapter or batteries, makes it ideal for mobile musicians. Overall, the KORG POLY-800II offers a blend of vintage charm and modern utility, appealing to both nostalgic enthusiasts and contemporary producers seeking unique sound textures.
