KORG POLY-800 Specification

The KORG POLY-800 is a vintage analog synthesizer known for its distinctive sound and compact design. Released in 1983, it features a polyphonic architecture with eight voices, each capable of generating two digital oscillators. The oscillators can be combined in various ways, with options for sawtooth, square, and pulse waveforms, enabling a range of sound textures. The POLY-800 includes a single low-pass digitally controlled filter, which can be adjusted for resonance and cutoff frequency, providing users with sound-shaping capabilities.

One of the unique aspects of the POLY-800 is its ability to reverse the filter envelope, allowing for more creative modulation possibilities. The synthesizer also includes a chord memory function, enabling the storage and recall of chord shapes, which is particularly useful for live performance settings. The instrument's envelope generator has five stages, allowing for intricate control over sound dynamics. Its onboard sequencer can store up to 256 notes, facilitating complex musical compositions.

The POLY-800 is equipped with a MIDI interface, which was a novel feature at the time of its release, allowing for integration with other MIDI-capable devices. The interface supports basic MIDI functions, enhancing the synthesizer's versatility in a digital music setup. The synthesizer is powered by both AC and battery options, making it suitable for portable use. Despite its limited control panel, the POLY-800 offers deep programmability through parameter editing. Its compact and lightweight build, coupled with its robust sound capabilities, has maintained its popularity among synthesizer enthusiasts and collectors.

KORG POLY-800 F.A.Q.

How do I perform a factory reset on the KORG POLY-800?

To perform a factory reset on the KORG POLY-800, turn off the synthesizer. Press and hold the 'Write' button while turning the power back on. Continue holding the 'Write' button until you see the reset confirmation on the display.

What should I do if my POLY-800 is not producing any sound?

First, ensure all cables are properly connected and the volume is turned up. Check that the synthesizer is not in a muted state. If the issue persists, consider performing a factory reset or checking for internal hardware issues.

How can I change the battery in my POLY-800?

To change the battery, turn off and unplug the synthesizer. Remove the screws from the bottom panel and carefully open it to access the circuit board. Locate the battery holder, remove the old battery, and insert a new one. Ensure the polarity is correct before reassembling.

How do I connect the POLY-800 to an external MIDI device?

Connect a MIDI cable from the MIDI OUT of your external device to the MIDI IN of the POLY-800. Make sure both devices are set to the same MIDI channel to ensure proper communication.

What is the process for saving and loading patches on the POLY-800?

To save a patch, press 'Write', select the desired memory location, and confirm by pressing 'Write' again. To load a patch, press 'Load' and select the patch number you wish to load.

Why does my POLY-800 power off unexpectedly?

Check the power adapter and connection for faults or loose connections. If using batteries, ensure they are not depleted and seated correctly. If the problem continues, inspect for internal power supply issues.

How can I improve the sound quality of my POLY-800?

Experiment with adjusting the filter, resonance, and envelope settings. Additionally, consider using external effects processors for reverb, delay, or chorus to enhance the sound.

Can I upgrade the firmware on my KORG POLY-800?

The KORG POLY-800 does not support firmware upgrades as it is an analog/digital hybrid synthesizer from the 1980s. Any updates to functionality would require hardware modifications.

How do I use the sequencer on the POLY-800?

To use the sequencer, press the 'Seq' button and enter your sequence using the keyboard. Use the step buttons to navigate through the sequence. Press 'Play' to start the sequence playback.

What maintenance does the POLY-800 require?

Regularly check and clean the keys and knobs to prevent dust build-up. Inspect cables and connections for wear and replace them as needed. Periodically test the battery and replace it to preserve memory functions.
