KORG MS-20 Specification

The KORG MS-20 is a monophonic analog synthesizer renowned for its distinctive sound and flexible architecture. Originally launched in 1978, the MS-20 has been reissued in modern times, preserving its classic appeal while incorporating contemporary enhancements. The synthesizer features two Voltage Controlled Oscillators (VCOs) which provide a range of waveforms, including sawtooth, triangle, and pulse, allowing for rich tonal diversity. The MS-20 is equipped with a self-oscillating Voltage Controlled Filter (VCF) section, comprising both high-pass and low-pass filters, known for their sharp resonance and ability to generate complex sound textures.

The instrument's patchable design is a standout feature, enabling users to explore modular synthesis without additional modules. It includes inputs and outputs for external signal processing, offering immense flexibility in sound manipulation. The envelope generators onboard consist of two ADSR envelopes that give precise control over sound shaping. Additionally, the LFO (Low-Frequency Oscillator) section provides multiple waveform options to modulate various parameters, contributing to the MS-20’s dynamic sound capabilities.

The MS-20 reissue maintains the original analog circuitry, ensuring authentic sound reproduction. It includes MIDI and USB connectivity, integrating seamlessly with modern studio environments while preserving its vintage charm. The synthesizer's compact design makes it suitable for both studio and live performances, appealing to musicians who value portability without compromising on sound quality. With its robust build and iconic design, the KORG MS-20 continues to be a favored choice among electronic musicians, offering a blend of historical significance and contemporary utility.

KORG MS-20 F.A.Q.

How do I connect the KORG MS-20 to external audio equipment?

To connect the KORG MS-20 to external audio equipment, use the output jack on the rear panel. Connect a patch cable from the output jack to the input of your audio interface or amplifier. Ensure the volume levels are appropriate to avoid distortion.

What is the best way to maintain the patch cables for the MS-20?

Regularly check the patch cables for any signs of wear or damage. Store them coiled loosely to avoid kinks and tangles. Cleaning the connectors with a contact cleaner can prevent oxidation and ensure a solid connection.

How can I troubleshoot if the MS-20 is not producing any sound?

First, check all cable connections and ensure the power is on. Verify that the volume is turned up and the patch connections are correct. If using headphones, ensure they are properly connected. If no sound is produced, try resetting the synth to its initial patch settings.

Can I use the KORG MS-20 with other MIDI devices?

The original MS-20 does not have MIDI capabilities. However, the MS-20 Mini and other reissues come with MIDI input and USB connections, allowing them to interface with MIDI devices and DAWs.

How do I clean the exterior of the KORG MS-20?

Use a soft, dry cloth to wipe down the exterior. For stubborn dirt, lightly dampen the cloth with water. Avoid using solvents or abrasive cleaners as they can damage the finish and components.

What should I do if some keys on my MS-20 are not responding?

Check if the keys are physically obstructed. If they are clean, the issue might be internal. Opening the unit and cleaning the contacts with a contact cleaner may resolve the problem. If uncertain, consider professional servicing.

How do I create a basic lead sound on the MS-20?

To create a basic lead sound, set both oscillators to square waveforms. Adjust the cutoff frequency to shape the sound, and use the envelope generator to control the attack and decay for the desired effect.

Why is my MS-20 out of tune?

Analog synthesizers like the MS-20 can drift out of tune due to temperature changes. Allow the synth to warm up for a few minutes before playing. If the issue persists, calibrating the oscillators may be necessary. Consult the manual or a technician for detailed instructions.

Can I use the MS-20 for bass sounds?

Yes, the MS-20 is capable of producing rich bass sounds. Use a low-pass filter to focus on the lower frequencies and adjust the resonance for added texture. Experiment with the envelope generator to shape the bass sound further.

How do I update the firmware on the MS-20 Mini?

Download the latest firmware from the KORG website. Connect the MS-20 Mini to your computer via USB, and run the firmware update utility, following the on-screen instructions to complete the update.
