KORG MS-20 mini Specification

The KORG MS-20 mini is a compact reissue of the iconic MS-20 analog synthesizer, renowned for its rich, dynamic sound and versatile capabilities. At its core, the MS-20 mini features two voltage-controlled oscillators (VCOs) that deliver powerful and distinctive analog sound generation. These oscillators provide a variety of waveforms, including sawtooth, triangle, and pulse waveforms, allowing musicians to craft a wide range of tones.

A standout feature of the MS-20 mini is its self-oscillating high-pass/low-pass filters with distinctive resonance, which are integral to shaping the sound and have been meticulously replicated from the original 1978 design. The synthesizer also incorporates two envelope generators and a modulation generator, offering extensive modulation possibilities for dynamic sound sculpting.

The MS-20 mini retains the patchable architecture of its predecessor, featuring a flexible patch panel that allows users to explore a multitude of signal routing and modulation options, fostering creativity and experimentation. This semi-modular design encourages hands-on interaction and provides a deep understanding of analog synthesis principles.

The miniaturized design of the MS-20 mini maintains the original’s authentic look and feel, scaled down to 86% of the original size while providing modern enhancements such as MIDI IN and USB connectivity for seamless integration with contemporary music production setups. The instrument is housed in a robust, portable chassis, making it ideal for both studio and live performance environments. With its faithful reproduction of the original circuitry and classic aesthetics, the KORG MS-20 mini stands as a powerful tool for both vintage enthusiasts and modern musicians seeking analog warmth and character.

KORG MS-20 mini F.A.Q.

How do I connect the KORG MS-20 mini to a computer for recording?

To connect the KORG MS-20 mini to a computer for recording, you will need an audio interface. Connect the output of the MS-20 mini to the input of your audio interface using a 1/4-inch cable. Then, connect the audio interface to your computer via USB or FireWire, and set up your DAW to recognize the interface as an input source.

What is the best way to tune the KORG MS-20 mini?

Tuning the KORG MS-20 mini can be done using the VCO1 and VCO2 pitch knobs. Use a tuner or reference pitch to adjust these knobs until the MS-20 mini is in tune. It's advisable to let the synthesizer warm up for a few minutes before tuning for better stability.

How can I create a bass sound on the KORG MS-20 mini?

To create a bass sound, set the VCO1 waveform to triangle or square, and VCO2 to a lower octave. Adjust the filter cutoff to a low frequency, and increase the resonance slightly. Fine-tune the envelope generator to have a short attack and medium decay.

What should I do if the keys on my KORG MS-20 mini are not responding?

If the keys are not responding, check the MIDI settings to ensure it's not in an external control mode. Also, make sure the local control is on. If the problem persists, perform a factory reset by holding certain keys while powering on, as detailed in the user manual.

How do I set up an external audio input on the KORG MS-20 mini?

To use an external audio input, connect the external sound source to the 'External Signal Processor (ESP)' input. Adjust the ESP settings to process the signal, and route it through the patch panel to filter or modulate the sound.

Can I sync the KORG MS-20 mini with other equipment?

Yes, the MS-20 mini can be synced with other equipment using the CV/Gate connections. Connect the CV Out of a sequencer or another synth to the CV In of the MS-20 mini. Use the Gate In to sync note triggering.

What is the function of the patch cables on the KORG MS-20 mini?

The patch cables on the KORG MS-20 mini allow you to reroute internal signals and create complex modulations. By using the patch panel, you can connect different sections like the LFO, envelope generator, and filters to modify the sound in creative ways.

How can I fix noise issues with my KORG MS-20 mini?

If you're experiencing noise issues, check all cable connections for any loose plugs. Ensure that the power supply is stable and that the synthesizer is properly grounded. You can also use the filter section to reduce high-frequency noise by adjusting the cutoff frequency.

What maintenance is required to keep the KORG MS-20 mini in good condition?

Regular maintenance for the MS-20 mini includes dusting the exterior, avoiding exposure to extreme temperatures, and ensuring cables and connections are kept clean. Periodically check for firmware updates from KORG to ensure optimal performance.

How can I use the KORG MS-20 mini with a MIDI controller?

To use the MS-20 mini with a MIDI controller, connect the MIDI Out of the controller to the MIDI In of the MS-20 mini. Ensure that the MIDI channels match on both devices. This allows you to play the MS-20 mini using the MIDI controller's keyboard or pads.
