The Korg MS-20 is a legendary monophonic synthesizer that has been a favorite among musicians and sound designers since its release in 1978. Known for its raw, gritty sound and flexible patch bay, the MS-20 is a powerful tool for creating everything from deep basslines to screaming leads. If you’re new to the MS-20, this tutorial will guide you through the basics and help you unlock its full potential. Let’s dive in!

Step 1: Getting Started

  1. Power Up: Connect the MS-20 to power using the included adapter. Turn it on using the power switch.
  2. Familiarize Yourself with the Interface: The MS-20 features two oscillators, a filter, an envelope generator, an LFO, and a patch bay. Take a moment to explore the layout.

Step 2: Playing Notes

  1. Select a Waveform: Use the OSCILLATOR 1 and OSCILLATOR 2 knobs to select a waveform (sawtooth, square, triangle, or noise).
  2. Adjust the Pitch: Use the FREQUENCY knobs to adjust the pitch of each oscillator. You can also use the MASTER TUNE knob to fine-tune the overall pitch.
  3. Play the Keyboard: Use the keyboard to play notes. The MS-20 is monophonic, meaning it can only play one note at a time.

Step 3: Shaping the Sound with the Filter

  1. Select a Filter Type: Use the FILTER TYPE switch to choose between low-pass and high-pass filters.
  2. Adjust the Cutoff and Resonance: Use the CUTOFF FREQ and PEAK knobs to shape the tone of your sound. The filter is one of the MS-20’s standout features, offering everything from smooth sweeps to aggressive squelches.

Step 4: Using the Envelope Generator

  1. Set the Envelope: Use the ENVELOPE GENERATOR knobs to adjust the attack, decay, sustain, and release of your sound. This controls how the sound evolves over time.
  2. Apply the Envelope to the Filter: Use the EG 1 > CUTOFF FREQ knob to apply the envelope to the filter, creating dynamic changes in tone.

Step 5: Adding Modulation with the LFO

  1. Select an LFO Waveform: Use the LFO WAVE FORM switch to choose a waveform (triangle or square).
  2. Adjust the LFO Rate: Use the LFO RATE knob to set the speed of the LFO.
  3. Apply the LFO to the Oscillators or Filter: Use the LFO > PITCH or LFO > CUTOFF FREQ knobs to add modulation to the pitch or filter, creating vibrato or filter sweeps.

Step 6: Exploring the Patch Bay

  1. Connect Patch Cables: Use the patch bay to connect different modules with patch cables. This allows you to create custom signal paths and unique sounds.
  2. Experiment with Patches: Try patching the envelope generator to the oscillators for dynamic pitch changes, or patch the LFO to the filter for rhythmic sweeps. The possibilities are endless.

Step 7: Using External Audio

  1. Connect an External Audio Source: Use the EXTERNAL SIGNAL IN jack to connect an external audio source (e.g., a guitar or drum machine).
  2. Process the Audio: Use the MS-20’s filter and envelope generator to shape the external audio. This is a great way to add unique textures to your sound.

Tips for Success

  • Experiment with Patches: The patch bay is one of the MS-20’s most powerful features. Don’t be afraid to experiment with different connections.
  • Use the Manual: The MS-20’s manual is a great resource for diving deeper into its features.
  • Join the Community: The MS-20 has a dedicated community of users who share patches and tips. Online forums and YouTube tutorials are great resources for learning.
