Product Information

Full details

The Arturia KeyStep 37 MK2 is a compact and versatile 37-key MIDI controller and sequencer designed for musicians using hybrid setups. Its primary benefit is offering a powerful toolkit for both live performance and detailed music production, with expressive controls and generative sequencing capabilities. A potential caveat is its 37-key range, which may be limiting for those requiring extensive melodic range without octave shifts. Key features include a velocity-sensitive Slimkey keyboard with aftertouch, a polyphonic step sequencer, a 16-mode arpeggiator, and innovative Chord and Scale modes, complemented by Mutate, Spice, and Dice tools for creative pattern manipulation. Four encoders and an OLED display ensure intuitive control, while extensive connectivity options make it a central hub for modular synths, hardware, and DAWs.

FAQs

Can I use the KeyStep 37 MK2 as a standalone sequencer without a computer?

Yes, the KeyStep 37 MK2 can function as a standalone sequencer. It can be powered via USB or an optional power supply and can sequence external hardware synthesizers and modules without needing a computer connected.

What is the difference between the Arpeggiator and the Sequencer modes?

The Arpeggiator generates melodic patterns based on held notes and selected modes, ideal for rhythmic embellishments. The Step Sequencer allows you to manually program each step of a sequence, offering more precise control over melody and rhythm.

How do the Mutate, Spice, and Dice functions work?

These functions add generative variations to your sequences. Mutate subtly alters the sequence, Spice adds rhythmic or melodic complexity, and Dice randomly reconfigures elements of the sequence, providing creative exploration tools.

What kind of synthesizers can I connect using the CV/Gate outputs?

You can connect any analog synthesizer or modular synth system that accepts Pitch CV, Gate, and Modulation CV signals. The KeyStep 37 MK2 provides these standard outputs for broad compatibility.

Does the KeyStep 37 MK2 come with software?

The KeyStep 37 MK2 is compatible with Arturia's MIDI Control Center software, which can be downloaded for free from the Arturia website. This software is used for firmware updates and deeper customization of the device's settings.

Can I use the KeyStep 37 MK2 to control multiple devices simultaneously?

Yes, you can send MIDI and CV/Gate signals to different devices by configuring the output channels and modes accordingly. This allows for complex setups where one controller manages multiple sound sources.

Troubleshooting

No sound from connected synth

Verify MIDI cables are correctly connected. Ensure the correct MIDI channel is selected on both the KeyStep 37 MK2 and the synth. Check that the synth's audio output is properly connected to your monitoring system.

Sequencer not triggering notes

Confirm the sequencer is armed and playing. Check that the correct sequence length and tempo are set. Ensure CV/Gate or MIDI output settings match the receiving device's configuration.

Device not recognized by computer

Try a different USB cable or USB port. Ensure you have the latest firmware installed via the MIDI Control Center. Restart both the KeyStep 37 MK2 and your computer.

Aftertouch not working as expected

Ensure aftertouch is enabled in the settings. Experiment with the pressure sensitivity to find your preferred level. Check if the synth or DAW receiving the signal is configured to interpret aftertouch data.

Pros and Cons

  • Highly versatile for both sequencing and keyboard control.
  • Intuitive creative tools (Mutate, Spice, Dice) for generative music.
  • Compact size ideal for studio desks and live setups.
  • Robust connectivity options for diverse setups.
  • Expressive performance capabilities with aftertouch.

Cons

Setup, Compatibility & Care Instructions

Setup:

Connect the KeyStep 37 MK2 to your computer via USB-C for power and MIDI communication with your DAW. For hardware setups, use the appropriate MIDI DIN or CV/Gate cables to connect to your synthesizers or modules. The Sync I/O can be used to link multiple Arturia sequencers or external clock sources.

Compatibility:

This controller is class-compliant and works with macOS, Windows, and Linux. It is compatible with all major DAWs and any hardware synthesizer or modular system that accepts MIDI or CV/Gate signals. The Arturia MIDI Control Center software (downloadable from Arturia's website) allows for deeper customization of settings and firmware updates.

Care:

Keep the unit away from liquids and extreme temperatures. Clean the surface and keys with a dry or slightly damp microfiber cloth. Avoid using harsh chemicals or abrasive cleaners. Ensure ventilation around the unit is not obstructed.
