It features a 32-note SlimKey keyboard with velocity and aftertouch for nuanced playing, along with an OLED display and push encoder for intuitive navigation of sequencing and setup functions. The polyphonic step sequencer allows for real-time or step-time recording with support for rests, ties, and up to 8 voices per step, enabling you to chain patterns to create full tracks. Additionally, the arpeggiator offers 16 modes, and performance tools like Mutate, Spice & Dice provide one-touch mutation, randomized accents, and variable step lengths for creative unpredictability. This controller also includes CV/gate connectivity and classic DIN-MIDI, making it a flexible choice for synth and modular setups, as well as a great tool for discovering new musical patterns. It comes bundled with a software package including a DAW and a large sound library.
The Arturia KeyStep MK2 is a compact MIDI keyboard controller and sequencer for musicians seeking versatile creative control. Its primary benefit is enabling nuanced performance and complex pattern creation in a portable package. A potential caveat is its compact keyboard size, which may require adjustment for players accustomed to full-sized keys. Key features include a 32-note velocity and aftertouch-sensitive keyboard, a powerful step sequencer, an intuitive arpeggiator, and flexible connectivity options for both modern and vintage setups.

How do I connect the KeyStep MK2 to my modular synthesizer?
Use standard 3.5mm TS or TRS cables to connect the CV (Pitch, Mod, Vel) and Gate outputs from the KeyStep MK2 to the corresponding inputs on your modular synth modules.
Does the KeyStep MK2 send Aftertouch messages?
Yes, the SlimKey keyboard is equipped with aftertouch, allowing for expressive control of parameters such as vibrato or filter sweeps after a note has been initially pressed.
What software is included with the KeyStep MK2?
The KeyStep MK2 typically comes bundled with a selection of Arturia's software, which may include a DAW (like Ableton Live Lite) and a sound library (like Analog Lab Intro) for immediate music creation.
How many patterns can the sequencer store?
The KeyStep MK2 allows you to chain patterns together and offers significant pattern storage, enabling the creation of longer musical arrangements.
Can I control multiple synths simultaneously?
Yes, you can control multiple synths by using the MIDI Out port and USB connection simultaneously, and by routing CV/Gate signals to different modules or instruments.
Troubleshooting
Device not recognized by computer
Ensure the USB cable is securely connected at both ends. Try a different USB port on your computer. Restart your computer and the KeyStep MK2. Download and install the latest drivers from the Arturia website if available.
No MIDI output from USB
Verify that the KeyStep MK2 is selected as a MIDI input device within your DAW's preferences. Check that the correct MIDI channel is selected on the KeyStep MK2.
Keys are not responding to velocity or aftertouch
Ensure velocity and aftertouch are enabled in the KeyStep MK2's settings menu. Check that your connected software or hardware is configured to receive velocity and aftertouch data.
Sequencer is not playing back
Ensure a sequence has been recorded. Check that the play/stop button is engaged and that the tempo is set appropriately. Verify that the MIDI output routing is correctly configured in your DAW or hardware.
CV/Gate outputs are not sending signals
Confirm that the CV/Gate settings (e.g., voltage range, gate type) in the KeyStep MK2's menu match the requirements of your modular system. Ensure the device is set to a mode that utilizes these outputs.
