KeyStep 37 mk2 - Control modes – Arturia FAQ

Here is a quick description of the different Control modes offered by KeyStep 37 mk2:

The Arpeggiator is a key component that generates note patterns based on the keys pressed.

Function	Detailed Specifications
Modes	The KeyStep 37 mk2 offers a total of 15 predefined Arpeggiator Modes. These include standard modes such as Up, Down, UpDown, Random, Order, and Poly.
Special Mode 16	Mode 16 is the User Sequence mode, which copies the last played Sequencer Pattern into the Arpeggiator slot.
Note Capacity	You can add up to 64 notes to your Arpeggio using the Hold button and the Octave –/+ buttons.
Octave Range	The range can be extended up to 4 octaves by holding Shift and pressing the Arpeggio Octave keys.
Gate Control	Gate time (note duration) is adjustable from 10% (shortest) to 90% (longest). This setting is independent of the Sequencer Gate settings.
Swing Range	Swing can be set from 50% (equal notes) to 75% (maximum shuffle).
Randomization (Spice)	The Spice function adds randomness to Gate Length, Silence, and Ratchet (multiple triggering). It is controlled by holding Shift and sliding the Modulation Strip.
Conversion	An active Arpeggio can be turned into a Sequencer Pattern by long-pressing the Record button or holding Shift and pressing To Seq.

The KeyStep 37 mk2 Sequencer is polyphonic, allowing for complex musical patterns to be recorded and played back.

Function	Detailed Specifications
Storage Capacity	The sequencer holds a total of 64 sequences, divided into 4 Banks of 16 Patterns in each. Patterns can be saved and swapped using the MIDI Control Center.
Pattern Specifications	Each Pattern can be up to 64 steps long, with polyphony of up to 8 notes per step.
Data Recorded	The Sequencer records notes, the velocity of each note, rests (entered via the Hold* button), and data arriving via MIDI or USB. Automation (Pitch Bend, Modulation, Gate, Spice, Aftertouch*) can also be recorded if enabled.
Data NOT Recorded	The Sequencer does NOT record the note duration (Gate time), Time Division changes, or Swing percentage.
Quantization Strength	Quantization (time-correction for real-time recording) can be set to 50% or 100% corrected.
Editing Functions	Quick modification functions include Nudge (Shift + Nudge keys) to shift the pattern in time, and Double (Shift + Double key) to double the length of the pattern and its events. The Undo feature removes the last recorded step(s).

KeyStep 37 mk2 is a full-featured controller with extensive MIDI, USB, and analog (CV/Gate) connectivity.

Technical Aspect	Detailed Specifications
Keyboard Sensitivity	The controller features a Slimkey keyboard equipped with Velocity and Aftertouch (pressure sensitivity). Velocity and Aftertouch curves can be set to Linear, Logarithmic, or Exponential.
CV Pitch Formats	Two formats are supported: Volt/Octave (0–10V) and Hertz/Volt (maximum ~12V).
CV Pitch Reference	The MIDI note that sends 0 Volt CV output is selectable, with options: C–2, C–1, C0, C1, C2, or C3.
Gate Format	The Gate output signal is configurable to S-trig, V-trig 5V, or V-trig 12V for compatibility.
CV Modulation Outputs (Mod 1/2)	The two Mod outputs send Control Voltage signals. The signal source can be selected from Velocity, Aftertouch, Modulation Strip, Random, Envelope, LFO or Pulse. All these settings can be controlled via the 4 control knobs (with "Control" mode enabled).
Mod Voltage Range	The maximum voltage sent via the Mod 1/2 CV Outputs is adjustable from 1–10 Volts.
Touch Strip Behavior	The Pitch Strip snaps back to zero when released. The Modulation Strip does NOT snap back to zero when released, meaning modulation continues until manually returned to zero.
Pitch Bend Range	The range of the Pitch Touch Strip can be specified from 1–24 semitones.
