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. |
