Control how long notes sustain

Note Duration

Note duration controls how long each note sustains before the note-off message is sent.

Configuration

{
  "note_duration": {
    "control": "tiltXY",
    "min": 0.15,
    "max": 1.5,
    "curve": 1.0,
    "spread": "inverse",
    "default": 1.0
  }
}

Common Setups

Tilt-Controlled Duration

Tilt your pen for longer or shorter notes:

{
  "note_duration": {
    "control": "tiltXY",
    "min": 0.1,
    "max": 2.0,
    "spread": "inverse"
  }
}

With "inverse" spread, holding the pen upright gives longer notes, tilting gives shorter staccato notes.

Fixed Duration

All notes the same length:

{
  "note_duration": {
    "control": "none",
    "default": 0.5
  }
}

Pressure-Controlled Duration

Press harder for longer notes:

{
  "note_duration": {
    "control": "pressure",
    "min": 0.1,
    "max": 1.0,
    "spread": "direct"
  }
}

Duration Range

  • min: Shortest possible note (in seconds)
  • max: Longest possible note (in seconds)

Typical ranges:

  • Staccato: 0.05 - 0.2 seconds
  • Normal: 0.2 - 1.0 seconds
  • Legato: 0.5 - 2.0 seconds
