Trigger a MIDI note when releasing a strum

Strum Release

The strum release feature triggers a specific MIDI note when you lift the pen after a quick strum. This is useful for adding percussive hits or accents.

Configuration

{
  "strum_release": {
    "active": false,
    "midi_note": 38,
    "midi_channel": null,
    "max_duration": 0.25,
    "velocity_multiplier": 1.0
  }
}

Properties

Property	Type	Default	Description
active	boolean	false	Enable strum release
midi_note	number	38	MIDI note to send (38 = snare drum)
midi_channel	number|null	null	Channel (null = same as strummer)
max_duration	number	0.25	Max strum duration to trigger (seconds)
velocity_multiplier	number	1.0	Velocity scale factor

How It Works

1. Touch the tablet and strum
2. Lift the pen within max_duration seconds
3. The configured MIDI note is triggered
4. Velocity is based on your strum pressure × velocity_multiplier

If you hold the pen down longer than max_duration, no release note is sent. This prevents accidental triggers during sustained playing.

Example: Snare Accent

Add a snare hit on quick strums:

{
  "strum_release": {
    "active": true,
    "midi_note": 38,
    "max_duration": 0.2,
    "velocity_multiplier": 0.8
  }
}

Example: Hi-Hat

Trigger a hi-hat on release:

{
  "strum_release": {
    "active": true,
    "midi_note": 42,
    "midi_channel": 9,
    "max_duration": 0.15
  }
}
