🟦MIDI notes

  MIDI notes

Creates “laser harp” style effects where incoming MIDI notes trigger beams or shapes across a range. The node uses whatever content you pass into it as the source for each note - feed it a dot, and you’ll get a row of dots. Feed it a shape like a circle, and you’ll get a row of circles, and more complex shapes will be replicated just the same.

You can choose which MIDI interface Liberation listens to in Liberation → Settings (CMD/CTRL ,)

• midi channel – which MIDI channel to listen to (0 = all channels, 1–16 = specific channel)

• width – total width that the notes spread across.

• midi note min / max – the lowest and highest MIDI note values in the range.

• ignore out of range notes – filters out any notes beyond the set range. If disabled, out-of-range notes are "clamped" to the nearest available note (high notes trigger the top of the range, low notes trigger the bottom).

• auto extend range – automatically widens the range if notes are played outside of it.

Not sure what range of notes you’re getting? Switch on auto extend range, set midi note min really high and midi note max really low, then play through your notes. The system will catch them all and expand the range for you. Once you’ve got everything, just turn auto extend range off to lock it in.

• leave all notes visible – creates beams or shapes for all notes in the range whether or not they’re playing, giving you a “laser harp” effect.

• hit colour – the colour that appears when a note is triggered.

• hit colour hold time – how long the hit colour stays at full brightness before fading. Value is in seconds (0–1). 100% = 1 second.

• hit colour decay time – how long it takes the hit colour to fade back after the hold time. Value is in seconds (0–1). 100% = 1 second.

If your content is already pure white, setting the hit colour to white won’t make any difference. For the best results, use a saturated colour for your content and set the hit colour to white - this gives a really nice flash effect when notes are triggered.

• note off fade out time – how long it takes the note to fade after being released. Value is in seconds (0–1). 100% = 1 second.

• hit scale factor – how much the note scales up when triggered (e.g. 2 = double size).

• hit scale hold time – how long the note stays scaled up before shrinking back. Value is in seconds (0–1). 100% = 1 second.

• hit scale decay time – how long it takes for the note to return to its original size. Value is in seconds (0–1). 100% = 1 second.

• note off shrink time – how long it takes to shrink back to original size after the note has been released. Value is in seconds (0–1). 100% = 1 second. (Has no effect when leave all notes visible is enabled.)

Scaling - Note that if your content is a single dot then the scaling will have no effect!
