If you console.log the note you'll see other internal fields, but '''DO NOT MODIFY THESE'''. | If you console.log the note you'll see other internal fields, but '''DO NOT MODIFY THESE'''. | ||
For example, you can halve the volume like this (eg for a custom delay effect, copy, shift, then tweak the volume): | |||
tweakNotes(n => n.volume *= 0.5) | |||
Another example is the humanize function, which is built on tweakNotes (in fact, several of the other functions could be rewritten in terms of tweakNotes): | |||
function humanize(volumeVariation = 0.2, timeVariation = 0.1) { | |||
tweakNotes(n => { | |||
n.volume *= 1 + volumeVariation * (2 * Math.random() - 1); | |||
n.time += timeVariation * (2 * Math.random() - 1); | |||
if (n.time < 0) n.time = 0; | |||
}); | |||
} | |||
Tweak notes can also be used to generate the lengthening sawtooth effect from [https://onlinesequencer.net/1905746 Ganymede]: | |||
tweakNotes(n => { | |||
n.length *= 0.5 + (n.time - span.min) / (span.max - span.min); | |||
}); | |||
A more complicated example is adding swing to your selected notes: | |||
tweakNotes(n => { | |||
const t = n.time / 4; | |||
const intTime = Math.floor(t); | |||
const fracTime = t - intTime; | |||
const newFracTime = fracTime <= 0.5 ? fracTime * 4 / 3 : (fracTime - 0.5) * 3 / 4 + 2 / 3; | |||
n.time = (intTime + newFracTime) * 4; | |||
}); | |||

With these limitations, the most useful thing you can do is set the marker value to a value outside the normal range (like we did for the instrument settings above). This snippet sets all the selected detune markers to detune up by 2 octaves: | |||
for (const marker of selection.markers) { | |||
if (marker.setting == kMarkerSettingInstrumentDetune) { | |||
marker.value = 2400; | |||
} | |||
} | |||
You can also use "song.getAllMarkersAtTime(t)" to get a list of all the markers at a specific time, but selecting them in the UI and then iterating over "selection.markers" is easier. | |||
