Notes node
Note Filter
A gate on which notes get through, combining a scale/key filter, a pitch range, and a percent chance — a note only passes if it clears all three checks.
What it does
Note Filter is a note node: it makes, filters or changes notes before a synth plays them. It takes notes in and gives notes out.
Try it
Set a low chance percentage to turn a busy MIDI part into a sparse, randomly-thinned one.
