Optionalfade_How quickly the trail behind the point fades. Lower leaves a longer tail showing where the line has been.

Optionalnote_Note at the end of the strip, as a MIDI number
Optionalnote_Note at the start of the strip, as a MIDI number. A bassline sits around 33-54; a vocal or lead line around 55-84. A narrow range gives bigger, clearer movement.
Optionalpitch_Low-pass the audio before detecting pitch, in Hz. An octave-up error is the detector locking onto the second harmonic, so removing it helps: on a real bassline, 100Hz cut octave errors from 12% to 5%. Set 0 to use the shared detector instead. Only sensible for low sources - leave off for vocals.
Optionalsilence_Level in dBFS below which the stem counts as silent and the point goes dark. A separated stem always carries residue, so this has to be judged on level. Scored against a hand-labelled track, -30 agreed with where the bass actually played 74% of the time and -27 got 82%, while -45 false-lit 87% of the silent passages. Lower it if quiet notes are being cut.
OptionalsmoothingFrames of median filtering. Higher is steadier but lags behind the music: about 67ms at 9 frames, 33ms at 5. Lower it if the line feels delayed against your other effects.
