+- `E8xy`: **Quick legato up**. transposes note up by `y` semitones after `x` ticks.
+- `E9xy`: **Quick legato down**. transposes note down by `y` semitones after `x` ticks.
 - `00xy`: **Arpeggio.** this effect produces a rapid cycle between the current note, the note plus `x` semitones and the note plus `y` semitones.
 - `E0xx`: **Set arpeggio speed.** this sets the number of ticks between arpeggio values. default is 1.
