Grids: Key, Time
The Flip tool is used to invert note in time and pitch. First select a series of notes with the Select tool, then click and drag on them with Flip to perform an inversion. If the time grid is on, the note start times will be locked to the grid. If the key grid is on, the note pitches will be locked to the current key.
The shape is a stepper that can be drawn in directly for custom envelopes. First make sure to move the % value above the default of 0.
