Options
Open the Options menu to find some useful quick presets.
- Multiply - Modifies the length of the individual notes as a percentage of their length (10% to 100%)
- Use Lengths - If enabled, the length is calculated using the original notes' length, otherwise the length is computed so that the notes run in succession without gaps ("legato").
- Variation - Randomizes the length using the specified amount.
