PIANO ROLL
Piano roll Chopper 
The Piano roll Chopper is an advanced note slicing tool that can use standard score files as slicing templates.
Options
1. Pattern
The Piano roll Chopper uses standard FL Studio Score files (*.FSC) as slice patterns . Click the Browse button to select a groove template.
The Piano roll shows real-time preview of the results. See below for some guides about making such patterns.
2. Options
This section lets you set the options that will be used for slicing.
- Time Multiplicator knob - With this setting you can speed up (turn left) or slow down (turn right) the pattern tempo. The chopper uses the original pattern speed by default.
- Absolute Pattern switch - When switched on, slicing is based on the Piano roll grid. When switched off, each note is sliced relative to its start time (see the example image below).
- Levels knobs - With these controls you can mix the original note properties (turn left) with those used in the chop pattern (turn right).

3. Apply button
Applies the changes to the Piano roll score.
Guides for making Chopper patterns
The templates are regular Piano roll scores, however they are interpreted in a special way to fit the purposes of the tool.
- Pitch is not ignored, so this can be used to create transposed melodies out of a chopper preset using a single root note.
- A yellow note is ignored for chopping, so it can be used to define the length of the pattern, which is useful to fine-tune the length of looped patterns.
- The start of the score matches start of the processed score in absolute pattern mode, and start of each individual note relative pattern mode (absolute mode off).
