This pane lets you customize the different playing styles/parts of the instrument. Each one can be positioned at a specific keys range and set to specific parameters. You can either select a preset that already has certain styles that can be triggered using different keys or you can manually select a set of keys in the keymaps window and have as many playing styles as the no. of keys selected. These styles can be added sequentially, that all in one row or it could be added as seperate rows for better control.
