No, vArranger own internally 2 independant engines to play Ketron styles and Yamaha styles. There is no conversion. The goal was to play Ketron styles exactly as played on a Ketron Keyboard, and Yamaha styles as played by Yamaha Keybs. You must know that Yamaha and Ketron have internally a very different way to generate the automatic accompaniment. Any conversion will remove some parts of the Styles.
