This tool has amazingly quite latency on my Z1. This is particularly noticeable when you start effect tones, or worse, if you tried to make with the percussion sounds with the rhythm. The GUI is very tidy. There is even the possibility to work with it in portrait mode. With personally lack the ability to create a playlist that (automatically) is then executed. The handling at the start is too cumbersome. so I have to start the player and can sync only then. Because of these points only 3 stars. To play recommended for in between. As a sound machine for the party only limited recommended due to the lack of a playlist.
