X/Y pads are well known for entering modulation data on 2 dimensions. But during a live performance there are so many things to control that you might not want to stay focused on that X/Ypad. With the Loopomat you can play in some variation and loop it with one press.
You can change the start- and endpoint of your recorded loop, the speed of the playback, the direction (foreward/backward), and the range of values for each axis. The routing is done by drop down menus, so it is easy to change the Midichannel and Controllernumber on the fly.
