■ This metronome is powerful for practical rhythm training at home or for use on a live stage. It features a pendulum display with a large, backlit LCD for excellent visibility, a variety of training functions, and a note mixing function that lets you create original rhythm patterns. Furthermore, a comprehensive range of connection jacks enhances ease of use.
■ In addition to the basic metronome function of providing a reference beat, it also features a rhythm coach function for effective rhythm training. You can check your rhythmic deviations yourself by connecting a trigger pad such as a Roland V-Pad or using the built-in microphone. Time Check mode lets you visually check the deviation from the reference beat. Gradual Up/Down mode also lets you practice along with beats that gradually change speed. This is useful for developing accurate rhythm keeping and developing rich expressiveness.
■By connecting a foot switch such as the FS-5U or FS-6, you can start/stop and increment/decrement the memory, allowing for convenient control even when you cannot operate the panel.
