A triangle shows the current beat position and the timing in which the beats change. The MA-2 includes a newly developed speaker that delivers more power, allowing it to stand out against loud instruments and high frequencies.
The tempo can be set in three ways: in pendulum steps, like a mechanical metronome, in single steps, and using the Tap Tempo method by simply pressing a button at the desired tempo. Additionally, the time signature can be adjusted very flexibly - choose between 0-9 beats and one of eight rhythm types. This allows even complex passages to be practiced cleanly.
