A unique device for sound experiments. Its real strength is in modulation and its sound engines, as well as the flexibility of its settings. A big plus is that it works as an audio interface, so you can record everything track by track into a DAW, or send audio from the DAW into it for processing. It’s fully self-contained: you can make a full track using its four tracks.
On the downside, this is my second unit — I returned the first one because it constantly clicked and had lots of glitch noise. This one has almost no noise or glitches, but occasional odd behavior still happens. Despite that, I really love it for its looks, interface design, and overall capabilities.
