Body only. Operation confirmed. ◆ The M-One XL is designed for musicians seeking quality and live sound engineers, and following TC's tradition, the M-One XL offers the best quality in its class. ◆ The XL reverb technology, the heart of the M-One XL, is the latest spatial simulation technology realized through TC's long years of research and development in the field of reverb. The M-One XL reverb allows for more detailed adjustment of the reverberation components in all reverb algorithms. Furthermore, the "Reverb Size" setting range has been expanded, allowing you to define from narrow spaces to extremely wide sound images, independently of the decay time. With the M-One XL, the reverb size setting is reflected in both the initial reflections and the decaying components, allowing for extremely flexible settings such as a wide space with a short decay time, or a narrow room with a long decay time. ◆ The M-One XL reverb is composed of a combination of high-resolution initial reflections and decaying sounds, achieving a natural and clear sound that is unprecedented in this price range. The M-One XL reverb technology also allows for the modulation of the decaying sound. From the extremely small amount of modulation caused by the movement of air in real spaces, to vintage-style modulation, and effects-like settings close to chorus and detune, you can obtain dynamic decaying sounds that are impossible with mere simulation.
