This is the Emeo digital saxophone. The color is the new model, Black Nickel. It produces sound via USB or Bluetooth through a PC. The manual is also included, so please check the official Emeo website for details. https://www.emeomusic.com Because it produces sound through a PC, it's perfect for fingering practice. You can change the fingering to E♭, C, and B♭, allowing you to practice soprano, tenor, alto, and C instruments. You can perform tonguing. The volume can be changed by the strength of your breath. MIDI software is not included. This was a gift, and I have no knowledge of it. One part is damaged and needs repair. I am selling this as a junk item, only tested for power. Please check the condition in the photos.
