Aerophone Roland Aerophone AE-05, a model capable of reproducing various tones. - Brand: Roland - Model Name: Aerophone AE-05 I purchased this around June of last year for fingering practice and used it for about six months. The mouthpiece is new (I don't plan to include the one I was using). Currently, there are no operational issues. I handled it with care, but there may be some scratches as shown in the third photo. Please consider this if you are not concerned about minor imperfections. Since it has volume control and headphone connectivity, it's a digital wind instrument that allows you to practice fingering even in places or at times where you can't play a regular instrument. The "Aerophone Editor" app allows you to customize sound creation and performance settings on your smartphone. You can also play along with your favorite songs in an ensemble. The included Aerophone GO operation guide & score have some wrinkles. The CD has been opened but is in good condition. 《The items in the photos are all that are included. Please understand.》 If you have any questions, I will answer them to the best of my ability, so feel free to message me. (Replies may be delayed.) 〇About Shipping I have disposed of the product box, so I will ship it with cushioning material. ■ Aerophone ■ Digital Wind Instrument ■ Wind Synthesizer ■ Sound Quality: PCM sound source ■ Tones: Preset 11 (50 more tones available via the app) 4 types of saxophone, flute, clarinet, muted trumpet, violin, synth sounds, and even percussion ■ Operation Keys: Based on saxophone ■ With F# key ■ Sensors: Breath sensor, bite sensor ■ Octave Shift: ±1 ■ Thumb Controller: Button type ■ Bluetooth equipped: MIDI / Audio ■ Power: USB powered ■ Dimensions: Length 454mm, Width 128mm, Thickness 78mm ■ Includes a carrying case #digitalsax #saxophone Thank you for viewing.
