AKAI PROFESSIONAL EWI5000WhiteJ ELECTRONIC WIND INSTRUMENT Functionality confirmed. ↓ Quoted from AKAI Pro HP ↓ Similar to previous models, the special sensor that responds to the strength of the player's bite on the mouthpiece and the strength of the breath allows for subtle control of pitch, timbre, and volume. Furthermore, equipped with eight parameter knobs: Filter, Breath, Bite, Semi, Fine, Reverb, Chorus, and LFO, each allowing for fine-tuning, conveying the player's expressiveness without reservation. ↑ End Quote ↑ Pitch bend (Up, Down) and glide bar function without issue. Output terminals (headphones, audio out) output without issue. Like new, functionality confirmed, but please understand that this is a used item. If you are looking for a perfect item, we recommend purchasing one with a warranty from a musical instrument store or the manufacturer. The mouthpiece has been disinfected with alcohol.
