Expressive Digital Woodwinds: The Akai EWI USB controller winds
Bring the organic nuance, breath control, and expressive articulation of traditional woodwind and brass playing into the digital world with the Akai Professional EWI USB. Purpose-built as a high-fidelity electronic wind instrument, this streamlined MIDI controller gives wind players a direct bridge to contemporary music production software. By converting raw breath velocity and lip pressure into high-resolution multi-channel MIDI data, the EWI USB breaks down the boundaries of linear keyboard tracking. Wrapped in a lightweight, sleek ergonomic chassis that mimics a traditional soprano sax or clarinet layout, it scales down your production footprint into a highly mobile instrument. It is the perfect studio tool and performance asset for traditional horn sections, woodwind students, and experimental electronic musicians.
The expressive power of the EWI USB resides inside its highly sensitive, specialized mouthpiece module. Driven by an advanced internal air-pressure level sensor and a reactive mechanical bite sensor, the instrument interprets the precise velocity of your wind stream to dictate note volume, filter dynamics, and expression mapping, while your lip squeeze translates to fluid pitch-bends and wide vibratos. Below the mouthpiece rests a layout of 13 touch-sensitive metallic keys that respond instantly to finger capacitance, eliminating the mechanical clatter and key-sticking of acoustic pads. Operating on an efficient, class-compliant USB data pipeline, the instrument draws full system power and pipes low-latency performance commands over a single cable directly into your computer workstation.
Smart Fingering Flexibility and Deep Performance Controls
Emulate your native acoustic instrument layout or navigate multiple octaves with tactile ease:
Multi-Instrument Fingering Modes: Configurable internal switching options that map the 13 touch keys to mirror Saxophone, Flute, Oboe, Traditional EWI, or Brass/EVI (Electronic Valve Instrument) layouts.
Precision 4-Roller Octave Bank: Outfitted with 2 mobile and 2 fixed touch-sensitive roller wheels on the rear panel, enabling players to sweep flawlessly across a wide 5-octave musical range with a slide of the thumb.
Dual Dual-Plate Pitch Bend Switches: Integrates dedicated physical grounding and pitch-bend metal plates on the back to trigger immediate, manual semitone glides or natural expression dips.
Removable, Dishwasher-Safe Mouthpiece: Designed for clean longevity with a fully detachable protective plastic tip that can be quickly removed for sanitization between performance sets.
Integrated Anti-Slip Cable Holder: Features a structural mechanical chassis clip at the base of the instrument to lock the USB cable in place, preventing accidental stage disconnects.
Native Soft-Synth Integration and Specialized Aria Engine
Launch custom acoustic emulations and rich synthesizer soundscapes straight from your desktop:
Garritan Aria Sound Player Suite: Bundles custom standalone, VST, and AU software modules specifically voice-optimized to translate the EWI’s high-resolution wind control curves into stunning physical instrument models.
Expansive Multi-Genre Instrument Library: Features pristine digital sample models spanning classical orchestral brass, traditional jazz woodwinds, cinematic string sections, and vintage synth wave leads.
Universal Custom DAW Mapping: Functions as a standard class-compliant MIDI controller, enabling you to map your breath curve to control any external third-party virtual instrument or synth plugin.
🎷 Breath Mapping & Plugin Configuration Pro-Tip: By default, the EWI USB outputs breath pressure information via MIDI CC#2 (Breath Control) or MIDI CC#11 (Expression) rather than standard keyboard velocity. When mapping third-party synthesizer plugins (like Serum, Omnisphere, or Kontakt strings), you must manually enter the plugin’s modulation matrix and assign CC#2 to control the Main Volume, Filter Cutoff, or Wavetable Position. This creates a deeply realistic sound design where the volume and tonal brightness of your synthesizer track directly to how hard you blow into the instrument mouthpiece.

FAQS
Akai EWI USB controller winds Frequently Asked Questions
Does the EWI USB contain internal sounds or built-in audio speakers?
No. The EWI USB is a dedicated USB-MIDI control surface and does not contain an internal sound generation engine, headphone outputs, or built-in speakers. It functions exactly like a USB MIDI controller keyboard, processing your finger taps and breath speed into digital command notes. To generate sound, it must be linked via its USB cable to a computer or iPad running a compatible sound player plugin or DAW.
What are the primary differences between the EWI USB and the EWI Solo?
The EWI USB is an ultra-lightweight, streamlined model designed purely as a controller to drive computer soft-synths over an attached USB connection. The EWI Solo is an entirely self-contained instrument that is noticeably larger and heavier. The Solo features an internal sample-based sound engine with 200 onboard sounds, a built-in speaker, a built-in rechargeable lithium-ion battery, a larger 7-octave roller bank, and analog 1/4-inch line/headphone outputs.
Can I use this wind controller if I have never played an acoustic horn before?
Yes! Thanks to its highly customizable system software, the EWI USB is incredibly beginner-friendly. Because the touch keys require zero physical finger pressure to seal a tone hole, it is much easier to play cleanly than an acoustic saxophone or flute. Beginners can start on the highly intuitive “Traditional EWI” fingering mode, which utilizes a simple linear up-and-down scale progress layout.
