Didn't saw the reply ...
OK, just a few more explanation: the SYLPHYO is not intended to compete with Akai EWI or Yamaha WX.
It is indeed a wind controller but it is much different:
- your breath can get through the instrument similarly as what you know with acoustic instrument (which is not really the case with EWI and WX as the internal tube is rather small), so the feeling is much closer to playing an acoustic instrument: this is probably the main point as we had to design a specific patented technology to achieve this
- it is much more compact and lightweight (nearly half the size and weight of the two others)
- wireless MIDI ... (adding such an interface to an EWI or WX cost at least 100 $ and it is not possible for the EWI USB you mentioned at 299$)
- expandable (internal slot for synthesizer board, active alternate mouthpieces that we have under development ...)
- as easy to play as playing a flute recorder
- internal motion sensor to add extra expression control or alternate not breathing control modes ...
I would describe the Sylphyo as a little brother of the EWI and WX, with unique features making it an instrument of its own.
Hope this answer some of your questions.
