I have wanted a wind synthesizer (or Electric Wind Instrument - EWI) since I first saw one in Denver many years ago played by a member of the band Images. The instrument is very versatile, being able to sound like many different instruments. High prices and the complexity of the setup kept me away for years. One had to buy the instrument itself and a MIDI unit and it all seemed pretty complex. Once I saw the EWI USB priced as it is and that it is essentially a self-contained unit (one does need a computer, either Mac or Windows though) I was sold. It was an added bonus that Sweetwater carried it since I have had nothing but excellent service from Sweetwater on multiple purchases. I'm still learning the instrument but it is great fun to play. It is capable of being set for different fingerings as well as a multitude of instrument sounds. As other reviewers mentioned, the owner's manual is not much, but there are resources on the Internet including different sounds and software. I don't know why manufacturers don't feel the need to make a good manual with their product, but it seems to be the norm now. This is a great product for the price and as far as I'm concerned, you can't beat Sweetwater's service. I also bought a Samson computer stand to hold my MacBook Pro and I love it as well. By the way, the Garritan ARIA software included with the EWI USB works great on the Mac. As of the writing of this review, I have had the instrument for several weeks and am becoming more comfortable with it as time progresses. I played the clarinet and toyed with the saxophone and flute for quite a few years. The feel of the EWI is familiar, but different from a conventional instrument. The "keys" don't move, but are touch sensitive. The octave rollers replace the conventional thumb hole and key, so that is different, but pretty easy to pick up the feel. The instrument is fairly light weight, but you do need to use the enclosed neck strap since you need to keep your thumbs in certain places and it is a little tricky to just hold the instrument without the support of the neck strap. If you are a woodwind fan, I think you will get a kick out of this instrument. I'm running through a MacBook Pro via a USB port and out of the headphone jack and then to an Ampeg BA 108 amp that I already had. (I'm a bass player too.) I got the cables from Sweetwater as well. (3.5mm to 1/4 inch jacks on a 10 foot cable) The setup gives me plenty of sound. I'm very happy with my purchase and rig!
