"I am completely blown away by the K-Bow. As a controller and sound modulator, this bow is capable of doing a multitude of things, and it is all packaged in a very rugged and user friendly interface thus enabling the user to be infinitely creative. The bow itself has the feel and balance of a finer bow, and the emitter attaches below the finger board in a completely noninvasive fashion. One literally has the power to control and manipulate sound at their finger tips with virtually no disruption to the technical act of playing their instrument. It really is the coolest thing that I have ever seen."

"The most expressive modulation source in my rig is the K-Bow. Its seamless integration allows me to fluidly control effects, loops, and oscillators while I play the violin."

"For the composer and performer, the K-bow unlocks vast new creative possibilities. And it's all magic. The wireless electronic sensors and triggers are totally hidden and built in to this incredibly 'intelligent', beautifully and perfectly balanced and weighted bow. They are transparent to the user and the audience. String players love the fact that it feels right, it plays right and that there are no encumbrances. It's just a great bow!"

"As a cellist and computer musician, I have been thrilled with the K-Bow. I find it the most intuitive and responsive controller I have ever used. It allows me to employ all my years of classical music training to interface in a meaningful way with multiple software packages."

"In recent times, there has been an explosion of innovation in the world of digital sound, most of which has passed the violin bow by... until now. The capacity of the new K-Bow has to be heard to be believed. The personal and subtle characteristics of each bow and performer are measured by the latest in sensor technologies including a Force sensing resistor, Infra Red sensor and Antenna, and accelerometers. And the whole thing is wireless, utilizing an improved Bluetooth transmission system. A cooler bunch of relevant technology on a bow there is not. I've been involved with interactive bow experiments and prototypes since 1987, and this, let me tell you, this is it! Welcome string players to the 21st century."

"...the actual sounds are sent to the computer for processing. The software breaks the signal down into several sonic properties, but is claimed to retain the acoustic dynamics of the string behavior. The programs can be used to analyze or synthesize the sound, and output a performance as a format readable by scoring programs." more…

"I have an electric cello with RMC pickups, so you betcha I'm interested in this stuff. The K-Bow can generate MIDI or OSC data and send it wirelessly. I've seen attempts before to capture bow movements as MIDI or OSC data, but this is the most elegant solution I've seen yet - earlier attempts involved wires attached to the bow." more…
