At the 2015 NAMM Show, Starr Labs was previewing their AirPower 3 wireless MIDI interface.
The AirPower3 works with all class compliant USB MIDI devices, such as the Novation Launchpad, Ableton Push, Alesis Keyboards and hundreds of other instruments and devices.
It features include 16 selectable RF channels, dropout protection to prevent stuck notes and up to 200? of unobstructed range.
They stopped by the Roger Linn booth and Linn gave it a spin with the LinnStrument:
Viia Geert Bevin, who notes, “StarrLabs came by the LinnStrument booth with a prototype of their upcoming AirPower3. Wireless class compliant MIDI over USB with 36 hours of bus power built in. The latency is barely noticeable, I could only slightly feel it when playing rapid 64th notes. With that we instantly have a perfect wireless solution for using the LinnStrument on any stage..
