MusicChina26: AmeNote-Azoteq Key Position Sensing

We had a chat with Mike from AmeNote-Azoteq who showed us key sensor technology developed with Azoteq for musical keyboards. We last heard about the system at NAMM, and the work now centres on bringing the sensing platform into instruments from keyboard manufacturers.

The system replaces traditional velocity switches with sensors that track the key through its full travel. It generates continuous position data, with 8-bit positional resolution and high-speed timing for higher-resolution velocity. The same sensor also supports polyphonic aftertouch. For piano actions, velocity can be measured in multiple zones, and sensors can sit under the key, on the hammer, or in both positions.

The sensing method uses a wedge of metal moving through a coil or antenna on a PCB, allowing the system to track position and speed without touching the key mechanism. The feel remains dependent on the keyboard manufacturer. Demonstrations included wavetable position scanning, aftertouch control, Hammond-style harmonic triggering, and capacitive UI components with haptics, LEDs, multi-touch and ribbon-controller-style gestures.

First keyboards using the technology are expected in 2027, with more planned for 2028.
