eTextile-Synthesizers are handcrafted multi-touch digital interfaces based on smart textile materials and custom electronic solutions. The project features a fully embedded multitouch controller that combines the powerful Teensy 4.0 MCU with the E256 eTextile matrix sensor — a 16×16 FSR array with hardware interpolation up to 64×64 points.
The interface is configured via a browser-based mapping application that communicates with the device over USB-MIDI. Mappings (touchpad, slider, switch, knob, grid…) are defined visually, saved as JSON, and uploaded to the device.
