BU16 Series 3 is a compact and expressive button module designed for dynamic control in creative environments. It features a 4x4 grid of MX Gateron Hall effect switches, offering velocity and pressure sensitivity for responsive, nuanced input — ideal for triggering samples, launching clips, controlling playback, or finger drumming with more depth.

Each button is backed by an RGB LED, and the default keycaps feature cutouts, ensuring that the LED indicators remain clearly visible during use. The keycaps are interchangeable, making it easy to customize layout, feel, or labeling to fit your workflow.

The fiberglass front panel now has a textured finish, giving the module a solid, durable feel with improved grip for everyday use.

BU16 buttons can be configured for momentary, two-step, or three-step toggles, encouraging playful experimentation in both performance and production setups. Fully compatible with other Grid modules, BU16 can be used as a MIDI controller or HID macro pad, depending on your needs.

All LEDs are configurable via the Grid Editor — adjust individual brightness, assign custom colors, or add pulsing animations to clearly differentiate controls, especially in low-light setups.

Use cases include:

• Triggering samples or one-shots in a DAW or standalone sampler

• Launching clips and scenes in software like Ableton Live

• Controlling transport functions (play, stop, record, etc.)

• Finger drumming or live pad performance

• Switching tools or layers in visual/VJ software

• Sending macros or shortcuts as a HID controller for creative applications beyond music (e.g., video editing, graphic design)

In-depth configurability

The Grid Editor enables a highly-customizable controlling solution through in-depth programmability in LUA code.
