Mapler

Eurorack Video Mapping Instrument

Real-time video mapping instrument for live visual performance.

Mapler is a Eurorack video mapping instrument designed to turn video into a playable medium.

Power it directly from the front-panel USB-C connector or from the Eurorack power bus, selectable via an internal jumper.

It processes external video sources, including live video input, and lets you select, shape, and map visuals in real time.
Control your visuals using the built-in joystick for fast, organic gestures, or connect a USB mouse for precise editing.

Built around a 4-layer workflow — Atelier, Output, Master, and Play — Mapler gives you full control from composition to performance.

Save and recall compositions from USB, and sequence them using the internal sequencer and TRIG input (random, ping-pong, and more).

Play Mode transforms your mapped visuals into a playable instrument, with real-time movement, rotation, and optional inertia.

Designed as the perfect companion to the Video Slooper.
