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.

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.
