4ms Tapographic Delay

The Tapographic Delay, designed by Matthias Puech and 4ms Company, is a complex multi-tap delay in the Eurorack format with a unique interface designed for live performance. It excels at transforming the simplest audio (a drone, a percussive sound) into complex rhythmic structures, meshes of organic textures, lush harmonic mille-feuilles, liquid and resonant effects.

The Tapographic Delay is an expressive experimental instrument meant to be played in real-time, rather than a set-and-forget end-of-chain effect. Interact with it! Experiment! Push it to its limits!
