Tetragrid: Magnetic gate and CV pattern generator from the Manifold Reseach Centre
Tetragrid is a strange 2D cross-section of a polytope that generates voltage via placing pins on a magnetised board to connect cross-modulating touchpoints.
Tetragrid
It was released at the end of last year but has only just come to our attention. Tetragrid aims to generate patterns of CV and Gate through the manipulation of 30 cross-modulating touchpoints. These points are connected to 6 LFOs that emerge at the top of the module. The middle 4 are free running, the two outside ones have knobs for rate control.
With nothing connected you get 6 regular triangle-shaped LFOs running from around 0 – 1ov although the Manifold Research Centre is not entirely sure. The LFOs are transistor-based and can be a bit unstable which comes into its own as you start to fiddle with them. As you start to place the pins or make connections with your fingers the behaviour of the outputs changes and can give moments of scatter and nonsense as it tried to find a new normal.
Tetragrid is not really about control, it’s about discovering new avenues of interaction and playing within the boundaries of the game to generate a filthy layer of randomness.
