09.Sideral

A memory that drifts like the sky: prime-length delays that never repeat.

Sideral is a sound memory of undisclosed length, carved into delay lines whose lengths are all different prime numbers of samples. Once their heads pass each other they never line up again, so your phrases keep recombining and nothing comes back as a loop. Slow chaotic tides carry the lines across the stereo field.

Twenty-one programs in five constellations read the same memory in different ways: two and four drifting delays, a reverberation the size of a county, clouds of grains, and nine Pulsar loopers locked to your host's bars that slice, shuffle, stutter and transpose the loop in place. A round REC button sits at the heart of the performance pads, which freeze the memory (Eclipse), reverse it (Retrograde), halve its speed (Redshift) or collapse it (Big Crunch). The editor is an orrery: every delay line is an orbit, every write head a planet.

“It never plays the same thing twice. We asked it to. It declined.”
