This box is comprised of selected modules for drone composition. IO Instruments Himalia Chords/Drones section is one of the oscillators. Mutable Instruments Braids is the other. Braids is passed through Xaoc Belgrad filter. The two signals are mixed and processed by the Tiptop Audio ECHOZ effect Tape Delay Chorus. Four random LFOs are applied to various parameters. Then I tweaked it in real time.
The recordings seem noisy because the Himalia Chords/Drones is made up of six square waves.
