When I patched random voltages into the Quadrax, the built-in attenuator on its first channel was a little bit to strong. That's why notes aren't very random in the first clip with the quantizer. I corrected it in the next cut but it was to messy to describe everything in the voiceover. Just putting it here as I'm sure someone will ask about it. It's eurorack things :)

Apart from the Quadrax, the other tracks in the project were done using:

Bass - Retro Synth
Cello - Felt Instruments Blisko
Effects + pad sweep: Pigments and u-He Diva
Chords + melody: OB-6
