Robo-SelectaAn endless set that writes its own tracks as it plays them

Every track is written on the spot from a genre's rules: its drums, its bass, its chords and a key on the Camelot wheel. Tracks are built in 32-bar chunks so they line up with how people dance: an intro, a breakdown and build, a drop and a switch-up, then an outro. One breakdown-to-drop cycle takes about 90 to 120 seconds (the Cycle fader).

The next key is always a harmonic mix: the same key, one step round the wheel, or the relative major or minor. When the tempos are close, the next track blends in over 32 bars with a bass swap halfway. When they are far apart, the old track winds up, echoes out and the new one drops on the 1.

Melodies play as call and response between two opposite ideas, named on screen while they play: low against high, straight against triplet, harmony against dissonance, nostalgia against now, and more.
