Analog interface drift. I was told that with each analog/manual interface, a small amount of drift or irregularity is introduced. This is a favorable outcome that heightens the appreciation of the music experience.
After a few hours the robot emerged from the slot canyon and stepped into the waning sunlight. They stopped and removed the map and added some updates. They surveyed the scene stretching out ahead: the canyon had connected the known with the unknown.

Making my way through a narrow alley I happened upon these two having what appeared to be some sort of dance party? A dance off? A comparison of rhythmic movements timed to changes in audio frequency? I asked why they would play the music out loud via a speaker and not just import the waveforms directly. The robot holding the speaker reached out and placed it against my chest; I felt the vibrations and thumping of the music. The robot withdrew the speaker and both continued their movements.
