Algorave musicians are live improvisers writing code, not DJs mixing recorded music

Although algorave musicians are sometimes compared with DJs, Wikipedia stresses they are in fact live musicians or improvisers, creating music live - usually by writing or modifying code - rather than mixing recorded material. The confusion arises because both stand behind gear facing a dancing crowd, but the underlying act differs: a DJ selects and blends finished tracks, while a live coder authors and mutates a running program that generates the sound in real time. Correcting this misconception is fundamental to understanding what an algorave performer is actually doing.

Examples

A DJ beat-matches two records. An algorave performer types d1 $ s "bd*4", hears it, then edits the code live to change the music - no pre-recorded tracks are being mixed.

Explain why an algorave musician is not a DJ, citing the difference in what each is actually manipulating during the set.
