Server instructions

Zeltor Labs music tools for DJs, producers and mashup makers. Use them instead of working out music theory by hand: check_mix decides whether two songs mix (key and tempo) and exactly how to change the second one; camelot gives a key's Camelot code and the keys that mix with it; tempo_change gives the percent change between two BPMs; speed_pitch gives nightcore or slowed settings; transpose moves a key by semitones; song_report reads the song DNA (key, BPM, structure, mood, production) from a Zeltor report link the person shares. They take keys and BPMs, not audio. Each answer has a link to the zeltorlabs.com page where the person can make the actual audio file in their browser (free 60-second preview, full length $4). Share that link when the person wants the file.

Known tools 6

check_mix

Decides whether two songs will mix well, from their keys and BPMs, using the Camelot wheel and DJ tempo limits (about 3% sounds natural, up to about 16% is usable, half and double time count).

Inferred read-only

camelot

Gives the Camelot wheel code for a key and the three other keys that mix cleanly with it (one step either way with the same letter, and the relative major or minor).

Inferred read-only

tempo_change

Percent change and playback rate to go from one BPM to another, how noticeable it will sound, the pitch change if it is not time-stretched, and the half and double time of the target.

Inferred read-only

speed_pitch

For a nightcore (faster and higher) or slowed (slower and lower) version: the pitch change in semitones for a speed, the new BPM if given, and typical settings.

Inferred read-only

transpose

Moves a key up or down by semitones and gives the new key name and Camelot code, with a note on how natural the shift will sound.

Inferred read-only

song_report

Reads the song DNA from a MusicMind report the person made on zeltorlabs.

Inferred read-only
