Is zeltor-music-tools live?

Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.

Is zeltor-music-tools free to use?

Yes — the hub reached it with no key and no payment.

What tools does zeltor-music-tools have?

6 tools: tempo_change, transpose, song_report, camelot, check_mix, speed_pitch.

Is zeltor-music-tools safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• speed_pitch open 1h ago

  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. Defaults: nightcore 1.25x, slowed 0.80x.

• tempo_change unknown never probed

  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.

• transpose unknown never probed

  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.

• song_report unknown never probed

  Reads the song DNA from a MusicMind report the person made on zeltorlabs.com and shared: key and Camelot code with the keys that mix with it, BPM, genre mix, section structure with energy, and production DNA (energy profile, mood, arrangement density, compression, biggest moments). Takes the share link (https://zeltorlabs.com/report/r/<code>) or its code. Use the key and BPM with check_mix to compare it with another song. If the person has no report yet, they can make one free at https://zeltorlabs.com/analyze (the audio is analyzed in their browser).

• camelot unknown 1h ago

  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).

• check_mix unknown 1h ago

  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). Returns a verdict, the tempo change in percent and the target BPM for track B, the smallest key shift in semitones if the keys clash, and a link to make the matched audio.
