Two ways your music gets made

The synth composes for free in a few seconds; the AI writes whole songs with vocals. You drive both from the same studio.

Free on every plan

The synth

0 credits · a track is ready in seconds

  • Instrumental music and nature scenes from our own synthesis
  • Stems for every track, plus MIDI for the music
  • BPM and key written into the MP3 and the FLAC — Rekordbox, Serato and Traktor read them
  • The same seed always gives the same track
Paid in credits

AI songs (ACE-Step)

5 credits for every started 4 minutes

  • Whole songs with vocals, on your own lyrics
  • Genre, tempo and mood from your prompt
  • Commercial use on the Basic, Studio and Pro plans
nature — synthesiser plus an AI texture

14 kinds of nature. Not a single sample.

These 14 are procedural and cost 0 credits. The studio also has an AI texture engine (stable_audio) — that one costs 2 credits per clip.

All of it computed, none of it played back from a library — so there is no loop point and no two renders alike.

Credits work like Suno’s: one AI song of up to 4 minutes costs 5 credits. Everything from the synth is free.
