Built for the euphoric end of dance music

Trance Tools is a set of small, free utilities for producers chasing the uplifting, supersaw-driven sound of trance. Each tool answers one question you'd otherwise stop and look up: which chords lift, what delay time sits at 138 BPM, what pitch your kick should be in A minor.

Everything runs in your browser. Nothing to install, nothing to sign up for, and every tool that makes notes exports standard MIDI files for Ableton Live, FL Studio, Logic Pro, Cubase or Bitwig.
