Your rehearsal / audition / performance on cue

Replayer is a free, cue-based media player for rehearsals with playback music.
By the click of a button, Replayer starts to play at predefined times in the audio or video file.

How it works

  1. Add music files (mp3, wav, ...) to create a compilation of tracks.
  2. Add cues to specific points in time (e.g. intro, verse, chorus,...) in the playback file, with a name and an optional shortcut mnemonic
  3. In the session, using Replayer on your portable device, play any part of your set with the click of a cue button.
  4. Additionally, you can use a (bluetooth) numeric keypad, as a remote control
