CueStack

Mark cue points on any audio track, then replay sections on demand to time your show. Generate or read SMPTE/LTC timecode and run cues over OSC and MIDI, all on iPad.

CueStack marks cue points on an audio track and replays any section on demand, so you can time lighting, video, and effects to the music. Set your points once, then tap any of them to jump there and replay that section live.

Built for live-event operators, video programmers, theatre and AV techs, and worship teams.

MARK & REPLAY • Place cue points on the waveform and give each one a type • Use the built-in types (Audio, Video, Lighting, Pyro, SFX) or create your own with a name, color, and shape • Tap a cue to jump to it and replay that section • Drag a cue along the waveform to adjust its timing • Pinch to zoom for precise placement
