Go Button vs LivePlay

Go Button is an iOS app for creating and running sound cue playlists for live performances on iPad, iPhone, and iPod touch. It can play several sounds at once, advance through a cue list with the GO button, or trigger ad-lib effects from Hit buttons. Cues may auto-stop, fade, loop, or duck, with separate volume, pan, speed, and pitch controls. Playback accepts iOS-compatible remotes, Bluetooth keyboards and accessories, MIDI input, OSC commands, and hotkeys. Shows can move through AirDrop or the iOS Files app, arrive from iCloud Drive or Dropbox, and be imported into QLab. Supported audio includes WAV, AIFF, AIFC, M4A, AAC, MP3, MOV, CAF, 3GP, MPEG4 audio, and FLAC; copy-protected files are excluded. It requires iOS 15 or later. The free version costs nothing for one saved playlist; the $99.99, paid once Pro License allows unlimited playlists.

LivePlay is a free desktop audio playback app for live shows, designed for live sound operators managing cues. Playlists and cart buttons support cue groups, fades, loops, crossfades, and next-cue actions. Cues can route to channels on one or more audio interfaces. Mixing and monitoring tools include audio buses, EQ, gate, compressor, auxiliary sends, output meters, loudness targets, and a master limiter. Playback control works through mouse, touch, keyboard, MIDI, HTTP, and WebSocket. Media can be added by drag-and-drop or YouTube audio import, with waveform display and LTC timecode output. A desktop controller can connect to a local or remote audio server over a network. LivePlay runs on Linux, macOS, and Windows and is released under AGPL-3.0-only. The Free plan costs nothing with all features and no licence fees, subscriptions, or paywalls. Remote control uses plain HTTP and WebSocket; installers are unsigned and macOS builds are not notarized.
