Multitracker vs iDoctor Live Stems

Multitracker is a live player that allows you to play multiple audio files and midi files comfortably and flexibly with the help of playlists. If a USB audio interface is connected to the iPad, the audio tracks (stems) of a song can be routed to any of the outputs of the interface. At the same time, the headphone output can also be used as an additional routing destination, so that you have two additional channels available. To play midi songs, Multitracker provides a midi player that allows each MIDI track to be assigned to any existing Midi device (whether via USB or iPad instrument such as Sound Canvas). Of course a midi song can be played in sync with audio tracks. If necessary, a metronome with 9 different click sounds and freely selectable time signature can be added to your song or be played alone. It has never been easier to play multitrack and midi songs on stage!

iDoctor Live Stems turns your iPad or iPhone into a stage-ready multitrack player. Load up to 6 stems per song, hit PLAY and every track starts sample-locked. Each track has its own fader, mute, solo, pan, meter, waveform, color and an independent physical output to your USB-C multichannel interface: click and cues to the band's in-ears, the mix to the PA. BUILT FOR THE STAGE • Host-clock synchronized start: no drift between tracks, not even when seeking or looping. • Console-style mixer with long faders, live VU meters, protected gain and per-track lock. • Timeline with waveforms, draggable playhead, section markers (create, edit and jump with GO TO) and per-section track automation. • Seamless A-B loop/vamp to stretch a section until the band is ready. • Full-width on-screen lyrics with autoscroll, manual scroll and pinch zoom. • Real-time pitch ±12 semitones and tempo 50–150%, remembered per song. • Count-in, setlist auto-advance and chained medleys with crossfade. YOUR OWN RECORDED CUE TRACK • Add a recording track, arm the mic and record your spoken cues in sync with the song, watching the waveform draw live. • Record in one pass or in parts, with automatic latency compensation, take undo/redo and full editing in a full-screen audio editor: silence, crop, gain, fades, shift and export to WAV or M4A. • Route it only to the in-ears: the audience never hears it. • Built-in automatic latency calibration and precision test: your takes land exactly where you sang them. TRUE MULTICHANNEL ROUTING • Global or per-song output matrix: each track to its stereo pair or mono to a specific physical channel, with a test tone per output. • Works with class-compliant USB-C interfaces (iConnectivity, Zoom, Universal Audio…). Without an interface, it plays in stereo over the speaker or AirPods. YOUR LIBRARY, SAFE • Automatic file verification and repair: SHA-256 integrity and restore from iCloud when a local file goes missing. • Rotating ZIP backups (plus weekly automatic), visible in the Files app. • Automatic sample-rate conversion on import, drag & drop from Files or Finder, and stereo mix export to WAV. GIG-READY • Setlists with their own order, notes, per-setlist chained medleys and one-tap start. • Preflight: checks stems, integrity, channels, battery and temperature before you go on. • Concert mode (screen stays on), resume after a crash, persistent show log and interruption handling. • MIDI pedalboard (Bluetooth or USB): play, stop, sections, vamp and panic with your foot. • Remote control from a second iPad/iPhone, Apple Watch support and a backup iPad with hot takeover. • Optional iCloud sync (complete songs, audio included) and backup to your own cloud via Files. AirDrop complete songs between devices. • Built-in manual, available in English, Spanish, German and French. • Also on your Apple Silicon Mac (Designed for iPad), with drag & drop from Finder. iDoctor Live Stems is a musical performance tool, part of the iDoctor Music Tools ecosystem.
