SingZ — Sing With The Band

SingZ turns a song you already own into a rehearsal room. Instead of one flat recording, a SingZ song is six separate tracks — lead vocal, backing vocals, drums, bass, guitar and piano. Mute the lead vocal and the band plays on without you. Keep it in and sing along. Drop the drums to hear whether you are actually holding time. It is your song, taken apart, with every part on its own fader. HOW SONGS GET HERE Add one right on the phone. Pick an audio file from Files — your own recording, something you bought, anything on the device — and SingZ takes it apart into six tracks here, on the iPhone, with no server and nothing uploaded anywhere. The first song you add downloads the separation model (about 136 MB, once), and splitting needs a reasonably recent iPhone with enough memory; if yours cannot manage it, SingZ says so rather than trying. You can also prepare songs on a computer with the free, open-source SingZ desktop app for Mac and Windows and read them here — over Google Drive, or from a folder you copy across. Either way the result is the same six tracks. If you have not added anything yet, the app ships with one complete song so you can try everything straight away. WHAT YOU CAN DO WHILE SINGING • Six faders, one per instrument. Silence what you want to replace. • Lyrics that light up word by word as the song plays — tap any line to jump there. • Transpose to a key that suits your voice, without the song turning to chipmunk. • Slow a passage down without changing its pitch, until your mouth catches up. • Loop the eight bars you keep fumbling, with a count-in that lights each click. • Lock the phone and keep going. The song plays on, and the Lock Screen and Control Center have play, pause, a scrub bar and ten-second skips — so the phone can sit in your pocket or on the music stand. Songs open in a moment: the tracks stream from their files as they play instead of the whole song being loaded into memory first. TRAIN YOUR EAR AND YOUR VOICE The Train tab plays you a note and listens: single notes, intervals, notes in a chord, carrying a line — in a key you pick, or the key of the song you just had open. It waits until you hold the note in tune for a moment before moving on. Not in the mood to sing? Switch to Identify and name what you heard instead. The microphone is only for listening; nothing is recorded or stored. PRACTICE THAT PUSHES BACK Training mode drops the tracks you lean on, on a schedule — every few bars, or at the start of each lyric line. The backing vocal disappears and you find out whether you knew the harmony or were following it. Turn it up as you improve. LYRICS YOU CAN PUT RIGHT When a word comes out wrong, fix it in the desktop app: type the real words, drag a word onto the exact moment it is sung, or let SingZ line the whole song up for you. The corrected lyrics reach the phone the next time it syncs. OFFLINE, AND YOURS Songs you open are kept on the phone, so the train, the car park and the green room all work with no signal. Google Drive sign-in is optional: SingZ asks only for access to files it created itself, never the rest of your Drive, and there is no SingZ account to make. No ads, no analytics, no tracking — the code is public if you would like to check. Bring your own music. SingZ has no catalogue and no store; it works on the recordings you already have.
