About Metro X: Tuner & Metronome
One app for every musician: a precise tuner, a metronome that counts out loud, piano accompaniment to play along with, and your sheet music, with the tools floating right on the score. Play in sync with anyone, on any phone, tablet or watch. In 15 languages. PLAY ALONG - Practice with piano accompaniment for voice, violin and more, from public-domain scores - Three playing styles: Steady, Practice and Expressive - Slow it down to 75 or 90%, or push to 110% - Loop any bars by dragging the edges of the piece, then repeat with a rest in between - Tempo ladder: each repeat steps the tempo up until you reach 100% - Slow a hard passage down inside the loop, with an easy step back up to tempo - Metronome click on or off, count-in, piano volume - Save your setups as presets; they follow your account to every device - New pieces arrive in the app as they are added - Bring your own: practise with your recordings (MP3, M4A, WAV), MIDI or MusicXML files TUNE - Accurate from the lowest bass string to the top of the piano, shown to 0.1 cent - Strings in pure fifths, the way string players tune by ear - Tune against a drone with fifth and octave, in three sounds - Violin, viola, cello, double bass, guitar, bass, ukulele, mandolin, banjo, harp, piano, voice, and transposing winds and brass - Alternate tunings and capo, automatic string detection, or lock a string - Concert A from 410 to 480 Hz - Temperaments: equal, just, Pythagorean, meantone, Werckmeister III, Vallotti and Kirnberger III - Five views: the new String, Halo, Arc, Line or Strobe, plus a pitch trace of the last 8 seconds - Display as Bb, Eb or F for transposing instruments, an in-tune zone and a gentle haptic tick KEEP TIME - Subdivisions, an accented downbeat and meters from 2 to 12 - Tap tempo and a big, clear beat you can see - Counts & Kits: seven voices — men, women and a kid — count out loud right on the beat, "1. 2. 3. 4.", in 14 languages, with "and" on off-beats and 5-6-7-8 count-ins for dance class - The ORB: a floating metronome on top of your score that pulses with every beat - Bluetooth delay calibration so the click lands on time in wireless headphones - Sync rooms: everyone in the room hears the same beat, on iPhone, iPad, Apple Watch and the web together. Hosting a room is free. Patent pending. READ - Your PDF library with Recent, Starred, setlists, tags and search - Scan paper music with the camera, cleaned up for sheet music; edit, reorder and rotate pages - A 30-day Trash, and share scores with or without your markings - Free public-domain scores from IMSLP - Annotate with Apple Pencil, a stylus or your finger: pen, highlighter and string stamps, in layers - Tap the edge of the page to turn, or use a Bluetooth page-turner pedal - Your scores sync to your Metro X account and open on all your devices - Bring your library over from another sheet music app APPLE WATCH - A standalone watch app: metronome with taps and clicks, the String tuner, Play and Sync rooms, even without your iPhone nearby ONE ACCOUNT Sign in with Apple, Google or an email code.
