Store description excerpt
Guidetone turns any recording into your personal practice room. A guide tone is the 3rd or the 7th of a chord — the note that tells you where the harmony is going, and the one worth hearing first. That is the whole idea: show you what actually matters in a song, so the practice can start. Import a track, loop the hard parts, slow them down without changing the pitch, pull the band apart, and see the changes written out — all on your iPhone or iPad, and all without an internet connection. IMPORT MUSIC YOU OWN Bring in tracks from Files, iCloud Drive, or AirDrop — MP3, M4A, WAV, AIFF, FLAC. Guidetone renders a clean waveform so you can see the music while you work. (Streaming subscription downloads are copy-protected and cannot be imported by any app.) LOOP & SLOW DOWN Set A/B markers and loop any passage seamlessly. Change tempo and pitch independently — slow a fast lick to half speed without the chipmunk effect, or transpose to a friendlier key — with studio-grade, artifact-free time-stretching. Save your favorite loops, and use the Speed Trainer to ramp tempo up rep by rep. ISOLATE THE PARTS (ON-DEVICE) Separate a song into stems — 2, 4, or 6 parts — right on your iPhone or iPad. Mute the vocals to create your own karaoke or backing track, mute the melody and take the solo yourself, or solo the drums to lock in your time. Nothing is uploaded; separation runs entirely on your iPhone or iPad. SEE THE CHORDS Guidetone listens to the song and writes out its chords, laid out bar by bar on a Chord Ribbon that follows along as it plays. Choose a Pop or Jazz vocabulary. Wrong chord? Correct the label, set its exact spelling, or retime it by hand — your edit sticks. READ THE WORDS Guidetone can listen to a song and write down what is sung, right on your iPhone or iPad, with every word lined up to the audio. Read them as a chord sheet with the changes above the line, or open the Prompter and read from a music stand across the room: each word lights as it is sung, the page turns itself a phrase at a time, and you pick the reading size for where you actually stand. Chords sit in time on a bar you can touch — tap to scrub, drag to loop, and fix a chord where you see it. Mishear a word? Correct it right in the sheet. READ IT ON THE STAFF Open the Notation Editor to read the chords on a properly engraved lead sheet that follows the playhead, re-engraves when you transpose, and takes your edits right on the page. Engraved or handwritten-jazz notation, your choice. KNOW THE SHAPES Every chord in the song, drawn for guitar and for piano — and they sound when you touch them. Switch benches to see the same chord either way, with the positions and inversions laid out beneath it. RECORD YOUR TAKES Play along and capture it with a built-in count-in and a two-bus console: control exactly what goes into the recording and what you hear in your headphones, independently. EDIT LIKE A PRO A live, non-destructive audio editor: cut, copy, paste, fade, adjust gain,
