OverDrive Chords & Stems

Vocal remover, slow loops

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Import a song: chords detected, stems split, any phrase looped at half speed, all on device, nothing uploaded. With a band, everyone shares one chart and one playhead. Turn any song into something you can play along to: chords detected for you, four stems split out, any phrase looped at half speed without changing pitch. All of it runs on your iPhone. No audio is ever uploaded. That's on your own. With a band, everyone shares one chart and one playhead. ■ Chord detection, stems and phrase looping Import a song and get its chart in about ten seconds, right on the device; split it into drums, bass, other and vocals whenever you need to, then loop one phrase as long as you like: 0.5x-1.5x without changing pitch, solo or mute any stem. Paste in the lyrics and the phone listens to the song and puts each line on its bars (needs iOS 26). ■ Backing tracks for practising alone Drums, bass and guitar follow your chart. Nine styles (pop, rock, ballad, country, shuffle blues, reggae, funk, jazz swing, bossa nova), each with two alternate arrangements, and each part can be muted. The harmony comes from your chart: what you write is what you hear. ■ Video practice Import a lesson video from your phone, mark in and out, loop those few seconds full screen, slowed down if you like. ■ Number-system charts No staves, no tabs, just the numbers (1 5 6 4). Change the key and every chord on every screen follows. ■ The chart moves by itself, so your hands stay on the instrument Hit play and the chart advances at the song's BPM: which beat you're on, what this bar is, what comes next. Section changes come with a countdown. ■ Songs are written in sections Intro, verse, chorus, bridge. Each section carries its own progression and repeat count: you are in the chorus, it goes 1 5 4 6, pass 2 of 3. Singers can switch to the lyrics view and get prompted line by line. A full chart can also live on your Home Screen: pick a song in Settings and add the widget. ■ On iPad, it's the music stand The rehearsal view lays out the whole song like paper: one panel per section, four bars to a row, lit up to wherever the band is. Put it on a stand and play. ■ Local network sync, no internet needed One person hosts, everyone else types a four-digit room code. The leader starts, changes tempo, jumps sections, locks a loop, and every playhead moves together. No server, no account, no sign-in. ■ Rehearsal recording Plug in your mixer or audio interface and record the whole session. Every time someone hits play it becomes a take; keep the ones worth keeping and export m4a. ■ Full-song overview and PDF export What you see is what you print: the same chart, the same page. ■ Subscription OverDrive Pro is an auto-renewable subscription, 1 month. The price for your storefront is shown in the App Store, and in the app, before you confirm. It unlocks the AI transcriber, hosting a room and PDF export. Everything else is free with no time limit, including on-device stem separation, looping, video practice, and joining someone else's room, and for the first 30 days after install those three are free as well. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel it in Settings > Apple Account > Subscriptions. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://overdrive.work/privacy — The interface is available in English and Simplified Chinese. OverDrive collects nothing: everything stays on your device and works entirely offline.

  • This app hasn’t received enough ratings or reviews to display an overview.

Two new things this time, plus a pass over every button in the app. ■ Home chart Pick a song in Settings and a full chart shows up on your Home Screen: one panel per section, four bars to a row, in one of three styles (signage, panel, bare). Long-press the Home Screen, tap +, and look for OverDrive Chart. The last-rehearsal widget was clipped on both sides at its smallest size; fixed. ■ Lyrics Once a song has been transcribed, the practice page gets a Lyrics button: paste the words, the phone listens to the song and places each line on its bars, and you check the result before adding it to the chart. Lines it couldn't make out are greyed so you know which ones to look at. Recognition runs on the device and needs iOS 26; the first run downloads a model. ■ Buttons Every button was gone over: full-width actions, small option chips, the cancel/confirm pair at the bottom of sheets, tappable list rows. Sizes and selected states now match across the app. The host and join screens have a proper top bar. ■ Also The white scroll bar on the right edge of the dark interface is gone.
