## What is OverDrive Chords & Stems?

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.

## Version history (last 5 releases)

### 1.3.2 — 2026-09-21

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.

### 1.3.1 — 2026-09-03

This one is about iPad, plus an import bug that had been sitting there all along.

■ Importing a video from Files works again
Only the Photos route used to work: videos you AirDropped or copied from a
computer were greyed out in the file picker. This had been broken since video
practice first shipped.

■ iPad landscape no longer collapses
The home screen was laid out again for landscape: the sign wall becomes a slim
eave, the four doors turn sideways, and the capsule at the bottom is neither
covered nor pressed against the cards.
The rehearsal transport bar now picks its scale from the width it actually has —
the three glass groups have gaps again, the metronome label is no longer clipped,
and the play button is square.
Charts, AI transcriber and video lists no longer put one card on each edge with a
hole in the middle.

■ Also
A few Chinese strings that leaked into the English hosting screen are fixed.

### 1.3.0 — 2026-08-30

This one is about rehearsing a song the way bands actually do — again, and again.

■ When the song ends, it starts over
No reaching for the phone. Every time it comes back to the top it counts you
back in, so you hear it begin again instead of watching the playhead jump.

■ Two things sound right again
Switch to another app and back: the backing track and metronome no longer go
silent. And the guitar has a new set of samples, so a slide between two notes
is a finger moving along the string, not two notes stitched together.

■ If this is your first time opening it
· One chart, one playhead for the whole room — read out a 4-digit code to join.
  No account, no internet.
· Chords in the lead sheet are coloured by scale degree, so the same degree is
  always the same colour — readable from a step back.
· Import a song: it splits into four stems and gets its chords transcribed
  entirely on your device. Loop any phrase, at any speed.
· A Live Activity on the Lock Screen and Dynamic Island, and a "continue last
  rehearsal" widget on the Home Screen.
· On iPad the rehearsal view is the whole song on a music stand: one panel per
  section, four bars per row.

### 1.2.0 — 2026-08-29

This one is about the work under your hands.

■ Trimming a passage is a viewfinder now
Picking a passage to loop — in practice, and in video practice — used to mean dragging two
handles out to the ends of the waveform.
Now the frame stays put on screen and the waveform slides underneath it. You push the
audio; whatever sits in the frame is your loop.
Both screens work the same way from here on.

■ A visual pass over four screens
Rehearsal, practice, charting, room setup. The same subtraction in each: what is happening
right now got brighter, and what wasn't saying anything got out of the way.
The rehearsal control bar in landscape lost 11 points of height, and the chart got all of it back.

■ The lead sheet on iPad
Chords are set a size larger and coloured by scale degree — the same degree is always the
same colour. On a music stand you can read the next chord from a step back.

■ Three playback fixes
Practice playback and rehearsal-take playback sometimes ran fast and sharp — they are back
at the original tempo and pitch.
Looping a whole song in stems no longer drops a short silence every dozen seconds.
After a call or an alarm interrupts you, hitting play picks up where the sound stopped —
no need to leave the screen and come back.

■ Also
Rehearsal's NEXT cue now steps up when a section has five seconds left, which is closer to
the moment you actually need it.
Subscriptions add a yearly plan, cheaper than twelve months of monthly. If you already
subscribe monthly, nothing changes for you.

### 1.1.0 — 2026-08-25

This one is for the people who sing.

■ A new "Lead sheet" view
Rehearsal now has three views: chart, lead sheet, lyrics.
The lead sheet is one line per phrase with the chords sitting above the words — the
line you are on is pinned to the top, and everything below it is what is coming.
No more switching between "where are the words" and "where are the chords".
On an iPad on a music stand the type runs a size larger, so it still reads from a step back.

■ Pickup bars
Songs whose first phrase starts before the barline can be written down properly now.

■ More of it is free
Joining someone else's room no longer needs a subscription — the person you called in
to rehearse should not have to pay to show up.
Video practice and on-device stem separation are free too.
The subscription now covers three things: the AI transcriber, hosting a room, PDF export.

■ Also
Stem separation uses half the memory, so long songs no longer quit partway.
A room code that cannot connect tells you within eight seconds instead of spinning forever.
