Features
Everything a player piano needs, in your pocket.
Built for player pianos and digital pianos with Bluetooth MIDI adapters, and just as happy playing through your iPhone's speaker.
Playlists
Arrange songs in any order, shuffle, repeat one or all, and set a pause between tracks. Perfect for recitals, parties and background music.
Key, tempo & volume
Change the key up or down two octaves, slow songs down for practice or speed them up, and set the volume. Settings are saved with each song.
Every track, your way
Mute or solo individual tracks — practice the left hand while Cadence plays the right. Rename tracks, swap instruments, and follow along in the piano roll.
Bluetooth MIDI
Pair a Bluetooth MIDI adapter or keyboard right inside the app and send playback to your piano. No piano? The built-in sound library plays every song.
Plays like a music app
Keeps playing with the screen locked. Control it from the lock screen, Control Center, the Dynamic Island or your headphones. Pauses for calls automatically.
A closer look
Simple on the surface. Deep when you need it.
Made for player pianos

Works with Bluetooth MIDI adapters plugged into player pianos and digital pianos, and keyboards with Bluetooth MIDI built in.

Questions & answers
Which files can Cadence play?
Standard MIDI files with the .mid or .midi extension (type 0 and type 1). Files up to 10 MB can be imported; most songs are well under 1 MB.
How do I add songs?
Open the Library tab and tap +. Choose one or more MIDI files from Files, iCloud Drive, Google Drive, Dropbox or any other storage app. Cadence keeps its own copy, so songs stay available even if the original file moves.
How do I connect my piano?
Plug a Bluetooth MIDI adapter into your piano (or use a keyboard with built-in Bluetooth MIDI) and turn it on. In Cadence, tap the antenna button on the Player tab and choose your device. Playback then goes to the piano instead of the phone's speaker.
The piano isn't playing anything.
Check that the adapter is powered on, within range, and shows as connected in Cadence. Some adapters connect to only one app or device at a time, so close other music apps and try again.
Can I change the key or speed of a song?
Yes. Open a song's details to change its key (up to two octaves up or down), tempo (25% to 200%) and volume. These settings are saved with the song.
Does music keep playing when my phone is locked?
Yes. Use the lock screen, Control Center, the Dynamic Island or your headphones to pause, skip or scrub. Playback pauses automatically for phone calls and when headphones are unplugged.
Do I need a piano to use Cadence?
No. Every feature works through your iPhone's speaker or headphones using the built-in General MIDI instrument sounds.
How do I delete my songs and data?
Delete songs and playlists inside the app, or remove Cadence from your iPhone to delete everything. Cadence stores nothing outside your phone.
Cadence Privacy Policy
The short version: Cadence does not collect, store on our servers, share or sell any personal information. Everything the app keeps stays on your iPhone.
Cadence is an iPhone app made by pearGate (“we”, “us”). This policy explains what happens to your information when you use Cadence.
Information we collect
We do not collect any information from Cadence. The app has no user accounts, no analytics, no advertising, and no third-party tracking or data-collection tools. Cadence does not connect to the internet to send us anything.
Information stored on your device
To work, Cadence keeps the following on your iPhone, inside the app's own private storage:
- copies of the MIDI files you choose to import;
- your song names, playlists, and playback settings (such as key, tempo, volume, and track instruments).
This information never leaves your device through Cadence. You can delete individual songs and playlists in the app, or delete everything by removing the app from your iPhone. If you use iCloud Backup or back up your iPhone to a computer, this information may be included in those backups under your Apple settings; we cannot access it.
Files you import
When you import a song, you pick the file yourself with the iOS file picker. Cadence can only read the files you choose, and copies them into its own storage. It cannot browse your other files.
Bluetooth
Cadence uses Bluetooth only to connect to MIDI devices you choose to pair, such as a Bluetooth MIDI adapter on a piano, and to send music to them. We do not use Bluetooth to determine your location or to collect information about nearby devices.
Crash reports
If you have turned on “Share with App Developers” in your iPhone's Analytics & Improvements settings, Apple may share anonymous crash reports and usage statistics with us. These help us fix problems and do not identify you. You can turn this off at any time in Settings > Privacy & Security > Analytics & Improvements.
Purchases
If you buy Cadence or anything in it, the payment is handled entirely by Apple. We never see your payment details.
Children's privacy
Cadence is suitable for all ages. Because we collect no personal information, we do not knowingly collect information from children under 13 (or the equivalent age where you live).
Your rights
Wherever you live, including under the GDPR in the EU and UK and the CCPA in California, you have rights over personal information a company holds about you. Because we hold no personal information from Cadence, there is nothing for us to access, correct, delete, or transfer. Everything Cadence stores is on your device and under your control.
Changes to this policy
If we change how Cadence handles information, we will update this page and the effective date above before the change takes effect.
