## What is Chordi?

Why I created Chordi?

As a bass and ukulele player, I always found the piano the easiest way to explore theory—if only I could actually play it! But every tool I tried felt too complex and fiddly, getting in the way of creativity. So, my inner nerd took over, and Chordi was born—an app that makes music exploration easier, no matter your skill level. Whether you’re a beginner or a seasoned musician, Chordi helps you unlock new ideas, spark your creativity, and build music effortlessly.

I believe music and education should be accessible to everyone. That’s why Chordi is FREE FOREVER—no subscriptions, no locked features. Just a tool to help you explore and create music without barriers.

What to expect?

Supported Devices (iPadOS/iOS)
- Optimized for iPad in landscape orientation
- iPhone Support (for those who dare to create music on-the-go, even in portrait mode!)
- Light & Dark Mode 

Just Play!

Tap notes on the keyboard or create full chords effortlessly.
- Press and hold chord quality buttons (like maj7 or m) before selecting a root note.
- Choose different chord inversions and voicings.
- Add bass notes or octaves up/down with the Octaver and Bass buttons.
- Experiment with Hold mode to layer melodies over chords.

Creative Modes

Take your creativity even further with these powerful modes:
- Free Mode – Play freely—just tap notes or build chords without any restrictions.
- Key Mode – Select a scale and key, and let Chordi guide you through fitting chords. From triads and sevenths to secondary dominants and modal interchange, you’ll always have the right options at your fingertips. Chordi even suggests what to play next based on chord progression rules.
- Replay Mode – A creative alternative to traditional loopers—perfect for those who find the red record button intimidating. Any notes played in Free Mode or Key Mode are automatically stored. Enter Replay Mode to revisit your ideas, delete individual events, add a gap at the end for a smooth loop, or export your session as a MIDI file. Capture inspiration without pressure and refine your ideas with ease. Beware, leaving that mode starts recording again.

Rhythm Modes

Explore chord rhythms and experiment with musical textures in these modes:
- Normal Mode – Play single notes or full chords with available modifiers.
- Arpeggiator Mode – Transform chords into arpeggios. (Experimental)
- Strummer Mode – Strum your chords like a guitar or harp. (Experimental)

Customize

- Fine-tune sections of the app to fit your needs. Reorder, resize, and modify elements to create your perfect workspace.

MIDI Integration

Plug in your MIDI keyboard or connect Chordi to your DAW (USB MIDI input/output supported).

Sound Engines

Let’s make some noise.Let’s make some noise.
- Soundfont Player – Play with handpicked sampled sounds: Rhodes, Wurlitzer, Organ, and Grand Piano.
- Synthesizer – Create your own sounds with Chordi’s built-in synth. (Experimental, may have occasional issues)
- Sound Settings – Control effects and tweak sound parameters.

Note: For the best audio experience, speakers or wired headphones are recommended. Wireless Bluetooth headphones may introduce small latency.

In case of emergency…
- Panic Button – Instantly stop all sounds, reset the audio engine, and clear any highlights.
- Shake device for Help – Always one shake away from guidance.
- Need More Support? – Check out the support page, or reach out directly—I’m always happy to help.

### 5/5 — Great App, Generous Developer

*2025-12-24*

I don’t usually leave reviews but this app and developer deserve praise. First, I appreciate the developer for creating this tool/app free of charge especially in a space and time where everything has a price either through a subscription, one time fee, or through ads that take away from most of the experience, not here. Second, the layout, is the right mix of simple and intuitive. Lastly, it is very versatile and customizable, you can get a huge amount of sounds by messing with the parameters of the synth or piano, figuring this out is what pushed this free app to the next level for me.I think anyone can use this, granted your mileage may vary depending on your need and creativity. I use this mainly to help me practice and compose ideas. Don’t let the price and interface fool you, this is a powerful creative music learning/practicing/composing tool. Thank you again to the developer for creating this and allowing access to everyone.

### 5/5 — Incredible range

You could easily write a score to a game or movie solely using this application

### 5/5 — Great Tool.

*2025-10-12*

Just wanted to say that I appreciate your creating this tool. Useful. I’ve been doing this iOS thing from the get go and this for what it is designed to do does it really well and headacheless. You’re the man.

### 4/5 — Wish Chordi had an AuV3 Connection

*2025-08-18, version 1.2*

Wirklich tolle Chord App um auf dem iPhone zu Jammen. Die Benuzer UI ist wirklich spitze. Ich wünschte die App hätte noch eine AuV3 Anbindung, damit ich sie in diversen Programmen wie AUM oder BAM laden könnte. Oder zumindest eine iAA Anbindung für Audioshare.

### 5/5 — Ok. Wow!

*2025-04-10, version 1.2*

I‘m super impressed by this app. Tried a few apps to find one that fits my chord needs. This one is outstanding. Very well done! Thank you.

### 5/5 — Loved it!

*2025-04-06*

Make it AUv3 and it will be perfect! Looking forward to the future for this one

### 5/5 — Great Songwriting Tool

*2025-04-04*

Easy to use, inspiring app. Play chords to find out what sounds good. Use the MIDI to trigger other apps. I love the midi buffer that automatically records the notes you play, that’s a great feature. I also love how the notes show across the top while playing. Very Useful App! Cheers!

### 5/5 — Really cool app

This app is really well made and it's so much fun to create new tunes.

### 5/5 — Fantastyczna aplikacja

Bez reklam, bez subskrybcji, bez kradzieży i wyciągania danych. Półprostą można się pobawić muzyką

### 5/5 — Fajna Sprawa :)
