Notion

With over 10 years in the App Store, Notion Mobile is a free, award-winning music composition tool for iOS, iPadOS®, macOS and more! You’ll effortlessly create dynamic compositions in traditional musical notation or guitar tablature with its intuitive touch-based interface and incredibly broad editing capabilities.

With a user-friendly interface and simple interactive piano keyboard, fretboard, drum pad, and even optional Handwriting Recognition, Notion Mobile makes it easy to get started composing your music. You can also hear your music performed with the most realistic playback possible, using real audio samples recorded by the London Symphony Orchestra at Abbey Road Studios.

Notion Mobile is a native cross-platform app, meaning you can write anywhere on any device without requiring a constant Internet connection. And when you’re back online, you’ll be able to sync your work across multiple devices — either through your preferred cloud provider, or through the optional wireless transfer between PreSonus applications on any device. Start your work on one device and finish it on another. Once you are happy with your creation you can share the Notion file, or export as MIDI, MusicXML, PDF or as an audio file.

Compose, edit, and play back your music performed with real piano and orchestral samples recorded by the London Symphony Orchestra at Abbey Road Studios — along with outstanding sampled guitar, bass, drums and other popular instruments. And when you’re ready for more sounds, you’ll find the extensive library of Notion Add-on Soundsets to purchase as part of the Feature Bundle. To save space, the initial app download contains just piano — you can then manage which of the bundled Soundsets to have on your device or keep in the cloud, just tap on Sound Installation.

Notion has been featured in various Apple campaigns including the 2014 YourVerse television commercials and has won several awards, including a prestigious music industry NAMM TEC Award for Best Smartphone/Tablet App.
