Chords that work together.

Audiobus Ableton Link

Suggester is a tool to assist in the creation of songs and chord progressions. This app will help you find chords that work together. It is efficient and fun; use it to build musical phrases that will carry emotion through tension and release.

Simply touch a chord to hear how it sound like. Press the play button to hear the chord progression sequentially and adjust the playback speed.

You can work either forward or backward:

FORWARD - Pick a scale, then build your song from the chords that the app suggests. That's the quickest way to assemble chords that are compatible.

BACKWARD - From the catalog, pick a set of chords that you like. The app will tell you what scales it matches with. After you have selected the scale you want to use, the app can tell you what chords will fit in with the ones you entered before. That is extremely useful in jam sessions!

To spice things up, you can borrow chords from parallel scales.

You can also explore classic chord progressions.

Use Drag and Drop to reorder chords. Hold your finger on an item for a second to start the drag operation. On iPad, you can also drag chords directly from the suggestions to anywhere in your progression.

Swipe a chord from right to left to delete it.

When you're satisfied, save your experimentations for later reference. Export them by email using either a MIDI file or plain text.

Every sound generated with the app is also sent to the MIDI output, configurable in the Options. You can route these notes to another app on your device, or remotely to another computer by setting up a MIDI Network Session. It's also possible to export to a MIDI file or plain text.

In the free version, some of these features are locked. Reach full productivity by purchasing a Full Unlock. You only need to buy it once for all your devices. To unlock your purchase on another device, select "Restore Purchases" in the Options.
