ChordFlow gets a really big update adding a host of new features for users. There’s a lot to show, so here are all the details:

Each ChordFlow song section can now have up to 4 melody tracks in addition to 4 arpeggio tracks. You can now create complete song ideas with chord progressions, arpeggios, and melodies. The new melodies are edited in the separate (from arpeggio) grid. You can specify scale of the melody grid and configure the length and the rate parameters. The chords that you configured in the chord progression editor will be shown in the melody grid view below the note grid. And also for more convenience, chord notes will be highlighted with grey rounded bars allowing you to see which notes of the melody matches the corresponding chord.

There is now a track control panel in the main view, at the bottom, where you can specify destination of each track and mute/solo individual tracks. This settings are now stored individually for each song.

You can now loop a region when you are in the arpeggio or melody editor. To add a loop region, tap on the timeline bar above the note grid. After that, the loop with the default length of 4 steps will be added. You can then move the loop region around dragging it by its center or you can stretch and squeeze it by dragging it by its ends. To remove the loop region just tap on it again. The loop region is only active while you are in the editor view. When you move back to the main view, the loop is automatically removed.


  • Remove(Trash) button in arpeggio and melody editors now removes only the selected track. And there is no moro annoying confirm. If you tap remove button accidentally, you can restore the deleted track with the undo button.
  • Line tool and delete tool behaviour changed a little. Before this update, when you started to draw a line or delete a region, you could only extend the already drown region. Now it behaves more expectedly. If you have drawn a line further than you needed you can no move back to make it smaller
  • Arpeggio grid max length increased to from 32 to 64 steps.
  • Color scheme changed. After introducing 4 new colors for melody tracks, I decided to switch to more neutral background colors, as it was not looking very good on the original blue schema.
  • Bug fixes
