▻ Progression Mode

Compose progressions, playback them and see the chord relations within the circle of fifths. You can put together 4-8 bars and repeat them. In this way you can compose two parts (like verse and chorus) and hear how they would sound like together!

Export progressions as MIDI file.

You can tap in the playback tempo or adjust in manually (40 - 240 bpm). Playback progressions with or without click and/or piano. Practice progressions along with the circle of fifths. Your progressions will be visualized in the circle. There are some predefined common progressions or you can compose your own. You can pick chords from the current key for your progressions and adjust the mode to ionian, aeolian, dorian, phrygian, lydian, mixolydian, locrian or even harmonic and melodic minor.
You can add additional tones within key to each chord.
You can display either the chords, roman numerals or both.
Once you've composed a progression you can quickly change the key for the whole progression.

- Grand Piano
