The COMPOSE ALL app feature creates a new melody and accompanying harmony from scratch. You can use this feature as fresh ideas generator and then tweak the melody.

AUTO MODE - when active the melody is autocomposed every 4 (changeable in Settings) cycles. During playing you can save the composed melody via Save button.

Three types of AUTO MODE are available:

1. When AUTO MODE is active and COMPOSE ALL is selected then both melody and harmony will be autocomposed every 4 cycles. The text below button PLAY will show "AUTO ALL".

2. When AUTO MODE is active and COMPOSE NOTES is selected then melody only will be autocomposed every 4 cycles. The text below button PLAY will show "AUTO NOTES".

3. When AUTO MODE is active and COMPOSE CHORDS is selected then harmony only will be autocomposed every 4 cycles. The text below button PLAY will show "AUTO CHORDS".

The notes and chords are changed using the drop down menus for each note. You can listen for both melody and harmony or only one of them using check boxes in control menu.

If you want to auto compose some notes of melody just check them and press Auto Compose button. Then the notes will be composed for you.

if articulations (dead notes, palm mutes, bends etc.) and power chords can be added to the notes, then this will becomes the best guitar riffs generator.
This app is great for coming up with little tunes. Just keep changing the variables and sooner or later you will get something you will want to work with :)
