Here's what's new in VividTracker 1.3:
New feature: AutoChord Keys. This is an amazing new feature that adapts the keys to only show the pentatonic scale for the current AutoChord. The last key (blue colour) will show the current chord. This makes it super easy to write music that goes in harmony with the current chord. You turn on AutoChord Keys by pressing the ACK-button on Screen 6.
