What is the Zodiac III Eternal Expansion? This ringtone extension includes a new selection of ringtones that have the same approach as the main collection. We’ve saved some of our favorite loops the team created for the Zodiac III to add to this expansion pack. The melodies in it give you even more options to work with, with many different vibrations to choose from. Each tune comes with original loops and MIDI to give you complete control over every sound.
