The event will feature four main stages alongside a wide programme of daytime activities aimed at young people and families.
Attractions include sports sessions, inflatables, cycling displays and a youth information area promoting local and national services.
A new sports zone, supported by Commonwealth Games funding, will offer activities such as climbing, curling and mountain biking, delivered by qualified coaches.
Alongside the big names, a number of emerging local artists are set to perform.
The festival will also host The Toon, an interactive learning experience tackling issues such as health, crime and substance misuse.
Organisers and Police Scotland stressed the event would be alcohol free, with security checks in place to maintain safety.
