Band-In-A-Box 2025 UltraPAK MAC- Auto Accompaniment Software for Musicians, Songwriters & Pros

Band-in-a-Box from PG Music is the songwriting and accompaniment software that builds a full band arrangement for you. Type in a chord progression, pick a style, and Band-in-a-Box generates piano, bass, drums, guitar and strings parts that follow your changes automatically. It is a practice partner, a demo studio and a backing band in one program for Mac.

The UltraPAK: the complete library on day one

The 2025 UltraPAK is the top tier package for Mac, built for players and producers who want the whole RealTracks catalog from the start instead of buying add-on sets piece by piece. It loads in with 4,700+ RealTracks and RealDrums and 7,000+ Styles, both MIDI and RealStyles, spanning jazz, rock, pop, country, blues, folk, Latin and world. Add 320+ MIDI SuperTracks, 300+ MIDI Soloists, 200+ MIDI Melodists, 160+ Artist Performances and 1,100+ Loops and you have a virtually complete session band built into the software.

New in the 2025 edition

2025 introduces the BB Stem Splitter, which separates any audio file into individual bass, drums, guitar and piano, and vocal stems for remixing and rearranging. It also adds new Soul Jazz RealTracks, an expanded Playable RealTracks library, and added SynthMaster sounds and styles.
