Band-in-a-Box is well-liked by customers and gets good reviews on Amazon.com as of 2015. The software, created by Paul Gannon of PG Music, Inc, is widely used by beginner and professional level musicians to automatically generate complete arrangements of piano, bass, drums, guitar and horns to accompany them.
The number one complaint from reviewers about the MIDI music arranger is that the user interface is cluttered and difficult to navigate. The software is packaged with multiple add-ons and extras that can sometimes make it feel overwhelming to beginner level users. There are several different versions of the software available, including an upgrade in 2015, which features video functionality with YouTube compatibility and an enhanced GUI.
