I often say BiaB is the best worst software - or should that be worst best software ? - I've ever used. A toolbar that crams dozens of tiny icons, almost no visual hierarchy, dated visual style, waaaay too many dialogs (dialogs within dialogs!), zero discoverability, inconsistent labeling, basic features missing...I could go on.

Instrumentalists used it generate tracks to improvise or solo with for example, and songwriters found it useful to essentially have a full band at their beck and call while composing. The interface has become kind of disjoint.

It would generate pretty darn good instrumental tracks, good enough that I could use them as part of a mix.
