The short version -- you can easily find out more on-line with Google.
At one time Cakewalk was among the very top pro audio software packages available. It was maybe the 1st to offer full MIDI support in Windows, allowing you to use high quality MIDI instruments or voices with a midi input device like a keyboard, & letting you create .wav audio files using them, in addition to non-MIDI DAW [Digital Audio Workstation] features.
At any rate the DAW market got more crowded, with several new top end contenders, Cakewalk wound up being bought by Gibson, the guitar folks, who, finding themselves in financial trouble, started cutting development & selling assets. When they stopped Cakewalk development entirely, a new company called Bandlab bought it.
Bandlab was created by the musician son of a Very rich father, is continuing Cakewalk development, and giving it away free.
