Cakewalk (sequencer)
Produced by Cakewalk, (formerly known as Twelve Tone Systems, Inc.) Cakewalk was the name of their flagship MIDI sequencer, first for DOS and since 1991 for Windows 3.0. Early versions of Cakewalk for DOS (up to 3.0) required the intelligent mode of the MPU-401 card and could not be used with today's clones, while later versions (since 4.0) relied on dumb UART mode only. Cakewalk was renamed Cakewalk Pro at some point, and later into Cakewalk Pro Audio when support for digitized audio was added.
