Cakewalk is a company based in Boston, Massachusetts that develops music production software. Their best known product is their comprehensive music sequencer SONAR, which is designed for use by professionals. SONAR incorporates multi-track recording and editing of both audio and MIDI.
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.
