Metro is a fast-operating, easy-to-learn high-powered sequencer for the design of professional audio projects. It's a complete and integrated MIDI, audio and video production system.

Metro's main engineering design goals are stability and performance respectively.

The audio system supports up to 128 audio tracks. Each track, aux buss or mixer channel can have its own effect chain. Chains can be made up of VST effects and/or AudioUnits (OS X only). VST 2.x is supported. All effects can be automated. Real-time editing is encouraged. Software audio play-thru allows the original audio to be recorded regardless of what plug-ins are currently in use.

The MIDI system has been around since the 1980's. Metro combines all the functionality expected from a professional MIDI sequencer with a simplified interface and innovative ideas, such as the Rhythm Explorer and the algorithmic Note Spray Paint tool.
