Instrument automation gives us the important capability of establishing a solid archive of an electroacoustic composition (or “song”). That is, a piece can be stored and shared as a VCV Rack along with its automation data. Such as collection can be used to re-perform a song. This could mean changing the automation data or changing out modules while using the same data.
Note that a “MetaSong” may require more than just the rack and automation data. Modules such as samplers, for example, may require that the samples be including. And, since “A song is a musical composition intended to be vocally performed by the human voice“, it’s possible that a song could be the combination of a VCV Rack patch, the automation data, support files (such as samples) and a recorded track (such as live Vocals, Guitar or Trumpet). The MetaSong is all of this.
