ABSTRACT

A California-based computer software company, Adaptec is best known for its compact disc burning programs, most notably Easy CD Creator. Due to its user friendly features and the decision of leading CD-RW drive manufacturers such as Hewlett Packard and Ricoh to bundle OEM versions of Easy CD Creator with their various models, Adaptec enjoyed considerable success from the mid-1990s into the first decade of the 21st century.

A type of recording in which a vocal or instrumental part of the score is omitted, to enable the listener to participate in the ensemble. It seems that the earliest specimens were practice discs issued by the Tilophane Co. in Austria in 1935. Parlophone made aria records without the voice parts in 1938. Columbia issued such records under the name Add-a-Part, covering an extensive repertoire in the mid-1940s. The missing parts were graded as easy, medium, or difficult to play. Add-A-Parts were no longer carried in the 1947 catalog. In the LP era, a label named Music Minus One offered a series of rhythm accompaniments for singers or soloists to complete. There was a similar German series, Spiel Mit (DGG, 1948). Recent practice discs concentrate on the popular music field, providing rhythm backups in various genres (e.g., releases by the Ventures in the 1960s on the Dolton label). The Music Minus One label is perhaps the leader in the field of this type of recording.
