Any production work carried out by Cambridge-MT is performed as 'work for hire', and as such no claim is made on the music creator’s compositional or sound-recording copyrights. Although mixes and project/master files are backed up by Cambridge-MT as a matter of course, ultimate responsibility for archiving all aspects of any mix project lies with the client. Cambridge-MT encourages clients to back up important files in at least two different digital formats. Cambridge-MT reserve the right to use up to 30 seconds of any material worked on by Cambridge-MT for demonstration and/or publicity purposes.
