Work with channel strip settings in Logic Pro — Apple Support
Channel strip settings (CST files) are specific to each channel strip type. Instrument channel strips feature a number of instrument settings, separated into instrument, GarageBand, and Jam Pack categories. Audio channel strips offer effect routings optimized for particular instrument, vocal, and other processing tasks. Similarly, output and auxiliary channel strips provide channel strip settings for particular mastering or sweetening processes.
