This interactive CD-ROM, geared toward the beginning user of ACID®, is meant to help the musician get up and running quickly on this powerful software. ACID CSi Starter utilizes an interactive environment for learning by providing a vehicle for the user to see/hear an experienced user take them through the steps of producing a song. ACID is a quality, digital music application aimed at the hobbyist and professionals interested in loop based music production. It enables musicians to simply select audio loops from an explorer window, drag them onto the program's track view, and arrange them into multiple-track projects. This CSi Starter is not super technical, but provides enough background information to keep users on track. The structure of the movie tutorials are designed to maximize a clear and concise delivery of the information. ACID CSi Starter is applicable for both ACID PRO 4.0 and Screenblast® ACID 4.0 versions.
