QLab 3 Show Control

Book Description

Used from Broadway to Britain’s West End, QLab software is the tool of choice for many of the world’s most prominent sound, projection, and integrated media designers. QLab 3 Show Control: Projects for Live Performances & Installations is a project-based book on QLab software covering sound, video, and show control. With information on both sound and video system basics and the more advanced functions of QLab such as MIDI show control, new OSC capabilities, networking, video effects, and microphone integration, each chapter’s specific projects will allow you to learn the software’s capabilities at your own pace. Tutorials and additional resources are featured at www.focalpress.com/cw/hopgood.
