First off, if you need a prompter program to do single files, such as speeches, awards, etc, then there are several inexpensive programs reviewed on Macupdate that will suit your needs. Shadowscript is primarily an teleprompter software that utilizes multiple files to build a concert performance, with the ability to edit, and source, unlimited files to add to a show INSTANTLY. This is important when a performer decides to change up the show mid performance, and if notes need to be added when guest stars are added last minute so notes need to edited into existing scripts.
I am proud to say that this software is currently being used by several Grammy winning artists and has used on several nationally televised live performances.
As an operator, and not a programmer, I sought an existing program for my needs. When none existed, it took great efforts for find a programmer willing to custom design a software addressing live performance issues.
Any feed back to the demo would be appreciated since I feel that all software is, pretty much, a work in progress. Please feel free to email me at DLee@shadowscript.com
