Show Control and Playback

This is perhaps the most confusing, as playback systems develop and change rapidly, become obsolete just as rapidly and are based on a range of technologies.


Nearly all the items in this section have emerged in the last 10-15 years. Only 15 years ago the most popular playback medium was 1/4” reel-to-reel tape.


During the 1990’s, playback systems were cobbled together from a range of devices originally designed for other purposes, notably Samplers.


Over the past 10 years computers have got powerful enough to take on playback and processing duties properly, and software solutions designed specifically for theatre are more prevalent.
