Back in the day, our little group ran a lot of shows off Show Cue System. Haven’t used it in several years now, so it may have morphed into something else, but for our uses it was great. Cheap (used to be free), did what we needed, capable of doing video/projections as well, and ran on a Win laptop (which was what we had). Source: over 1 year ago
