SFX is the leading live entertainment, sound playback software application. The typical venue for SFX is theatre, but it is also used by theme parks, magicians, and other related venues that require the playback of music and sound effects.
The software is registered to a single computer. Alternatively, you can just about any USB jump drive (i.e. memory stick or flash drive) to store the registration on instead. This will allow you to run the software on any computer you plug the USB drive on.
Multiple licenses can be stored on one USB drive and easily moved back and forth allowing a designer to "lend/rent" a license for a period of time. For example, you can transfer a license from your USB drive to the theatre computer for the run of a show and transfer it back at the end of the run!
