Originally, there were physical instruments, analog tape machines, and outboard effects processing gear. Then, with the advent of hard disk based digital recording, VSTi and virtual outboard gear appeared in the form of plugins. Then, with the transition from boxed software and toward online distribution, many software companies began to make plugins. Plugins quickly replaced physical equipment and software companies increasingly began to produce newer / better versions of plugins. To notify users of updates, email lists were maintained. However, owing to the amount of spam people receive, plugin companies still need to advertise on the web and in print. ' PluginUpdate' makes the process of updating your plug-ins to the very latest versions so much easier by providing a free, easy-to-use, cross platform app for keeping plugins at their latest version. It's FREE so you've nothing to lose. At the time of writing, it is still in BETA - so, grab a bargain whilst you can.
