Here is a list of the best free VSTs available on the web at the moment. While much of the fun comes from discovering new gems yourself, sometimes it is beneficial to skip straight to the good tools. This list should be enough to give you a good start if you are new to production, and perhaps add a refreshing selection of sounds, if you are more established.

Please note that all of the plugins were free at the time of writing. Some may require an account to be made on the site of download. I am only linking to established sites and have tested all of these, but please ensure your antivirus is up to date!
