I made this list merging sites from a previous post with some personal addition in order to make a more practical (because in the original you would have to read all the comments) list of website where you can find free vst and what i mentioned in the title. I will update the list with sites that will be mentioned in the original post but you can also tell me something to add down here. Also if you have your personal samples storage like on google drive or mega with some old ones that are no more available on the web, you can contribute!
Link to the original post: https://lmms.io/forum/viewtopic.php?f=4&t=4961
Note: this is not a list about which are the best VSTs or samples but only about which are the best sites where you guys can find it. If you want i will make that list later, let me know. Also this is all about freebies like the original, so don't post cracked materials.
