Price: You will find that a lot of people are using paid sample libraries or paid VSTS. I’ve been in sessions where we had over an hour of work just get lost and it totally sucks. You don’t want to bog down your computer as there’s nothing more frustrating than having your computer shutdown mid-session.
How Much Use: If you’re installing a massive sample library for Fl Studio that you rarely end up using, you’re better off uninstalling as they can be CPU intensive. While it is great to just write at a piano, introducing crazy plugins can really change the integrity of an entire song. They inspire me when I’m writing parts or songs. Presets: I love to have VST libraries that have a ton of presets. With that being said, try and find the highest quality sounds in each VST that you for FL Studio. Sound Quality: If you choose to go the free route, that is totally cool, however, you will definitely run into some abysmal options.
