While you can run FL Studio on 4GB of RAM, it’s not nearly enough to produce on effectively, especially if you factor in memory-intensive libraries such as Massive and Omnisphere. To avoid running into constant slowdowns from memory swapping, you’ll want to have at least 16GB of RAM on hand. There are of course cases where you would need upwards of 32GB, however, most people won’t have tons of orchestral samples to justify the cost.
