Summary

So, by now you should have a wide selection of synth VST plugins to choose from for FL Studio. We’d personally recommend picking one synth and sticking to it, learning it inside and out. If that’s a stock synth, then so be it, just pick one and learn.

If you want something versatile, easy to learn and with great sound design capabilities, we’d pick Serum. You can pretty much make anything in Serum, but it does have some limitations when you get more and more advanced at sound design. We personally still use Serum in all our tracks and productions, but also own other synths for more in-depth sounds. Serum is perfect for low CPU, great sounds, and ease of use.

If you want something to build upon Serum, and that has semi-modular capability, we’d go with Phase Plant. You can blend, analog, digital, FM and other types of synthesis, as well as have more control and power over your sound. However, the filters and effects section is pretty drawn back in Phase Plant.

If you want an analog synth, with semi-modular capability, Diva is the absolute best for this. The emulation accuracy is second to none and you can mix and match different analog synths from different hardware as modules – it’s fantastic. However, if you want precise control over the sound design process, it’s not anywhere near as accurate as something like Serum.

Additionally, if you’re looking for ready-to-use inspiration, check out this roundup of the best free FL Studio templates.
