Rapid Synth is a fantastic power synth VST plugin, with an astonishing sound quality and a vast collection of timbres. The plugin merges a sampler instrument with a wavetable synthesizer, transforming it into an extraordinary tool that can create intricate and unparalleled sounds.

Although this is not necessarily a new invention, the sheer amount of patches (8 total), the fantastic library of samples, and the modulation possibilities give Rapid Synth its edge. For instance, you can have 8 patches, with the same 4 OSC, samples etc. all layered on top of each other, allowing you to create incredibly in-depth sounds.

Rapid Synth utilizes wavetable synthesis and a great sample library, much like Omnisphere, for crafting intricate and unique sounds with its modulation features. While it leans towards EDM, it could be viewed as a more affordable substitute for Omnisphere.

Although it doesn't match the exceptional sound quality of Omnisphere, Rapid Synth is the ideal tool for crafting high-energy EDM tracks with a distinct clarity and punchiness that packs a real wallop, while Omnisphere is best for creating rich, textured soundscapes with a cinematic flair.

Rapid Synth offers an extensive range of functions, such as 250 wavetables, 22 effects, three oscillators, four envelopes, four LFOs, four sequencers, and an arpeggiator that reads MIDI. Although it is one of the most complete software synthesizers accessible in the market, it has not achieved much recognition in the music production community, but we have no idea why, because it's incredible for the price.

The array of available sounds in the preset library is extensive and impressive. One noteworthy category is Melody which features ready-to-use MIDI files. It's advantageous because it permits simultaneous playback of distinct sections like a chord progression, a bass line, and an arp. Though the sequencer draws attention, it may pose a few difficulties during operation; and the preset library may start to feel repetitive.

The Rapid Synth is skilled in generating lofi and cinematic audio effects, but its real forte manifests when it comes down to producing crisp and impactful EDM sounds.

When I'm aiming for a sound that is more electronic in nature, I find that Rapid Synth is the perfect tool to incorporate in my workflow. It shares similarities with Omnisphere in terms of functionality, but I often refer to it as the more economical choice (or the poor man's Omnisphere)

It's a fantastic, affordable entry synth to the world of power synthesis.

βœ… Incredible modular environment providing a tonne of different synths, effects, modulators and more to choose from

βœ… Possible to code your own instruments and effects (similar to those who know about Ableton's MaxMSP)

βœ… You can patch any series of instruments and effects together, linking them up with wires how you would in a modular environment

βœ… Included with Komplete collection, which comes with loads of instruments, high quality samples, synths and more

βœ… Moog synth emulation included in the 70+ included instruments 

βœ… If you have a Maschine or a Komplete Kontrol, this perfectly links with the hardware, allowing you to create patches using your hardware instead of mouse clicks

❌ Very difficult to learn completely. Initially the modular aspect is easy to pick up and NI have made it simple, but the coding and creation of your own blocks is where it starts to get veteran difficulty

❌ Blocks can be intimidating for beginners, and may require a significant amount of time and effort to master.

❌ Very CPU heavy when you start creating in-depth sounds

❌ Very expensive for a modular synth, but definitely one of the most customisable and cheapest available considering you don't have to purchase 3rd party modules and can create your own or use the vast user-library submitted stuff

Native Instruments' Reaktor is a modular software synthesiser that has many built-in pre-built module blocks, you can string together in any order you like to create sounds, much like you would in a normal modular synth.

But, what sets Reaktor apart from the other modular synths, is the possibility (much like Max4Live) to code your own blocks in the software and share them to the community online.

This is great, because, if you are a tinkering sound designer, you can create anything you like. However, even if you're not a coder/technical guy, you can browse the massive library of modules that have been built by the community.

What makes this so great is the integration with the software. You can directly search for modules inside the application without leaving, and it's extremely smooth. You can download Moog emulations that have been built, special reverbs and loads more. It's one of the most limitless synths in terms of sound design, but is quite difficult to learn and very expensive.

Reaktor comes with a user-friendly interface that enables the creation of customizable modular synthesizers, sequencers, samplers, and various other sound-creating devices. Its modular system allows users to produce unique moments and audio effects that would be hard to come by in other software or hardware.


Compatibility: Win8, Win10, Win11, Apple Silicon, macOS 10.13+ VST, VST3, AU, AAX, 64-bit

❌ The editing of sounds is very limited compared to other synthesisers, and it's much like a more advanced sampler. Some people might not like this factor.

❌ Quite expensive for producers coming in at $249 just for a starter edition, going all the way to $4069 for complete

❌ Takes up a huge amount of HDD space

❌ Not many effects included compared to other synths

reFX Nexus, is a highly adaptable and user-friendly tool with a vast selection of superior presets tailored to EDM. Its extensive range of pre-made, mixed, pristine sounds makes it the perfect solution for those in need of high-quality audio samples and synths for production.

The reFX Nexus is a synthesizer that boasts both superior sound creation capabilities and remarkable sound quality. Its effortless configuration and user-friendly controls are also noteworthy features, and the synth's graphics only serve to further elevate the overall user experience.

Although it may not provide the utmost level of synthesizer personalization, the reFX Nexus stands out for its ease-of-use and convenience. This synthesizer is perfect for those who desire top-notch sounds and presets without the need for extensive adjustments.

This music tool is highly favored by EDM producers, as it caters exclusively to their needs. It presents an array of features similar to Kontakt or Komplete. If you're looking for quick and exceptional EDM sounds, this tool is amongst the top options out there.

However, for some, the potential purchase may not seem worth it due to both the restricted sound editing features and its high cost.


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.

To recap, here's the complete list of best synth plugins for FL Studio:

  1. Diva
  2. Serum
  3. Rapid Synth
  4. Falcon
  5. Phase Plant
  6. Pigments
  7. Waverazor
  8. MPowerSynth
  9. Massive X
  10. FM8
  11. Modular
  12. Reaktor Blocks
  13. Nexus
