Gravitation only works if you already own Hybrid 3, and that's the sentence that decides whether this review is even relevant to you. If you don't have the base synth, stop here. If you do, at $19.99 this is a 100-preset expansion covering arps, pads, leads, rhythms, and FX across house and cinematic territory, with mod-wheel morphing baked into most of them. That's the pitch. Whether it's worth it depends almost entirely on how much mileage you're getting from Hybrid 3 right now, and what's annoying you about your current preset options.
The Catch Up Front
The requirement is non-negotiable: you need AIR Music Hybrid 3 installed and working. That sounds obvious for an expansion pack, but it matters here because Hybrid 3 carries some well-documented baggage.
Reviewers report crashes in Logic 10.6.2 during program changes. Users keep running into activation headaches, especially on older licenses. There are compatibility complaints across Windows 11, specific Ableton versions, and FL Studio builds that can corrupt project files. The GUI doesn't scale, so on a 4K monitor, everything looks like it was designed in 2008.
None of those problems come from Gravitation. But if your Hybrid 3 setup is already rocky, adding an expansion isn't going to fix the foundation. Sort the base install first.
What You Get If You Clear It
One hundred presets. That's the whole package.
The breakdown covers arps, pads, rhythms, pad FX, FX, leads, and lead FX. The developer describes this as a superb library of highly inspiring presets covering genres from house to soundtrack. Those are their words, attributed where they belong.
The feature that actually makes this interesting is mod-wheel responsiveness. On the majority of presets, the mod wheel triggers morphing and subtle character changes in the sound. You're not just scrolling through static patches. Push the wheel mid-phrase and the sound shifts. That kind of built-in expressiveness is what separates a useful preset library from a folder you audition once and forget.
If you're working on synth expansion packs and whether they're worth adding, the mod-wheel behaviour is one of the things to look for. Gravitation does have it.
Where It Shines
The genre range is the honest strength here. House to cinematic soundtrack is a wider lane than most single-artist or genre-specific expansions attempt. You could load an arp for a club track, then pull a pad FX for an underscore cue, and both live in the same library.
A hundred presets is a reasonable number. It's not the 1,200-plus of the full Hybrid 3 factory library, but it's focused. Smaller, curated libraries often get used more than massive ones because the signal-to-noise ratio is better. You find what you need faster.
The mod-wheel design is where we'd spend our time. Load a pad, get your level right, then slowly push the wheel while a chord holds. That's where you find what this library actually does that a static preset collection doesn't. It rewards hands-on playing rather than fire-and-forget auditioning.
At $19.99, the entry point is low enough that the value case is straightforward for anyone already invested in Hybrid 3.
Against the Field
Hybrid 3 sits in a category that reviewers compare against Serum, FM8, and u-he Bazille. Those comparisons are about the engine, not the expansion. But the engine comparison matters here because it sets the ceiling on what Gravitation can do.
Serum's wavetable approach gives preset designers more texture options. FM8 opens up far richer harmonic complexity. Bazille offers deeper modulation routing. If you're already feeling like Hybrid 3's synthesis engine is hitting a wall, a preset pack built on that engine won't break through it.
Where Gravitation wins is simplicity. No new synth to learn, no additional CPU overhead from a second plugin. If you already have Hybrid 3 in your signal chain and you need fresh material, this costs less than a meal out. Compared to buying a second synth for variety, that's hard to argue with.

Who Should Buy This
This one genuinely splits down the middle. Here's how to decide fast.
- ✅ Buy if you use Hybrid 3 regularly and find yourself cycling through the same presets.
- ✅ Buy if you work across house and cinematic genres and need one library that covers both without switching plugins.
- ✅ Buy if you play live or automate the mod wheel, because the morphing behaviour is built for that.
- ❌ Skip if you don't own Hybrid 3. This doesn't work without it, full stop.
- ❌ Skip if your Hybrid 3 install is already unstable. Fix that first.
- ❌ Skip if you're looking for deep sound-design tools. These are finished presets, not a modular system.

Score Breakdown
| Category | Score | Notes |
|---|---|---|
| Sound Quality | 3.5/5 | Mod-wheel morphing adds real expressiveness; the engine ceiling limits how far presets can push |
| Value for Money | 4.0/5 | At $19.99 for 100 mod-responsive presets across two genres, the maths works for existing Hybrid 3 owners |
| Ease of Use | 4.0/5 | Load and play; the mod wheel does the heavy lifting |
| Features | 3.0/5 | 100 presets, seven categories, mod-wheel morphing; there's no deeper design layer here |
| CPU Efficiency | 3.5/5 | Inherits Hybrid 3's light CPU footprint, though the base synth's stability issues remain a risk |
| Overall | 3.4/5 | Solid, focused expansion for committed Hybrid 3 users; frustrating if the base synth is already giving you trouble |
Alternatives to Consider
If you're not locked into the Hybrid 3 ecosystem, there are broader options worth knowing about.
The Marco Lys Hybrid 3 expansion covers different genre territory within the same engine. If Gravitation's house-to-cinematic range doesn't fit your workflow, that one might be a better starting point.
The Fresh Energy Hybrid 3 expansion is another option in the same family. Comparing the genre focus across these before you buy any single pack is worth five minutes of your time.
For a look at whether expansion packs broadly justify their cost, our guide to Maschine expansion packs covers the logic of ecosystem lock-in, and a lot of it applies here too.
If you're open to switching engines entirely, Serum's third-party preset market is enormous and the base synth has none of Hybrid 3's stability complaints. That's a bigger investment upfront, but the library options become much wider.
The Honest Bottom Line
Gravitation is a straightforward bet at $19.99 if Hybrid 3 is already a stable part of your setup. One hundred presets with mod-wheel morphing, spread across house and cinematic territory, loaded and ready to play. That's a satisfying proposition for the right buyer.
But the frustrating truth is that this expansion can't fix what's broken underneath it. If Hybrid 3 is crashing your DAW, corrupting sessions, or looking ridiculous on your 4K display, Gravitation won't change any of that. You'd be adding presets to an unstable instrument.
Buy it if Hybrid 3 works reliably for you and your current patch library feels stale. Skip it if you're on the fence about Hybrid 3 itself. The expansion follows the synth. Whatever relationship you have with that synth, this pack inherits.

Frequently Asked Questions
Do I need Hybrid 3 to use the Gravitation expansion?
Yes. Gravitation requires AIR Music Hybrid 3 to run. It's an expansion pack, not a standalone instrument. If you don't own Hybrid 3, this won't load in your DAW. Check your Hybrid 3 version is up to date before purchasing.
How many presets are included in Gravitation?
The library contains 100 presets. These span arps, pads, rhythms, pad FX, FX, leads, and lead FX. The coverage is designed to work across genres from house through to cinematic soundtrack work.
Does the mod wheel do anything useful in Gravitation?
On the majority of presets, yes. The mod wheel is set up to trigger morphing and subtle character shifts in the sound. If you perform live or automate the mod wheel in your DAW, that's where this library earns its keep. Static auditioning won't show you the full picture.
Is Gravitation worth buying if I already have Hybrid 3's factory presets?
It depends on whether the factory library is covering your needs. Hybrid 3 ships with over 1,200 presets, so if you're still working through those, there's no rush. If you find yourself hitting the same patches and wanting something fresh across house and cinematic territory, Gravitation is a low-cost way to add 100 more options without learning a new instrument.
