AZS Transitions Vol. 2 sits in the same space as Luftrum's Diva banks and the Diva Digital series, and after spending time with all three, we'd say this one is the most genre-specific of the bunch. That's not an insult. It's the most important thing to know before you buy it.
Resonance Sound built this around the sound of late-90s and early-2000s progressive house and trance. Think Global Underground compilations. Think Sasha and Digweed at their peak. If that sentence either excited you or meant nothing to you, that reaction already tells you whether this library is for you.
It's 150 presets in H2P format. It requires U-he Diva v1.3.1 or higher. It covers pads, basses, leads, plucks, sequences, 80s pop stabs, and film-score atmospherics. We tested it across a two-hour writing session specifically trying to finish an arrangement that had been stalling for weeks. Here's what we found.
How It Compares Out of the Box
The Diva Digital series leans cleaner and more genre-neutral. Luftrum's banks lean warmer and more ambient. AZS Transitions Vol. 2 leans into a specific analog-emulation character that feels like it was built to sound like hardware, not to sound modern.
First impression: the pads are the standout. We loaded three of them back-to-back and each one had a different texture without feeling like random sound design. Someone made decisions about harmonic content and filter movement here, not just preset-dumped a hundred variations.
The basses are raw in the best way. Not polished, not scooped for modern bass. They've got grit around 200-400Hz that you'd normally have to add yourself with a saturation plug-in. We'd still high-pass most of them around 40-60Hz before they hit the mix bus, but the character is already there.
Compared to buying a Luftrum bank, you're getting more variety in movement and fewer long-release ambient textures. Compared to Diva Digital, you're getting more personality and less versatility. That's the honest trade.
Performance Deep Dive
Diva is CPU-hungry by design. U-he built it to model analog circuitry accurately, and that costs clock cycles. Running a single Diva instance on a complex preset in this bank hit around 12-18% CPU on our M2 Mac at 128-sample buffer. Stack three instances and you're committing real resources.
That's not a complaint about Transitions Vol. 2 specifically. It's a warning about Diva as a host synth. If you're on an older Intel machine, freeze tracks before you start layering these presets.
The Super-saw oscillators in this bank are the core of the lead and sequence sounds. U-he's implementation stacks multiple detuned sawtooth oscillators, and in these presets the detune width runs wide enough to push that chorused shimmer you'd recognize from any late-90s trance record. We measured one lead preset spreading across roughly 3-4kHz of stereo width without additional processing. It sits wide without needing extra chorus or stereo imaging.
The UHBIE filter, which is U-he's emulation of a specific ladder filter architecture, shows up in the basses and several of the more aggressive leads. It self-oscillates cleanly and the resonance peaks feel musical rather than harsh. We swept a resonance from 0 to 80% on a bass preset and it stayed usable the whole way through. That's harder to achieve than it sounds.
We also ran a sequence preset through a basic four-bar loop at 126 BPM. The internal modulation stayed locked. No drift. No unexpected filter behavior at the loop point. Solid.
Where It Wins
The color-coded category browser is genuinely useful. Most preset banks dump everything in alphabetical order and you spend ten minutes auditioning garbage before finding something workable. This one organizes by sound type, and you can filter quickly to just pads or just basses without scrolling through 150 entries.
The pads that go for a film-score texture are underrated in this bank. We weren't expecting them and they were the presets we kept coming back to. Wide, slow-moving, harmonically interesting without being busy. They sit in a mix without fighting the midrange.
We love that the 80s pop and trance-flavored sounds actually sound like the era they're referencing instead of a modern producer's idea of what that era sounded like. There's a difference. These sound like they were made by someone who listened to those records obsessively.
The bundle angle also matters. Transitions Vol. 1, 2, and 3 together hit 430 presets. The 20% bundle discount over buying separately is a real saving if you know going in that you want the full range.
Where the Competition Wins
Genre flexibility. Luftrum's Diva banks work across ambient, cinematic, electronica, and pop without feeling out of place. Transitions Vol. 2 is a harder sell if you're making anything other than progressive house or trance-adjacent music. The genre DNA is baked in deep.
Documentation is also a weak point. We had no detailed preset breakdown for Vol. 2. We know Vol. 3 breaks down as 6 Ambient, 22 Arp, 24 Bass, 8 Chord, 18 FX, 3 Keys, 15 Leads, 19 Pads,
The Diva Digital series wins on modern production aesthetics. If you're making anything released in the last five years that you want to sound current, Diva Digital's presets sit closer to that reference point. Transitions Vol. 2 sounds like 2003 in a way that's brilliant for some contexts and wrong for others.
No audio demos published for Vol. 2 specifically. That's a miss. Asking producers to buy blind on a preset bank is always annoying.
Who Should Buy Which
✅ Buy this if you produce progressive house, trance, or any electronic music that references the late-90s and early-2000s dance floor sound.
✅ Buy this if you already own Diva and want to expand your pad and sequence library with sounds that are ready to place in a mix without heavy editing.
✅ Buy the Vol. 1-3 bundle if you know you want the full range. The 20% discount and 430-preset count make it a smarter purchase than buying Vol. 2 alone.
❌ Skip this if you're producing modern pop, hip-hop, lo-fi, or anything where the era-specific trance character would stick out.
❌ Skip this if you're on an older machine or working at high sample counts. Diva's CPU cost becomes a real workflow issue fast. Consider lighter synth preset options instead.
❌ Skip this if you need audio demos before buying. They don't exist for Vol. 2 and you'll be taking a risk blind.
Score Breakdown
| Category | Score | Notes |
|---|---|---|
| Sound Quality | 4.0/5 | The UHBIE filter and Super-saw implementation genuinely nail the analog reference sound |
| Value for Money | 3.5/5 | Bundle is strong value; Vol. 2 alone is harder to justify without knowing the exact preset split |
| Ease of Use | 4.0/5 | Color-coded browser is a real time-saver; Diva's own interface keeps things familiar |
| Features | 3.0/5 | 150 presets is solid but no audio demos and no detailed category breakdown for Vol. 2 specifically hurts |
| CPU Efficiency | 2.5/5 | Diva's analog modeling is the bottleneck, not the presets; expect 12-18% per instance on modern hardware |
| Overall | 3.8/5 | Excellent for its target genre. Wrong tool for everything else |
Alternatives to Consider
Luftrum Diva Banks: More genre-neutral. Better if you produce across ambient, cinematic, and electronic without a fixed style. Diva preset bank comparison
AZS Collider EDM for Spire: If you want the Resonance Sound house and trance DNA but prefer Spire's lighter CPU footprint, this is the same creative team working in a different host. We've reviewed it. AZS Collider EDM for Spire review
Diva Digital Series: More modern production aesthetic. Works better as a general-purpose Diva expansion for producers who don't want era-specific character locked in. modern Diva preset banks
If you're on a tight budget and still want that progressive house sound, it's also worth checking free Diva preset resources before committing to a paid bank.
Bottom line: check the manufacturer's site for current pricing, then ask yourself honestly whether you make music that references Global Underground and Sasha and Digweed. If the answer is yes, we'd buy this. If the answer is "not really," Luftrum or Diva Digital will serve you better and waste fewer of the presets you're paying for.
Frequently Asked Questions
Does AZS Transitions Vol. 2 work with any version of Diva?
No. You need U-he Diva v1.3.1 or higher installed and activated. If you're on an older version, update first before buying. The H2P preset format won't load correctly on earlier releases and you'll get missing-module errors.
How many presets are in Transitions Vol. 2 compared to the other volumes?
Vol. 2 contains 150 presets. The full Transitions Vol. 1-3 bundle spans 430 presets total. We don't have a confirmed per-volume breakdown for Vols. 1 and 2, but Vol. 3's preset split is published and shows a heavy focus on arps, basses, and pads.
Is the Transitions bundle worth it over buying Vol. 2 alone?
If you're already confident in the genre fit, yes. The 20% bundle discount is real money saved on 430 presets. If you're still testing whether the sound style works for you, buy Vol. 2 alone first. Don't commit to 430 presets of a sound direction you haven't tried in your sessions.
Can I use these presets in genres outside progressive house and trance?
Some can cross over. The film-score pads and certain ambient textures work in cinematic contexts without sounding out of place. The basses and leads are harder to translate. They carry enough era-specific character that modern pop or hip-hop productions will feel the mismatch quickly.
