UVI released Twin 88 Keys on November 10, 2026. It's a single virtual instrument that puts a concert grand and a vintage electric piano under one set of keys. The point goes beyond two good pianos. UVI built them to play together, so the blend between them becomes a sound of its own.
At a glance: Twin 88 Keys is a sampled dual-piano instrument for macOS and Windows. It runs in the free UVI Player 5.0.2 or in Falcon 27.0.2, in VST3, AU, AAX, and standalone. The library is 11,889 samples and 121 presets, compressed to a 3.9 GB download. It costs 49 dollars or 49 euros at an intro price through November 22, 2026, then 99 dollars or 99 euros, and it's also part of UVI's SonicPass subscription.
What is UVI Twin 88 Keys?
Twin 88 Keys is built from two pianos you already know by heart. One is a full-size concert grand. The other is a vintage 88-key electric piano. UVI recorded each one deeply, then wired them into a single playable instrument with controls that let you move between them or stack them.
Most piano libraries give you one instrument at a time. You load a grand, or you load an electric, and you layer them yourself across tracks if you want both. Twin 88 Keys treats the pair as the point. You decide how the grand and the electric share the keyboard, and the blend becomes the sound. That focus on the space between two familiar instruments is what sets it apart from a standard piano library.
It sits in UVI's soundware catalog alongside instruments like UVI Synth Anthology 5 and the UVI Rumble bass synth. Like those, it runs inside UVI's own engine rather than as a standalone plugin.
The two pianos
The grand is a CFX model recorded in California with high-end studio gear. UVI describes a deep, resonant bass, a clear and singing treble, and the long, evolving sustain of a full concert instrument. It responds in fine grades to how hard you play. Three microphone positions, close, cinematic, and mono, let you decide how near the piano sits and how much room it brings into the mix.
The electric is a vintage 88-key model, sampled in Paris on every key at multiple velocities. Its tines ring warm and bell-like under a light touch, and they bark when you dig in. You can blend its direct signals with a microphone, moving between the clean focus of the DI sound and the open air of the mic.
Both instruments were captured across their full dynamic range. The small sounds that make a real piano feel alive are in there too. Pedal noise, release noise, the grand's sympathetic resonance, and key-off sounds each have their own level, so you can dial in realism or pull it back.
How Twin 88 Keys blends the two
The blending controls are the heart of the instrument. Split the pianos by range, and one carries the bass while the other sings above it. Blend by velocity, and the grand turns electric as you play harder. A tone blend darkens one piano so the other steps forward. Or turn a single knob from pure grand to pure electric and stop anywhere in between.
Each piano then has its own editing chain, which means separate microphones, filters, EQ, envelope, and modulation per instrument. Add a slow tremolo to the electric while the grand stays still. A gentle pitch drift brings age and character. You can also animate notes across the stereo field, and a motion arpeggiator sits on top for rhythmic patterns. None of this is required, since the 121 presets give you playable starting points, but the depth is there when you want to design your own hybrid.

Twin 88 Keys vs Addictive Keys
For sampled keys, Addictive Keys from XLN Audio is the obvious comparison. Both aim at producers who want ready-to-play acoustic and electric keyboards rather than a blank sampler. They take different routes to get there.
| UVI Twin 88 Keys | XLN Audio Addictive Keys | |
|---|---|---|
| Concept | Two pianos blended on one keyboard | Four separate keyboard instruments |
| Instruments | 1 concert grand plus 1 electric piano | Studio Grand, Modern Upright, Electric Grand, Mark One |
| Blending | Built in, by range, velocity, or tone | Load one instrument at a time |
| Engine | UVI Player (free) or Falcon | Standalone or plugin, own engine |
| Formats | VST3, AU, AAX, standalone | VST, AU, AAX, standalone |
| Price | 99 USD regular, 49 USD intro | 99 USD per instrument, 249 USD for all four |
The two tools solve different problems. Addictive Keys gives you four distinct keyboards, including an upright and two grands, and its ExploreMaps browser is a fast way to audition presets. You pick one at a time. Twin 88 Keys gives you a smaller menu, one grand and one electric, but it's designed around playing them together and shaping the blend. If you want a library of separate pianos, Addictive Keys is the broader kit. Twin 88 Keys is the better call when you want a single hybrid voice that moves between strings and tines.
Who Twin 88 Keys is for
This instrument fits the songwriter chasing a piano with a voice of its own, and the producer who needs keys that stand apart in a busy mix. If you already blend an acoustic and an electric piano by hand across two tracks, Twin 88 Keys folds that workflow into one patch with proper per-piano control. Existing UVI and Falcon users will find it slots straight into their setup and licensing.
It's a weaker fit if you only need a single clean grand or a stock electric for occasional parts. A free piano or a stock DAW instrument may cover that. It's also not the pick if you want a wide set of separate pianos, including uprights and multiple grands, since Twin 88 Keys is deliberately just two instruments. And because it runs in UVI Player or Falcon, you'll need that engine installed, a small extra step next to a self-contained plugin.
How much does UVI Twin 88 Keys cost?
Twin 88 Keys launched at an intro price of 49 dollars or 49 euros, running through November 22, 2026. After that it returns to 99 dollars or 99 euros. It's also included in UVI's SonicPass subscription, so SonicPass members can use it without a separate purchase. The download is 3.9 GB thanks to FLAC lossless encoding, and the instrument authorizes through a free iLok account across up to three machines.

Do I need UVI Falcon to use Twin 88 Keys?
No. Twin 88 Keys runs in the free UVI Player version 5.0.2, as well as in Falcon version 27.0.2. Both support VST3, AU, AAX, and standalone use on macOS and Windows, and the instrument needs a free iLok account for authorization.
How much does UVI Twin 88 Keys cost?
UVI lists an intro price of 49 dollars or 49 euros through November 22, 2026, then a regular price of 99 dollars or 99 euros. It's also part of the SonicPass subscription, so members don't pay separately.
Twin 88 Keys vs Addictive Keys, which should I pick?
Pick Twin 88 Keys if you want one grand and one electric designed to blend into a single hybrid tone. Pick Addictive Keys if you want four separate instruments, including an upright and a second grand, to load one at a time.
What are the system requirements?
Twin 88 Keys runs on macOS 10.14 through macOS 27 and Windows 10 to 11 in 64-bit. It needs 4 GB of RAM, a 3.9 GB download, UVI Player 5.0.2 or Falcon 27.0.2, and a free iLok account.
The verdict
This is a first look based on UVI's official materials, not a hands-on review. On paper, Twin 88 Keys reads as a focused, clever idea rather than another big piano pack. The recording pedigree looks strong, with a CFX grand captured in California and a vintage electric sampled in Paris, both across their full dynamic range. The blend controls, by range, velocity, and tone, are the real draw, and the per-piano editing gives you room to shape a hybrid of your own. At 49 dollars during the intro window, it's an easy instrument to recommend trying, especially if you already live in UVI Player or Falcon. Just go in knowing it's two pianos built to play as one, not a broad library of separate keyboards.
