The Best Just Got Better!

Once again, AAS raises the bar in the recreation of the classic electric pianos. Not only does Lounge Lizard EP-4 deliver the authentic tone of the originals, but it also preserves their action and feel. Once you get your hands on Lounge Lizard, that elusive electric piano sound becomes a vivid reality.

Using our award winning physical modeling technology, we've come up with refinements that take one of the most impressive and unanimously acclaimed software to another level.

New Features in Lounge Lizard EP-4:

NEW Factory Library

The completely renewed factory library features the classic electric piano sounds as well as over 200 gig- and mix-ready custom electric pianos making good use of the compressor, equalizer, and multi-effect processor.

NEW Compressor and Equalizer

These new additions are perfect to add punch and definition to your sound, letting you cut through any dense mix or stage.

NEW Character Control

The new Character control provides five classic studio and stage signal path emulations – that's the cabinet, pre-amp, microphone, and recorder chain that follows the piano's output – to easily snug fit your electric piano part into your track.

NEW Limiter

The new output limiter protects your ears and monitors during experimentation with the piano's physical modeling parameters while providing a maximum of distortion-free dynamics.

NEW Streamlined Interface

Redesigned from the ground up, the new interface now divides Lounge Lizard EP-4 into three panels: Play presents shortcuts to the main piano and effect parameters including bypass switches for quick edits; Edit lets you get under the hood and voice the piano to taste; while FX supplies equalizer, compressor, multi-effect, and reverb processors for final shaping duties.

NEW Bank and Program Manager

Lounge Lizard EP-4's new manager allows simple and efficient organization, backup, and sharing of your sounds.

UPDATED: Overhauled Effects

Reinvigorated, polished, and tuned especially for the electric piano, Lounge Lizard EP-4's multi-effect processor features our best sounding chorus, delay, phaser, flanger, distortion, notch filter, wah-wah, auto-wah, and reverb to date!

NEW Native 64-­bit Audio Unit (AU) and VST Plug­-Ins

Lounge Lizard EP-4 now runs in native 64-bit on Mac OS X and Windows making it compatible with the latest sequencers.

Presets and Effects

Lounge Lizard comes with an extensive preset library that is simply inspiring, giving you access to electric piano sounds popularized by musical legends like Chick Corea, Herbie Hancock, Stevie Wonder, and George Duke. There is a choice of pure and true tones as well as a selection of processed ones courtesy of the high-end effects section. The original pianos provided timbre and volume adjustments by letting you position the tines in relation to the pickups.

The effects section includes the classic tremolo, chorus, wah, and phaser effects as well as EQ, delay and reverb. These effects are specially designed for the electric piano, making it very easy to create your own distinctive custom tones.

EP Character and Beyond

The original Rhodes™ pianos provided timbre and volume adjustments by letting you position the tines in relation to the pickups. These adjustments were at the heart of the electric piano's character as they controlled the harmonic content, attack, and decay of the sound, offering unique tone to each player. But there was a price for this flexibility. Several painstaking hours with a screwdriver and incredible patience was needed to change the sound of an electric piano.

Suffer no more! With Lounge Lizard, the preset library provides a selection of thoroughly chosen Tine/Pickup configurations. You also have the ability to make those adjustments in real time via two simple controls: Distance and Symmetry.

Tine Pickup

It doesn't end there. Because controls are provided for the various electro­mechanical components, Lounge Lizard can be pushed far beyond hardware equivalents, opening up a completely new realm of sonic possibilities!

What's more, since the interaction between the tine and pickup is quite unique, its effect can't be obtained with the filtering provided by samplers. This limits sampled solutions to one or two fixed configurations and brings physical modeling to the forefront of the electric piano recreation.

Modeling an Electric Piano: How it works

The electric piano was invented by Harold Rhodes (1910-2000) during the forties when he was in the army. The first instruments he built were made of aircraft pieces and were intended to entertain army servicemen. It became a very popular instrument in jazz and rock, and has enjoyed a resurgence in recent years through it's extensive use by the world's top hip hop, R&B, and house producers.

The mechanism of the electric piano is, in fact, quite simple. A note played on the keyboard activates a hammer that hits a fork. The sound of that fork is then amplified by a magnetic coil pickup and sent to the output, very much like an electric guitar.

Jason Buchwald, musicplayers.com
“Lounge Lizard hits a home run in all departments: EP-4 sounds great, and scores high marks for ease of use and overall versatility. If you need a Rhodes or Wurli in your setup and you make use of soft synths in your rig, you just can't go wrong here.”


Ted Perlman, producer, arranger, guitarist, composer, engineer
“Lounge Lizard EP-4 is the best electric piano I own! I actually have a real wooden Wurlitzer, and Lounge Lizard sounds soooo close, it's scary. Nothing else is even close!”


Myron McKinley, musical director for Earth, Wind & Fire
“Lounge Lizard EP-4 gives you so many options to really bring uniqueness to your sounds and performance, it is a necessary piece in my setup.”


Morris Hayes, keyboardist for Prince
“The Lounge Lizard EP-4 is my go-to plug-in for the Rhodes and Wurlitzer flava I need on stage in my Open Labs Neko and Miko virtual instrument players. Lounge Lizard EP-4's interface is very simple yet involved enough to really tweak the sound to perfection. This plug is smoove man!”


Francis Preve, Keyboard
“As a Logic user, I've been relying on its included plug-in, EVP88, for my electric pianos in recent years. But after some time with Lounge Lizard, I'm beginning to have second thoughts. There's something about the texture of this plug-in that's a bit warmer and more organic—to say nothing of its overall flexibility—that makes it an excellent alternative or addition to the competition. Of course, EVP88 works only with Logic, so if you use any other DAW and want killer classic electric piano sounds, Lounge Lizard EP-4 is a no-brainer that you really owe it to yourself to check out.”


Jason Scott Alexander, Remix
“All in all, Lounge Lizard 3 is as good as it gets, and the overhauled preset library demonstrates its inspiring potency. The best sounding Rhodes and Wurlitzer models on earth just got even better.”


Len Sasso, Electronic Musician
“Lounge Lizard EP-4 is equally at home in the studio and on the gig. It is CPU efficient and runs well on a reasonably fast laptop. It offers far greater programmability then sample-based electric pianos, and there are no streaming or RAM issues. If you're looking for a virtual electric piano, this is the one.”


Joe Silva, Music Tech
“With improved modelling and increased flexibility in sound shaping, you can be assured that the EP-4's sound is nothing short of gorgeous. A clear winner. If theses are the sorts of sounds you're after, there's not excuse not to have the EP-4 as part of your virtual instrument arsenal.”


Martin Walker, Sound On Sound
“If you like electric piano sounds and have a computer, you have to buy Lounge Lizard—it's as simple as that!”


Computer Music
“If you're a lover of electric piano sounds, Lounge Lizard remains a must-have. In fact, we reckon it's still one of the finest VST's you can buy.”


Nick Peck, Electronic Musician
“Applied Acoustics has developed a wonderfully realistic Rhodes emulation with EP-2. Right out of the box, it offers plenty of parameters to tweak, good effects, and lots of great-sounding factory patches. If you want to add a Rhodes to your recording rig without the hassle and maintenance of the real thing, Lounge Lizard is worth a serious listen.”


David Leishman, Macworld
“The real fun lies in programming the piano's 'physical' characteristics.”


John McJunkin, Remix
“If you want an electric piano, this is the only product you need. You not only save the weight and bulk of the genuine article but also gain controls and abilities that supersede real electric pianos. In addition to brilliant electric-piano emulation, you also get some nice effects right in the same package, not to mention the ability to snapshot that perfect tone you tweaked until 3 in the morning. The parametric controls yield a panoply of tones, from clean and bright for ballads to filthy and raunchy for blues to phasey and filtered for funk. If you're touring, you'll thank Applied Acoustics for this gift from heaven. But even if you're not, this instrument will inspire you to do things you didn't know you could.”


Joerg Sunderkoetter, Keyboards
“A better sounding and more flexible E-Piano simulation is not provided by any other virtual instrument”
“If you ask me if I prefer Emagics EVP88 or Lounge Lizard, I would clearly vote for the later one.”


Joe Silva, Music Tech
“Connoisseur of the real thing may also stop to ponder the advantages of using Lounge Lizard over their temperamental space-consuming instruments, particularly for practising at home.”


Chuck Piers, Future Music
“The finest software electric piano emulation to date, simple as that. It even looks vintage too!”


Alexander Schmidt, Keys
“Wer authentische E-Pianos, aber auch abgefahrene Klänge sucht, der sollte den Lounge Lizard 2 unbedingt antesten, (...).”


Sam Inglis, Sound On Sound
“Lounge Lizard was already more verstile than any piano emulation had any right to be (...).”
“If you don't already own it (Lounge Lizard), version 2 provides yet more reasons to give in to temptation...”


Michael Cooper, Mix
“Beyond providing convincing emulations of vintage keyboards of yesteryear, its plethora of wide-ranging controls allows you to create hybrid instruments and even startling synth tones that venture beyond piano bars and soul trains. With a $199 list, Lounge Lizard is more than a class act, it's a bargain.”


Craig Anderton, Eq
“(...) this is the plug-in to beat. (...) given the outstanding quality and flexibility of the emulation, it's no wonder Keyboard magazine gave it a KeyBuy award.”


Scot Solida, Grooves
“The interface is a thing of beauty (...). It feels like a living, breathing machine and inspires hours of jamming (...) the Lounge Lizard is a must.”


Future Music
“At this price Lounge Lizard is difficult to fault and should be up there on the old shopping list representing one of the best buys out there. A soon-to-be-realised classic.”


Francis Preeve, Keyboard
“In the context of a mix, the Lizard sounded terrific: organic, punchy, and very playable. Having effects built into the modeling engine made setting up the overall sound of each patch a breeze (...). It is quite the little beast.”


Thaddeus Herrmann, De:Bug
“Hier kommt ein klarer Gewinner nach Punkten (...). Der Lounge Lizard klingt Killer!”


Kevin Young, Canadian Musician
“You may want to load this software when you have a fair amount of time because once you start to play around with it you may find it difficult to stop. Smart, sexy, and powerful, the Lounge Lizard EP1 is indispensible for anyone with even a passing interest in vintage keys sounds.”


Sam Inglis, Sound On Sound
“Lounge Lizard is one of the most impressive virtual instruments I've seen to date (...) it's a uniquely adaptable piece of virtual kit. It also represents excellent value for the money.”


Paul Sellars, MacUser
“VERDICT: One of the most impressive, best-sounding virtual instruments we've come across.”


Cliff Douse, Mac Format
“Which ever way you look at it, the Lounge Lizard represents better value for money than either of its competitors. It's a funky little number that will soon find its way into many computer music studios.”


Computer Music
“We found Lounge Lizard to be an inspiring, playable, flexible instrument that you can really work hard. As such—and at this price—It's an excellent buy.”


Computer Music
“It's when you pump the Lounge Lizard hard and dirty the thing up that you get the best results (...). As well as coming up with filthy tones that retro funksters will love, we managed to create plenty of sounds that bore little or no audible resemblance to those that would be produced by a 'traditional' electric piano, so there's no denying that AAS have produced a versatile instrument. (Lounge Lizard) does offer something genuinely different at a very competitive price. It may have a slick name, but this bad boy can be funky as the devil.”
