4Front TruePianos – Professional Virtual Piano Instrument

A Virtual Piano Designed for Musicians

4Front TruePianos is a virtual piano instrument designed around playability, responsiveness and realistic performance.

While many virtual pianos depend on extremely large sample libraries, TruePianos follows a different philosophy. The developer combines different technologies depending on what works best for each aspect of piano reproduction.

Sampling is used where samples provide the desired result, while other techniques are employed where a purely sample-based architecture would make the instrument less flexible.

The result is a virtual piano designed to respond naturally to the musician while maintaining relatively modest system requirements.

Five Piano Modules in One Instrument

The full version of TruePianos contains five piano modules.

Each module represents a different interpretation and tonal variation of a piano. Inside each module, multiple presets provide additional variations in character.

The architecture can therefore be understood as:

Piano Module → Multiple Presets → Individual Piano Character

Instead of identifying every module directly with a particular commercial acoustic piano model, the developer deliberately uses independent module names.

This allows the sound designers to creatively combine source material and processing without suggesting that a module is intended as an exact recreation of one particular physical piano.

Different Piano Characters

TruePianos has historically included recognizable module names such as:

• Amber
• Sapphire
• Diamond
• Emerald
• Atlantis

These modules provide different tonal starting points for different styles and playing techniques.

The variety allows TruePianos to work across solo piano performances as well as productions where the piano needs to fit inside a larger arrangement.

Designed for Real-Time Performance

Performance is one of the central priorities behind TruePianos.

The instrument was specifically optimized for real-time playing, where the response between pressing a MIDI keyboard key and hearing the piano is extremely important.

TruePianos is also designed to make efficient use of modern processors.

For advanced polyphony, processing can be distributed across multiple CPU cores.

This makes the instrument useful for musicians who want expressive piano performance without loading an enormous sample library into memory.

Sympathetic Resonance

One of the important realism features in TruePianos is Sympathetic Resonance.

On a real acoustic piano, strings do not behave completely independently. When certain notes are played or sustained, other strings can resonate sympathetically.

TruePianos includes an option designed to recreate this behavior.

Sympathetic Resonance can be enabled from the instrument’s options screen and contributes additional interaction between notes during expressive piano performances.

Increased Polyphony

TruePianos also provides an Increased Polyphony option.

Polyphony determines how many notes can continue sounding simultaneously.

This becomes particularly important when playing:

• Large chords
• Classical piano
• Sustain-pedal passages
• Fast arpeggios
• Romantic piano
• Cinematic piano
• Dense arrangements

The Increased Polyphony option provides additional headroom for demanding performances, although it also requires additional CPU resources.

Match TruePianos to Your MIDI Keyboard

A virtual piano can only feel natural when it responds correctly to the player’s keyboard.

TruePianos therefore includes dedicated controls for adjusting the relationship between MIDI velocity and the instrument’s dynamic response.

The advanced interface provides control over parameters including:

• Keyboard sensitivity
• Dynamic response
• Release time
• Tuning
• Volume

This means TruePianos can be adjusted to match different MIDI controllers and playing styles.

A player using a lightweight synth-action keyboard may require different sensitivity settings from someone using an 88-key weighted hammer-action controller.

Dynamic Piano Performance

TruePianos is designed to respond dynamically to MIDI performance rather than simply functioning as a static piano playback instrument.

Soft playing can produce a gentler response, while stronger velocity can bring out a brighter and more forceful character.

Fine-tuning the keyboard sensitivity is therefore an important part of configuring the instrument.

Once the response has been adjusted correctly, the settings can be saved as the default state.

Built-In Reverb

TruePianos includes built-in reverb for adding space and ambience to the piano.

This can be useful when playing the instrument standalone or when you want a complete piano sound without loading an additional reverb plugin.

For larger productions, TruePianos can also be combined with external studio effects inside your DAW.

Efficient Hybrid Technology

TruePianos does not describe itself as using only one sound-generation technology.

Instead, 4Front explains that different techniques are combined according to where each approach works best.

Where sampling provides the desired result, samples are used.

Where samples would reduce flexibility, other techniques can be employed.

This hybrid philosophy is one of the reasons TruePianos can provide realistic piano behavior without requiring the extremely large disk footprint associated with some modern multi-gigabyte piano libraries.

TruePianos 2.0

TruePianos is receiving a major modernization with the 2.0 generation.

On macOS, TruePianos 2.0 is officially available and introduces:

• Native Apple Silicon support
• Retina-display support
• VST3
• Audio Unit v3
• AAX
• Rewritten audio engine
• Improved performance
• macOS Tahoe support

For Windows, TruePianos 2.0 is currently available as a public beta and introduces:

• High-resolution display support
• VST3
• Native Windows ARM64 support
• Rewritten audio engine
• Significantly improved performance

The Windows 2.0 beta is backward compatible with TruePianos 1.x, although projects saved using 2.0 are not backward compatible with the 1.x version.

Apple Silicon Support

Modern Mac producers can run TruePianos natively on Apple Silicon.

The current Mac 2.0 release provides native Apple Silicon support instead of requiring the older Intel-only architecture.

This is particularly useful for musicians running current versions of:

• Logic Pro
• GarageBand
• Ableton Live
• Cubase
• Digital Performer
• Pro Tools
• Other compatible Mac hosts

Windows Support

TruePianos also continues to support modern Windows systems.

The developer currently lists:

Windows 7 or later, including Windows 11

The recommended configuration is Windows 10/11 64-bit with a 2.2 GHz or faster compatible processor and at least 512 MB of free RAM.

Lightweight System Requirements

One of TruePianos’ advantages is its relatively modest system footprint.

The developer’s current requirements list only 384 MB of free RAM as the minimum on both Windows and Mac, with 512 MB or more recommended for using the full feature set.

This makes TruePianos particularly interesting for:

• Live-performance laptops
• Older studio computers
• Large DAW projects
• Mobile production setups
• Producers who do not want huge piano libraries
• Systems with limited storage

Standalone Performance

TruePianos can also operate as a standalone instrument.

This means you do not necessarily need to open a full DAW simply to sit down and play piano.

Connect a MIDI keyboard, configure your audio device and use TruePianos as a dedicated software piano.

This can be particularly convenient for practice and live performance.

Great for Different Musical Styles

The different piano modules and presets allow TruePianos to cover a broad range of musical applications.

It can work well for:

• Pop
• Rock
• Jazz
• Classical
• Gospel
• R&B
• Ballads
• Cinematic music
• Songwriting
• Live performance
• Music education
• Piano practice
