Every song needs a foundation.

Pianos and keys provide the harmonic bed for your track. You need instruments that feel alive under your fingers. We tested the Best Piano VSTs and Keyboard Libraries to find the ones with soul.

The Criteria

We look for connection and nuance:

  • Resonance: Do the strings vibrate sympathetically when the pedal is down?
  • Velocity Curve: Is there a smooth gradient from soft to loud?
  • Character: Does it sound like a sterile recording, or a living instrument?

Our curated lists below cover the essentials.

Frequently Asked Questions

Weighted vs. Synth action?

Weighted keys simulate the hammers of a real piano, essential for expressive playing. Synth action is lighter and faster, better for organ slides and rapid lead lines.

Physical Modeling vs. Sampling?

Sampling plays back recordings of a real instrument (realistic but static). Physical modeling calculates the sound in real-time (expressive and organic but CPU intensive).

What is 'Prepared Piano'?

A technique where objects (screws, felt, rubber) are placed on or between the strings to alter the timbre. It creates percussive, otherworldly, and avant-garde textures.

Layering pianos?

Try layering a dark, cinematic felt piano with a bright attack (like a mallet or harp) to create a unique composite sound that cuts through a mix while staying warm.

Pedal noise?

Mechanical noises add realism. Good libraries let you control the volume of pedal stomps, key releases, and seat creaks to place the listener in the room.

Electric piano types?

Rhodes is warm and bell-like. Wurlitzer is grittier and more bitey. Clavinet is percussive and funky. Know which one fits the vibe of your song.
