Ultimate Avant-Garde Piano

The Ultimate Avant-Garde Piano

The ultimate virtual prepared piano experience, brought to you by UVI and the renowned IRCAM acoustic research center in Paris. 

We brought together the world’s finest engineers and equipment to comprehensively multi-sample 45 preparations at IRCAM Labs on a Yamaha C7 Grand Piano. 

The result is the most flexible and exquisite sounding prepared piano instrument on the market. Freely customize your instrument with up to two preparations per note, mix multiple mic positions and quickly explore new sonic landscapes with the randomizer. Try the included preparations or make your own in minutes! 

Truly the most advanced, flexible, and comprehensive prepared piano instrument ever made, IRCAM Prepared Piano leverages the power of the UVI Engine in ways never before seen.


Sustain and None 

A normal piano sound. The strings are struck by hammers, triggered by the notes played on the keyboard. Use of the una corda and forte pedals is possible. There is no object in or on the strings modifying the sound.

The none preparation setting does not refer to there being no object or preparation modifying the sound of the string, but rather to the lack of sound produced by playing this key –  a form of preparation that is impossible without breaking the hammer.

This setting can be very useful in preventing the sounding of misplayed notes, or for playing Gyorgy Ligeti’s Etude: Touches bloquées (by cheating, a little…)


Striking the Strings

Mallets : The strings are struck with a vibraphone mallet. The resulting sound is similar to a normal key strike, but is slightly softer due differences between the mallet and the normal hammer action.

Wooden Stick : The strings are struck directly using wooden sticks. The attack is harder and shorter. The timbre is similar to that of a dulcimer, and can be activated by pressure on the forte pedal.

Stick Rebound : This setting features the same technique and resulting timbre as the Wooden Stick setting, but allows the stick to bounce on the string after the initial strike.

Muted Stick Rebound : This setting features the same technique as Stick Rebound, but uses the stick on muted strings (see mutes).

Plucking or Strumming the Strings with the Fingers

Pizz. : The strings are plucked with a plectrum, one string only per note. This results in a sound resembling that of a guitar. It is a widely used effect, for example by Georg Crumb in Makrokosmos, or by Gerard Pesson in Rescousse.

Scratch : A fast scraping action by the nail along the string. When used on the bass strings, this causes a burst of harmonics. One can hear this technique, in combination with numerous other piano string effects, in Clepsydre by Horacio Radulescu (for 16 sound icons, or pianos installed vertically and played exclusively on the strings).

Sustained Sounds

Bow : Rosin horsehair (a single strand of a violin bow) causing the two or three strings that comprise a single pitch to vibrate. The resulting sound is continuous. Changes in the direction of the bow are always audible and give transient color to the timbre. This effect is sometimes made with fishing line rosin.

Ebow : A small device normally used on electric guitars, causing the strings of the piano to vibrate through a magnetic field. This produces a continuous sound with a masked attack, resulting in a delicate and subtle timbre.
