Steinway D - pianosound to the highest perfection

The D-274 is the flagship model of world-renowned piano manufacturer Steinway & Sons. This beautifully hand-crafted instrument with its laminated wooden housing and its poured iron frame has not changed much since it was first developed at the end of the 19th century. With a length of 274 cm (almost 9 ft.) and a weight of almost 500 kg (1,100 lb.), the Steinway D-274 continues to play a significant role in the global music industry. An estimated 90% of all concert grands on the world’s stages are Steinway D-274 models, delighting its players and audiences alike.

The reasons are obvious: Especially when competing with orchestras, the D-274 impresses with its tremendous assertive sonic volume and power – which is not surprising considering its soundboard of almost two square meters (21.5 sq.ft.)!

Leading artists of all eras have appreciated playing a D-274, from Sergei Rachmaninoff, Vladimir Horowitz, Arthur Rubinstein, Glenn Gould, and Alfred Brendel to today’s top-notch pianists, such as Pierre-Laurent Aimard, Emanuel Ax, Hélène Grimaud, and Lang Lang, just to name a few.

SteinwayD Inst 1

Assertive, Ambient Sound

Our very own D-274 is a “Hamburg Model” and was hand picked from eight Steinway D models by Stefan Mendl, founding member and pianist of the Vienna Piano Trio. In a city rich with glorious instruments, it is ranked among the best sounding grand pianos in Vienna, and has been endorsed by all artists who have had the opportunity to play it. The instrument enjoys permanent, climate-controlled residency at Synchron Stage Vienna, which is characterized by its particularly warm, intense, and natural ambience. The hall has lent its acoustic signature to numerous international productions, from classical chamber music to international, large-scale orchestral film scores.

Sample Precision

To capture the D-274 concert grand with all its subtleties, our engineers developed a highly precise motion-control system based on a solenoid that controls a noise-free “robot finger”. The micro-controller moves the finger with super-human precision, providing flexible curvatures for down-strokes and release movements. The MIDI controlled system delivers more than 100 velocities and various release samples, depending on the preceding note length and various release speeds.

This innovation represents the pinnacle of our long-term sampling robotics development. An earlier version of the robot finger was used for sampling the Celeste found in our Synchron Percussion I Collection.

Customize Your Personal Sound

SteinwayD Inst 3In addition to the multitude of options from mixing various microphone signals, the D-274 concert grand comes with our free Vienna Synchron Pianos Software that offers multiple options for shaping your sound and the playing experience. Hosting a high-performance playback engine, the software provides a musician-friendly user interface that allows for quick and easy timbral control. Create your sound intuitively by filtering particular key ranges or even single keys, adjust the body resonance of the instrument or add just a pinch of algorithmic reverb to refine the overall sound.

I own the Ravenscroft, Hammersmith ,Steynway d galaxy garritan cfx academic grand , and i find this is the one that come closer to a real steinway , very evenly recorded , the pedal is the best it does sound like a piano with a lot of reverb added.Great for classic music and for some jazz too especially stride piano or lushy ballads that use a wide spectrum .A piano for a for a real pianist .It is easier to use the vst than to record a real steinway.You need a ssd external drive.
