Motus does not really have an equivalent on the market in terms of acoustic realism and variety of pianos and harpsichord available, it is obviously on these two instruments that we put all our energy to give the illusion almost total to play in acoustic mode, we have for example integrated the natural phenomenon of resonance of the strings by sympathy, as well as the effect of global resonance of the damper pedal.


The first two pianos are modern Steinway D sampled with the utmost care. One is clearer, the other is rounder ...


Remarkable sampling by an American Steinway piano studio by Glenn Gould currently at the National Arts Center in Ottawa. We will recognize the exceptional clarity typical of the American Steinway's timbre of this period, as well as the typical and very brilliant harmonization demanded by the legendary pianist ...



For lovers of historical sounds, we sampled a concert Pleyel from the time of Chopin! There is of course a world between it and the beautiful bank Steinway, but the experiment will take you back in time hearing a sound of time ...



The Motus silencer has unique function on the market, your piano can be transformed into a high-end virtual organ thanks to the magnificent audio sampling work carried out on a real church organ made in Germany in the late 90s. You use the registration sheet placed on your desk and activate the 26 registers at your leisure, choosing the couplings to your taste, and this as on an authentic organ following registration below:

1-Prestant 8'

2-Prestant 16'

3-Flūte douce 8'

4-Quinte 8'

5-Trompette 8'

6-Trompette 16'

7-Bourdon 16'

8-Cor de nuit 8'

9-Geigenprincipal 4'

10-Flūte traversičre 4'

11-Hautbois 8'

12-Trompette harmonique 8'

13-Clairon 4'


14-Chamades 8'

15-Basson 16'

16-Cor anglais 8 '

17-Cromorne 8'

18-Voix humaine 8'

22-Flūte fuseau 4'

26-Plein jeu



The sampled instrument is a real baroque harpsichord, Nicolas Blanchet 1723, on 5 octaves just like the original. You operate the registers with the 3 white bass keys of your piano keyboard according to the registration sheet. 8' lower keyboard, 8' upper keyboard with a softer sound and finally 4' octave playing. You can couple these 3 registers independently like a real harpsichord.



This new NUMACOUSTIC option intended exclusively for the MOTUS silencer is fantastic. This concept consists of placing vibrators on the back of the piano top, the idea being to replace the vibration of the string, it is therefore the soundboard that emits the acoustic wave, it is therefore in the end of a natural instrumental sound. The first advantage of this system is to be able to adjust the volume lower than the acoustic sound of the instrument, and therefore to avoid the systematic use of headphones when absolute silence is not essential. It also considerably increases the capabilities of your piano, since its soundboard is capable of transmitting sounds other than the piano with breathtaking realism.

The "touch" of your piano is perfectly preserved

To make your piano quiet, it is necessary to stop the hammer 4 mm before it strikes the rope, this is achieved thanks to a perfectly rigid blocker operated by the central pedal, as you can see in the picture below. against. The "touch" of the piano is much better in this case than when using a conventional mute, as the blocker returns the hammer with the same elasticity as a string, the great defect of an ordinary mute is in shock effect, this feeling is very unpleasant for the pianist. Our 100% optical sensors without lever or spring have no impact on the touch of your piano.
