Latest generation technology using optical reflection !

Our new ultra flats opticals sensors 3.5mm only are  like a revolution for silent systems installers, easy and quick to install, they allow installation on all types of pianos. Most adaptable silent systems on the market are equipped with old generation sensors, it is a mechanical levers and springs under the keyboard, unreliable over time and very imprecise because the lever is not attached to the key and causes "misfire" at high speed repetition, in addition, the spring of the lever increases the key weight, this problem persists even when you play your piano in acoustic mode, since the mechanical spring is placed permanently under your keyboard.

One only technology is reliable to date, this is technology with 100% non-contact optical sensors that we use on our Motus silencer and this one is found on major Japanese brands in factory installation. No leverage, no spring, the reflective sensors analyze with great accuracy the speed of the keys to calculate the dynamic, without any physical contact with the key.

Of course we favored when allocating memory the sound of the grand piano is a Steinway D concert grand piano sampled with great care, but we have also focused on other important instruments, the sound of panpipes is such an amazing realism that joined the flutist of breath attack.

The "feel" of your piano is perfectly preserved

To make your silent piano, it is necessary to stop the hammer 4 mm before it strikes the string, this is achieved thanks to a perfectly rigid blocker operated by the center pedal as you can see in the picture below against. The "touch" of your  piano is much better in this case than when using a traditional mute, since the stopper returns the hammer with the same elasticity than a string. Our 100% optical sensors without lever or spring have therefore strictly no impact on the feel of your piano.
