The Silent-System retrofit kit for upright and grand pianos

Developed by Andreas Dütz (25 years of experience in developing silent systems for pianos) and a team of experts in Japan and Europe, adsilent is the best you can get on the market for retrofitting silent systems for upright and grand pianos.

With   adsilent 2   there are a lot of possibilities

Excellent piano sounds with 9+ sample layers and 128 dynamic levels, recorded by european specialists. 100% touchless key and pedal sensors. Key sensors that are unparalleled in their space requirements and high precision. Modern features like USB-C, integrated Bluetooth MIDI** and wireless remote control via app make it really unique.

At home

Use the adsilent system at home during the day or at night. As a result your housemates and neighbours can calmly pursue their hobbies.

Record & Play

Record part of a four-hand piece. While playing your recording – play along – that way you can practice four-hand pieces, also when your partner isn’t available. Or, you want to record your performance and send it to your friends, relatives or teachers or you want to further process it digitally? This is all possible with the adsilent! Record MIDI data and use it directly with the adsilent 2 app*. Connect adsilent directly via cable to your computer or stereo system to record your performance in audio format.

Ideal for learning

Watch your teacher via YouTube or video conference on the tablet. The sound from the teacher is sent into the adsilent 2 via LINE IN. In the headphones you hear your piano playing and the lesson from the teacher. Several students can practice at the same time at the music school. Students can listen to the played exercises via headphones. The piano teacher can plug in a second headphone and listen to his student at any time.

Smartphone-App

adsilent offers different control possibilities. You can operate it by pressing a button at the piano or directly from your mobile phone via Bluetooth**. (Apple iOS and Androids apps are available for free)

Combine with a player system

adsilent can also be added to a player system as a recording system. This combination, will enable you to record your piano performance and play it back live on your player system (e.g. PianoDisc iQ / PRODIGY).

The best features of adsilent 2

  • Silent-System available for installation in upright and grand pianos
  • As an option adsilent for upright pianos is now also available with our very robust steel mute rail. This mute rail is a bit more costly and requires more installation time but it enables the installation of silent technology in some pianos that could not be installed without it. In addition, it offers the ambitious pianist the opportunity to keep the change in the regulation of the piano action as small as possible.
  • Next Generation Let-Off Expansion System (= LES system). adsilent is optionally available for acoustic grand pianos with LES system. This additional system adapts the mechanical regulation for use with the mute rail, only when the mute rail is activated. In normal operation, your grand piano remains completely unchanged - as if it had no silent system.
