STJ Yamaha Personal Studio for Silent Brass

There were three major upgrades to the unit. The first two are associated with what Yamaha calls Brass Resonance Modeling™ Ver.2.0

  1. Greater control over reverb. Yamaha has brought back one of the original features found in the first Silent Brass ST7 module, reverb. You can now once again hear yourself as if you were in a large hall or just in a room.

  3. You now have the ability to hear in your ears what the audience is hearing instead of just from your vantage point. When you perform and practice, you hear yourself from the mouthpiece side of the instrument. Now, when you play, you can imagine yourself sitting out in front of the audience and listening to your performance. Very interesting concept and approach for a practice mute!

  5. You can record the music directly from your Silent Brass™ mute. With the provided Micro-B to USB-A cable, you can connect directly to a desktop or laptop computer and record your performance! With an adapter (not provided), you can also connect directly to your phone or tablet.

Yamaha has a free app named Rec'n'Share, available for Apple and Android. With this app, you can record video or sound of your performance as you play along. You can easily share that recording over the internet and social media. You can also analyze and change the original tempo and add a click sound to the song for ease in practicing. You can use the AB repeat function to playback a specific range of the song.

To use the Rec'n'Share app, you will need an additional adapter, or read below.

HOWEVER, there is an alternative that we have created to make the use of this app easier. Instead of buying additional adapters, we have an adapter that can be used on either Apple or Android.
The cost for this adatper is only
$10.00 more with the purchase of any Silent Brass™ product. Or $14.95 by itself.

Player Mode

Brass Resonance Modeling™ is original Yamaha technology that effectively cancels the characteristic closed sound of a mute, reproducing the open, natural sound of the unmuted instrument. This reduces stress on players by allowing them to practice and play freely without feeling restricted by the mute. 

 Brass Resonance Modeling utilizes three simultaneous processes to produce the realistic tone of the brass instrument

1. Cancel the distinctive mute sound

Sound picked up by the microphone at the end of the pickup mute is processed digitally to cancel out the characteristic “closed” sound of the mute.


2. Add the instrument’s natural sound

The natural sound that emanates from the bell and returns to the player’s ears when the instrument is played without a mute is reproduced and added.



3. Adjust left-right balance to match the player’s position

The timing, volume, and tone of the sound reaching the player’s left and right ears are individually adjusted, and reverb is added as needed to accurately simulate the feel of playing in a room or hall.



Aux In Jack

This jack allows an external sound source to be combined with the signal coming from the mute, such as an MP3 player, Tablet, Cell phone or CD Player. You can then play along with your favorite song in practice and performance settings, putting the fun back in your practice sessions.


Mute In Jack - The mute "input" jack allows a quick and easy connection to any of the 6 new Silent Brass Mutes. Phones Jack - The headphone "output" jack allows the Silent Brass system to be connected to earphones for private practice, an external sound system for sound reproduction, or to a recording system for public performance and recording. Contols - Microphone Volume and a Main Volume control, Reverb dial, PLY/AUD (Player or Audience), Room/Hall, ON/OFF
Power Supply - AA alkaline or nickel-metal hydride batteries x 2 (3V DC)
