Improved Sound

The sound from this "3rd generation" system has been greatly improved over the previous generations, by using the process called Brass Resonance Modeling. This utilizes three simultaneous processes to produce the realistic tone of the brass instrument. This unique technology by Yamaha uses the modeling of non-muted brass instruments to correct your instrument's tone when the Pickup Mute is in place. With a combination of The Personal Studio and a Pickup Mute, the resulting sound is so realistic, it's hard to tell whether the instrument is muted, or not.

1. Eliminate the “Mute” Sound

Digital processing applied to the sound received by the mute’s
microphone effectively cancels the sonic characteristics of the mute.


2. Add Ambience

Another digital process brings back the natural sound of the un-muted instrument, and adds the characteristics of the acoustic environment through which the sound travels before returning to the player’s ears, making it sound as if you are playing without a mute at all.


3. Adjust Left/Right Balance

Digitally simulating how the sound returns to your ears—adjusting for the slight differences in volume, timbre, and delay between your left and right ears—and adding reverb constructs a virtual sound scape that makes it sound like you are playing in a large room or concert hall.
