Review momentum
ⓘ How we measure thisReview momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.

KORG has answered the question: “Can a tuner recognize good sound?” With the KORG cortosia you'll see what's missing from “good sound” with just a glance. Even practice that's slightly boring (such as practicing the production of single notes) will become enjoyable. The cortosia is a completely new type of interactive tuner app designed to improve the overall quality of sound produced by the artist.
* Analyzes five elements of “good sound” and rates them in real time
* Automatically records “good sound” so you can check your daily improvement in technique
* Lets you compete against the world in “good sound” and vie for ranking
* Supports flute, clarinet, trumpet, violin, cello, saxophone, trombone and euphonium
Analyze five elements of “good sound” and rate them in real time:
Just what is “good sound”? Beautiful sound, pleasant sound, sound that resonates in the listener's heart. Perceptions of “good sound” differ between people, but could there be some commonalities? Through cooperative research with Pompeu Fabra University in Barcelona, Spain, under the direction of Professor Xavier Serra, Korg has arrived at a technology “Artistry” (*1) for evaluating “good sound” based on five elements.
1: Pitch Stability
2: Dynamic Stability
3: Timbre Stability
4: Timbre Richness
5: Attack Clarity
Simultaneously with the tuner display, a radar chart shows the results of analyzing these five elements in real time, and scores them on a scale of 100 points. While tuning, you can see at a glance what aspects of your tone are lacking. You can also listen to a model tone and hear how it differs from your own sound. This is highly recommended for beginners who have just started a musical instrument, as well as for intermediate players who want to advance to the next level.
*1: Automatic Rating Technology for musical InSTRument plaYers
Automatically record “good sound,” and check your daily advances in technique:
Data is automatically recorded and kept when tuning and scoring. You can audition the accumulated recording data or recall a radar chart for it, and you can also check the number of hours you practiced and your best score for each day. By looking at your past results, you can see how you are progressing. In addition, you can post your score to a social networking service such as Facebook or Twitter allowing you to record or upload your daily progress (or backsliding) as if you were writing a diary. Whether you use this to compete with your friends or to give encouraging comments, it's a great way to improve your skill while enjoyably sharing information.
