## What is Extrack?

Play along with your favorite tracks.
Extrack, an app that lets you split instruments and analyze chords, instantly.
-You can use the basic features for free with no time limit. Subscribe, and you can unlock more advanced features.

 ・Separate songs into different instrument parts (vocal, guitar, piano, bass, drums, wind instruments) and freely adjust their volumes.
 ・Practice "minus one" style (mute one part and play it yourself).
 ・See the chords and how to play them on guitar or piano in real time while the song plays.
 ・Change the tempo, keys, or repeat specific sections easily. The app is very easy to use, even for beginners.

 ■When you feel like jamming with a band!
-Load any song from your smartphone or tablet, and Extrack automatically separates it into each instrument part — such as guitar, drums, bass, piano, and wind instruments like saxophone. You can adjust the volume of each part freely, just the way you like.
-If you’re a guitarist, turn down the other instruments and focus on the guitar sound to pick up even the most subtle phrase by ear. Then, switch the mix up, mute the guitar part and jam along with the rest of the band. It’s the closest thing to being on stage with your favorite artists! Want to tighten your rhythm? Turn up the drums and bass for focused practice. Or mute the vocals and enjoy singing along karaoke-style with real band sound!

■When you feel like jamming to that song you love!
-Extrack automatically analyzes and displays the chord progression of any song. Even if you’re not good at figuring out chords by ear, you can enjoy jamming while watching the chords in real time.
-It also shows how to play each chord on guitar or piano visually so even beginners who can’t read sheet music can feel confident.
-Just load a song, and you can start practicing right away! If the song has chords that are too difficult, simply change the key or set a capo to make them easier to play.

■When you’re stuck on a part you’re having trouble with.
-Want to play just one phrase over and over?
-Want to slow down the tempo and practice carefully?
-With Extrack, you can do it all easily. Simply select the section you want to repeat, skip by measure, or adjust the playback speed to match your pace. Plus, Extrack comes with a built-in metronome that automatically syncs with the song’s tempo, perfect for training your timing and rhythm.

■Just load your favorite song, and enjoy practicing with all of Extrack’s features.
-Works with : MP3, AAC, FLAC, and more.
-Add songs from iTunes or your CDs and start playing!

### 4/5 — 時々再生できなくなる

*2026-08-18*

分離精度はなかなか。
機械的な分離にしては、しっかり分離してくれるので耳コピが捗ります。
ただ、分離後にしばらく再生せずにいると、高い確率で再生ができなくなる（一瞬だけ音が鳴って止まる）のが困りもの。
しかもアプリ再起動しても治らず、しばらくすると再生できるようになるので、ユーザー側で対処できない。
それ以外は、今のところ満足しています。

### 1/5 — 課金内容を書いとけよぉ

*2026-08-11*

ドラム、ベース以外は課金です。
しかも月5曲から課金です

制限解除は年額9000円または月額900円

そして曲はiTunesからダウンロードなのでappleミュージックでサブスク支払ってても、別途曲を購入です。

1曲255円です。

1曲買ってから、ギターは課金と知りました。

買うまで知る術はありませんでした。

そして、その1曲のために年額か月額の2択のサブスクです。

この曲のギターを100円で制限解除とかならまだしも…

課金しなきゃ使えない機能は書くべきですよ。

最初から書いてあったら、気持ちよく使えたの…

YAMAHAがこんな小銭稼ぎの詐欺まがいなやり方するんですね…

### 2/5 — うーん

*2026-06-21*

分離全てをチェックできないのに金は払えねぇよ
しかもヤマハだろ、どうせアップデートもやらずに放置だろうね、制約つけるなら分離を3種類と選べるにしてくれるとかそうすれば自分の使いたいのを選べるってもんだ

### 1/5 — Doesn’t remove tracks

*2026-05-24*

Bs don’t waste your money

### 3/5 — Works fairly well

*2026-05-13*

This seems like a piece of software that should be bought for a one time price instead of a monthly subscription.  It works fairly well with the free option however you’re not able to separate out all tracks with that option and you are limited by the number of tracks that you are able to use.

### 2/5 — サブスク高すぎ

*2026-05-08*

フリー1ヶ月、課金1ヶ月使ってみました。
私には、ピッチ調整が半音単位でしか出来ないのが大きな不満。
440Hzでない音源も多いですから。
フリー版がそこそこ使えたので課金してみたのに、残念ながら大きなメリットはなかったかな。

### 4/5 — キーの表示改善して

*2026-03-09*

めっちゃわかりやすいんですが一つだけ。moisesみたいにキーを変える時+-だけでなくCとかEとか表示してくれるとサイコー！

### 1/5 — Didn’t work at all

*2026-03-03*

I wanted this to work as described. It didn’t work at all. The program crashed every time I hit play. I rebooted and tried. I’m deleting the app.

### 3/5 — Tried it

*2026-02-28*

Didn’t work on iPhone

### 1/5 — Doesn’t work

*2026-02-21*

Imported a song, did the separation, clicked play and it crashes every time
