### 5/5 — よくできてる

*2025-10-17*

元々kaiser toneを愛用している者です。
プラクトンはボーカルと楽器を分離するのにいいアプリです。
アップサンプリング機能があるのでDACを繋げば分離した音を768khzで聞けるのでとってもいいです。
曲によっては練習にとっても使えるので個人的には満足しています。

### 1/5 — 機能していない

*2025-09-03*

曲が途中で終わってしまう。説明も無いのでどうすればいいか分かりません

**Developer response:** ご利用いただき、ありがとうございます。
ご指摘の「曲が途中で終わってしまう」件についてですが、以下の2つのケースが考えられます。

（1）ユーザー設定でアプリの「音楽再生モード」を「メドレー」に設定されている場合、それぞれの楽曲の再生時間が最大2分以内の任意時間で連続再生されます。

（2）アプリを「無料版」でご利用いただいている場合、楽曲の再生時間が最大2分に制限されております。

これらの点については、App Storeのアプリ説明文、およびアプリ内のヘルプページにも記載しておりますので、ご確認いただけますと幸いです。

なお、プレミアムモードを一定期間無料でご体験いただける方法もご用意しておりますので、よろしければぜひお試しください。
