PokéBan is an app that lets you play professional accompaniments anytime, anywhere.
Not only can you play back, but you can also adjust the tempo, key, and repeat playback to customize the accompaniment to your liking, allowing you to practice to your heart's content.
It also has a recording function, so you can immediately see the results of your practice.
You can apply effects to the recorded audio, adjust the balance with the accompaniment, and export it to a file format playable on music players, etc., for emailing or uploading to a server.

This app includes accompaniments based on the scores of Zen-On Music Publishers' "Italian Songs 1 (38 songs)," "Bellini Songs (15 songs)," and "Tosti Songs 1 (40 songs)." (Piano accompaniment: Sayaka Teramoto)
Songs can be accessed through in-app purchases. You can purchase individual songs or the entire collection.
Five sample songs are pre-installed: "Le violette," "Tu lo sai," "La Farfalletta," "Malia," and "Segreto."

Songs will be updated in the future.
