What’s New

Version 5.0.0

The playlist specifications have been greatly updated.

* Song registration policy
The link of the song selected from 'Music Library' is kept in the app, and the link of the song is created as the playlist.
(For songs registered before Ver.4, the playlist converted into song links will be generated.)

Similar changes have been made to files read from outside (such as 'Voice Memos').

* Policy for retaining effect settings
Changed to keep the setting value of the effect (pitch / EQ value, AUv3 selection state) for each song.

* Export
You can export by tapping the mark at the right end of each song on the playlist screen.
You can reflect each value of the effect (pitch / EQ) set for each song.

One HUGE issue

It was working great until recently. Now I’m having an error where I can’t add any new songs. I hope this gets fixed

As a non-professional avid transponser, I have bought so many songs on Apple Music for this app. I absolutely LOVE how easy it is to navigate, how transposing works, how simple adding songs into the queue is, etc. Only issue is not being able to pause from outside of the app, but that isn’t a huge deal! I love being able to show my friends the power of transposing music ❤️

Perfect for songwriters on the go

I downloaded this app specifically to experiment with keys of new song ideas in the car. It’s been exactly what I was looking for. Throw down a piano part and you can figure out where you want your vocal melodies to sit during your car ride instead of having to be at your workstation. Super helpful. 👍🏻
