Changes include: • A new and more efficient core synth engine • Rebalanced sounds so each plays at a more even level • The Auto theme now follows your phone's light or dark setting • Improved VoiceOver support • Improved MIDI exports • Fixed an issue where the ARP button did not respond to taps on older versions of iOS • Fixed an issue where the joypad could get stuck when a touch was interrupted • Fixed issues where audio failed to restart after calls or other system interruptions • Many other small fixes

使いやすそう。。

シンプルで使いやすいとは思うがよりコード進行をホールド機能などを追加して把握しやすくしてほしい。また設定画面から操作画面に戻るボタンが無くどう使って良いかわからない。更新に期待

Response from developer

レビューありがとうございます。コードを押し続けなくても鳴らし続けたい場合は、画面上の「CTRL」をタップし、「LOCK CHORD」をオンにしてください。今後のアップデートで、この機能は「HOLD」という名前になり、見つけやすくなります。設定画面からは、画面下のタブバーの左のアイコンで演奏画面に戻れます。また、次の大きなアップデートでは、マイナーなど8種類のスケールと、コード進行がより自然につながるボイスリーディングが加わります。ご意見ありがとうございました。

Nice idea, poor performance

The idea of building an app that makes music and even easy is nice, but to charge for it and have this poor performance shocks me. No loops, no beats provided, just to hammer some notes? Definitely needs a makeover… at this stage of the app I’d very much like to have my money back……

Response from developer

Thank you for taking the time to leave a review. LUMA is still growing, and we're adding new features with every update. There are drum loops included to play along with, but LUMA's main focus is making it quick and enjoyable to create chord progressions on the move. A lot of care has gone into the sound of the synths and effects, and we hope we can change your mind as LUMA continues to grow.

Great synth

Really nice app, looks great and sounds amazing. It was very easy just to get a few chord progressions together and it’s already been updated with new features.

Response from developer

Thank you!

Love it

À Little bit expensive maybe but very interesting to create music.
