📝 About this app
Play the ocarina, drums, guitar or even trumpets with this app. They are all integrated!
The sound system of this app allows you to set the pitch of a note on the go (Android 3.0+).
<b>More features:</b>
• You can enable or disable song recognition (so you can play freely).
• In this app, sounds can be held for about 5 seconds and have a soft decay.
• You can change the background of the app anytime (or choose a custom one!)
• You can set the decay level of the sounds.
• You can keep a note pressed and change its pitch on the go as long as the sound lasts.
• Immersive mode (hiding the navigation bar) available for Android 4.4+ users.
<b>Available instruments:</b>
• Ocarina
• Pipes (trumpets)
• Drums
• Guitar
• Harp (BETA, some songs available).
Languages in the app:
• English
• Spanish
• French (Cynthia Soukhavong)
• Italian (Leonardo Zorzi)
• Japanese (Vincent)
Disclaimer:
As stated before, users with an Android version older than 3.0 may not be able to change the pitch (they can't press 2 buttons at the same time since their devices don't support it), but they will be able to play the common notes of an ocarina.
Also, users who have a device with cheap audio hardware may experiment little sound glitches (nothing I can fix), I can only recommend to lower the volume and not to play notes too fast.
