Tapper is basically a drum pad, but one that allows you to use your own sounds!
With Tapper you can choose your sounds to associate with up to 20 drum pads. Upload your sound files using your PC's web browser and WiFi. You can categorize the sounds with the use of folders.
The pads can be moved around and saved to profiles. Profiles also save the pad to sound file associations. Save as many profiles as you like.
If you like you can set background music to play along with. Its volume can be adjusted.
You can record your compositions using the built in mic. Press the Record button and give it a name, it will be saved in the Recordings folder ready for WiFi download to your PC, pad association or background music.
New! Now allows Sticky Pads, where the sound is looped until the pad is depressed. Configure which pads are sticky using Settings/Sticky Pads. Profiles will save these settings.
Important: To activate the top menu use a three finger swipe down.
