"a bit like musical crack" - Synthtopia
TonePad Pro is the easiest and coolest way to make music. Discover the inner musician in you. Create songs by simply touching the screen and seeing notes light up.
The Pro version is all the goodness of TonePad with the added ability to create custom ringtones. Email the ringtone to yourself or a friend. Add the attached ringtone file into your iTunes library on your computer and sync with your iPhone. The ringtone will then be selectable on the iPhone via Settings > Sounds > Ringtone.
If you like Andre Michelle's ToneMatrix or the Tenori-On, then you will absolutely love this app.
TonePad Pro features a clean minimalist user interface with a full 16x16 matrix. The sound quality remains excellent regardless of how many notes are playing at the same time.
You can save an unlimited number of songs. The current song is also saved automatically on exit.
Please use headphones for best sound. Stayed tuned for more customization features to come. If you like the app, remember to share your song codes with the community by writing a review!
