Touchscreen technology offers interesting possibilities for musicians. With Singing Fingers you can make interesting sounds on the iPad or iPhone while drawing on the screen. You can make sounds by singing or playing an instrument while drawing with your finger on the touchscreen. Watch this video for a demonstration of Singing Fingers:
The sounds recorded are quite distorted during play back, so that’s not the fault of the microphone on your device. The beta version is available now for iPhone, but it also works on the iPad. The special iPad version will be released later.
