So you want to use your iPad to produce music? You may want to give the RemoFinger a look. It is a handy tool that lets you remotely control any app on your iPad using your foot. This foot controller is compatible with iPhones, Android phones, and any other smart device with a capacitive touchscreen display. Using this tool, you can stop/start recording, change settings, turn the page, and more.
You can control up to 4 channels from the floor. The device has a wireless range of up to 15 meters. The design is lightweight and portable. Yet another interesting Kickstarter project for musicians.
