If you’re looking for a way to control your external AU/VST plug-ins, you can now use the iPhone front-facing camera as an "expression pedal" with facial expressions!
Control your MIDI devices using your lips. Just say "wah wah" and send corresponding MIDI events wirelessly. Using your camera instead of an expression pedal or MIDI controller knob provides the ability to use any external AudioUnit/VST effects in a whole new way. Now you can control the VST plug-in settings in real-time without using your hands.
It is a fascinating step into exploring accessibility in music-making. You will discover that our face controller may be more intuitive and easier to learn than a foot pedal.
Why not to change the plug-in parameters in the Amp Simulator while playing using your lips? Now the wah-wah pedal or any other effect will be within reach of your iPhone.
You don’t have an expression pedal slot on your keyboard? Now you can use the Wah-Wah app to control volume, modulation, pitch or any other parameter hands-free. You get one more place to work with effects!
