The application MIDI Expression Pedal converts your foot’s movement into a stream of MIDI messages, which makes it a practical tool for controlling thousands of VST plug-ins.
In order for the application to become a full-fledged, physical device, you just have to add an original, wireless cardboard expression pedal.

The Expression Pedal Kit is a completely new approach to working with MIDI.
Flexible, comfortable and surprisingly intuitive when used with your DAW.

And this Expression Pedal is really special

MIDI control using your foot is incredibly comfortable, frees your hands so you can play, and now it is possible without complications or unnecessary expenses – you just need your iPhone.
The free iOS app gives you the ability to transfer MIDI events to your DAW, and this pedal was designed specially for the iPhone.
This is the first and only pedal built 100% from renewable resources.
It is made with great care and attention to detail, thanks to which it is extremely strong and durable after folding.

The Cardboard Expression Pedal is iPhone compatible and can be a great way to revive your older model.
The app is supported by all phones from the first generation SE model, and the pedal has a specially adapted tray for this and all subsequent iPhone models.

DIY Template

You can also download the design files below for free and follow the instructions to make the pedal yourself.
You will need a cardboard box, knife or scissors, and about 15 minutes.

You can always paint it if the current color does not appeal to you. The best option is to use acrylic based spray paint. Make sure to test the paint on a different piece of cardboard before painting the pedal, and do it outside to avoid unnecessary cleaning!
