 PiPedal's user interface has been specifically designed to work well on small form-factor touch devices like phones or tablets. Clip a phone or tablet on your microphone stand on stage, and you're ready to play! Or connect via a desktop browser, for a slightly more luxurious experience. The PiPedal user-interface adapts to the screen size and orientation of your device, providing easy control of your guitar effects across a broad variety devices and screen sizes.
