The Hotone Ampero Control is an extremely useful controller that allows MIDI signals to be simply and discreetly controlled by foot via the classic 5-pin connector, the integrated USB port or completely wirelessly via Bluetooth . Operating the Ampero Control with its four foot switches always remains straightforward and clear, while providing an enormous variety of different functions. Up to 16 different MIDI messages can be assigned to each individual switch via the easy-to-use mobile app for Android and iOS, while advanced functions such as press/hold commands further expand the range of functions. There are also connections for additional external controllers and expression pedals for real-time control of individual effect parameters on board.
