21.1. USB PORTS.
The Seven includes a Type-A “host” USB 2.0 port. This is mainly used for updating the software in case a
new release is available.
Another interesting use for this port is the possibility to connect a “Class-compliant USB-MIDI device”, i.e.
one of the many MIDI devices that don't need special drivers when they are connected to a computer. The
Seven will automatically recognize USB-MIDI devices and will use them to control parameters or play
notes. Any MIDI unit can be connected, for example a keyboard, a pedalboard or a control surface. Please avoid connecting
unsupported devices to this port. Please note that this port can supply a max of 250 mA of current. Do not use this port to charge
mobile devices.
An additional Type-B USB 2.0 port is present at the back side of the Seven that provides Class-compliant USB-MIDI
IN/OUT connection to your computer. Use this port to connect the Seven to your computer software. No drivers are
needed for Windows, OS X and Linux.
