11. USB Host jack
USB MIDI hosting jack accepts
Class-Compliant USB MIDI devices
only. In general, USB MIDI devices
that require a software driver to
operate are not Class-Compliant.
Accepts a powered USB 2.0 or 3.0
hub to access up to eight Class-
Compliant MIDI devices.
Note: Some USB MIDI devices may
require more power than can be
supported directly by the mio4 in
bus-powered mode. The available
power can be increased by using
the optional power adaptor or
connecting a powered USB hub. We
recommend looking for the "USB
Certified" sticker to ensure your
hub meets USB power standards.

Supports up to four Network MIDI
sessions, each with a single bank of
16 MIDI channels.

router for wireless MIDI.

13. Power supply jack
mio4 may also be powered by the
optional iConnectivity power
adapter (9V @2A 18W, 2mm). This
allows operation without a
computer, and provides increased
power for devices connected to the
USB Host jack.
