The Lexicon I-ONIX U22 MIDI is an audio interface that combines an audio input/output device with a MIDI interface. The MIDI functionality allows the device to connect to MIDI-compatible equipment, such as keyboards, synthesizers, and drum machines, and transfer MIDI data to and from your computer. The I-ONIX U22 is typically used in music production, digital audio workstations (DAWs), and other multimedia applications.
The Windows driver for the Lexicon I-ONIX U22 MIDI ensures that your computer can correctly recognize and use the interface's features (including both audio and MIDI functionality). Without the driver, your Windows operating system may not be able to properly interact with the device, meaning you won't be able to use it in your DAW or other audio software.
