The Akai EIE Pro MIDI 2964 is an audio interface and MIDI controller produced by Akai Professional. It's part of the EIE Pro series, which is designed for use in digital audio production, offering features like 4x4 audio I/O, MIDI ports, and built-in preamps. The MIDI 2964 part likely refers to the MIDI functionality of the device, which allows for the transmission of MIDI data between your computer and external MIDI devices (such as keyboards, drum machines, and synthesizers).
