The M-Audio ProKeys Sono 88 is a semi-weighted, velocity-sensitive 88-key digital piano that also functions as a USB-compatible MIDI controller and a built-in audio interface. It allows users to play on-board premium keyboard sounds as a standalone instrument or connect microphones and instruments to record and produce music via a computer using the included software.
The device supports both class-compliant operation without drivers and enhanced functionality with installed M-Audio drivers, which reduce latency and enable multi-client usage in Windows. The guide details hardware connections, including XLR microphone inputs, instrument inputs, and various audio outputs, as well as instructions for configuring the keyboard's voice selection, layer mode, and MIDI routing.
