The Soundcraft multichannel USB audio driver v3.20 is a low-latency, ASIO-compliant (Audio Stream Input/Output) driver designed to enable high-channel-count digital audio transfer between Soundcraft mixing consoles and Windows-based digital audio workstations (DAWs).
Unlike standard USB audio drivers that support only stereo input/output, the "multichannel" designation is key. This driver allows consoles to appear as a multi-input/multi-output audio interface to software like Ableton Live, Cubase, Logic Pro (via Windows), FL Studio, Reaper, and Pro Tools.

After installation, your Windows PC will recognize the Soundcraft unit as an audio interface. For specific mixers like the Ui24R, standard computer audio is typically routed to the last two channels (e.g., USB channels 31 and 32), while physical inputs (1-24) are mapped to DAW inputs starting from channel 11.
