The Fast Track® Ultra 8 x 8 audio/MIDI interface takes M-Audio’s acclaimed mobile recording line to the next level with high-speed USB 2.0 connectivity, MX Core™ DSP mixer and four preamps with award-winning Octane™ technology. Featuring both analog and digital I/O, it allows recording on all eight channels simultaneously with pristine 24-bit/96kHz fidelity—while M-Audio’s mature low-latency drivers ensure rock-solid stability and performance. The on-board MX Core™ DSP mixer processes eight hardware inputs and eight software returns to the eight hardware outputs, delivering flexible routing and monitoring with delay and reverb. Compatible with most major audio software*, Fast Track Ultra lets you record the way you want—in the studio or on the go.
