Tascam US428 USB Digital Audio Workstation Controller (Windows or Macintosh)

Manufacturer's Description for Tascam US428 USB Digital Audio Workstation Controller (Windows or Macintosh)

Tascam and Frontier Design Group have partnered together to create the first major innovation in USB-based audio. Start with a fully 24-bit front end, with 2 XLR inputs, 2 balanced 1/4 in. TRS inputs, 2 unbalanced 1/4 in. inputs (switchable to Hi-Z), and S/PDIF I/O. Four channels of audio in and 2 out simultaneously via USB. No opening your computer, no sound card to install - it's USB, so you can even hot-plug it.

You'll spend a lot less time mousing your mix with the US-428. It's got real tactile controls for the most-used functions in your DAW applications. Transport, mute/solo, and locate keys, unlimited banks of 8 faders, an EQ module that supports control of up to 4 bands of fully parametric EQ, plus 4 aux sends and a panpot. It's even got 32 channels of MIDI I/O. Use one for your keys and modules and the other for MTC to lock your MTC-capable tape tracks to your computer.

The US-428 comes bundled with Steinberg's Cubasis VST audio recording/MIDI sequencing software.
