Introduction  

 

1.1 Overview 

 

 
The US-224 is a USB controller designed for 
Cubasis and other Digital Audio Workstation 
(DAW) software applications.  Its design 
incorporates a  two-input, two-output 24-bit 
audio interface, a 16-channel MIDI interface, 
and a control surface for your most-used  
mouse functions.   

 

Our goal was to create a device to make  
your DAW software as easy to use as a  
Portastudio. The transport and other 
controls are designed and laid out to look 
and function just like a Portastudio – if 
you’ve ever used a tape recorder, you know 
how to use the US-224.  
 
Because the US-224 is USB based, it’s the 
ideal companion to any desktop- or laptop-
based digital recording setup. And since it’s 
as compact as a laptop, it can be combined 
with one to create a complete portable 
digital audio workstation solution. 
 

 

1.2 Features 

 

 
The input section comprises a 24-bit audio 
interface, capable of streaming two 
simultaneous tracks of audio into your 
computer. Inputs include two balanced XLR 
mic inputs, two 1/4” unbalanced line inputs 
(switchable to high-impedance, for direct 
input of a guitar, bass or other hi-Z source), 
and an S/PDIF digital input.  Outputs include 
a pair of unbalanced line outputs on RCA 
connectors, S/PDIF output, and separate 
headphone output. 
 
The US-224 also features MIDI Input and 
Output ports, allowing you to send and 
receive data and MIDI Time Code (MTC) 
from your MIDI-based keyboards and other 
devices.   

 

 
 

 

 

 
 

 

The US-224’s control surface includes a 
variety of controls which make working with 
audio software faster and easier. The 
channel section of the control surface 
consists of four channel faders (plus one 
master fader), four MUTE/SOLO buttons, a 
switch to toggle Solo and Mute functions, 
and individual record-ready and select 
switches. The master section features a 
DATA wheel, PAN control (assigned by 
pressing the channel SELect key) and 
dedicated transport and locate controls, 
offering one-button access to these often-
used functions.
