8. Other Applications and 
US-428 Emulation Mode 
 
As we’ve mentioned throughout this manual, 
the US-224 is an extremely versatile device.  
Its capabilities as a controller go well beyond 
those we’ve described thus far with the 
bundled Cubasis program.   
 
Since the US-224 is based on TASCAM’s 
very popular US-428, it is capable of 
providing basic functionality in most of the 
applications supported by the US-428 
(subject to its hardware limitations). 
 
Clearly it would be impossible to...

Manager Support 
(for use with 
ProTools Free and Other MacOS 
Applications)  
 
The Macintosh Sound Manager is a 
standard 2-channel software interface for 
playing and recording sound on a Mac. The 
audio inputs and outputs (speakers) that are 
built into any Macintosh use the Sound 
Manager interface, and essentially every 
Mac application that uses sound supports it. 
This includes not only audio recording and 
editing programs, but also games, video 
editors, web...

used to enable or mute the US-224 output. 
 
Under “Sound In” you can select the “US-
224” instead of the Mac’s Built-in sources.  
You can also do this under the “US-224” 
control panel’s “System” tab. There you will 
find a field labeled “Sound Manager Input”. 
You can change this setting at any time, 
even while a program is using the Sound 
Manager I/O....

likely to encounter will be related to the 
software you’re using, it’s a good idea to 
check not only our website, but the websites 
and resources of the software program’s 
manufacturer as well.

Provide simple, effective integration between the US-224 and host software applications. 
 
 
Introduction 
 
The US-224 provides digital audio I/O, MIDI, and control surface functions in a single affordable 
USB-based product. W hile the audio and MIDI I/O follow established which are easily interfaced 
with host applications, full integration of the control surface aspects of the US-224 requires a set 
of messages to be defined which permits...

 
38 Transport/Locate command set 
 
The US-224 contains a set of standard transport switches: REW , FFW D, STOP, PLAY, and REC. 
In addition, dedicated status LEDs are used to communicate the current transport state to the 
user. The LEDs indicate REW , FFW D, PLAY, and REC. (Note that there is no LED to indicate 
STOP.) Additionally, there are three locate switches, which can be used to set and locate to 
markers established on the host applications timeline. SET is intended to be used as a SHIFT 
key,...
