Setting up and Using the US-428 with Pro Tools
®
The US-428 can control Digidesign's Pro Tools software application on both the MacOS and the PC.
Digidesign offers a free version, ProTools Free, that is an attractive application for use with the US-428.
On the Macintosh it uses SoundManager for audio, and Windows Multimedia (MME) on the PC. You can
see compatibility details and can order a free CD-ROM of Pro Tools Free at www.digidesign.com.
Note: At the time of this writing, the downloadable MacOS version (5.0.1) supports the use of remote
control hardware, but the Windows version does not. The CD-ROM version of ProTools Free, however,
contains control hardware support in both MacOS and Windows versions, and thus should be quite
compatible with the US-428. If you have the downloaded Windows version, you can download the
additional files necessary for control hardware support. As of this writing, this file is located at:

Pro Tools Free: This free software application offers eight tracks of digital audio and 48 tracks of MIDI.
You can record up to two inputs simultaneously, and use the US-428 control surface to control mixing,
plug-ins, automation, and more.
Before using the set-up information provided in this document, first install Pro Tools Free (and OMS if
you’re on a Mac) as described in the ProTools document "PT FREE Quick Start Guide.pdf" that comes
with the Pro Tools Free download. Make sure that Pro Tools Free is working using your computer's built-
in speaker before proceeding further. You can use the sample project provided with Pro Tools Free to test
it.
To use the US-428 in this set-up, you must have version 2.00 or later of the US-428 driver installed on
your system. Before using this set-up document, first read the documentation on installing the US-428
drivers.
Setting Up the US-428
Pro Tools Free can only use Sound Manager input and output on the Mac or Windows MME input and
output on the PC. Note that this is not required though. For example, you can use the US-428 to control
Pro Tools while sending Pro Tools’ audio I/O through a different device, even the Mac’s built-in sound
system.
Version 2.00 and later of the US-428 driver includes special emulation software to let the US-428 act like
a JL Cooper CS-10™ attached to Pro Tools. This is different than the normal CS-10 emulation mode
since Pro Tools uses it in some special ways. In the US-428 control panel, select “Pro Tools® CS-10” for
the control protocol.
You might need to adjust the audio latency for your system. Do this in the System tab of the US-428
control panel. Using a smaller setting will reduce the audio input to output latency through Pro Tools Free,
but also increases the chance of audio drop outs. A setting of 1024 works well on many computers. If you
get an error message when playing that says “You’re running out of CPU power. Take out some plug-ins
