3.2.2 Macintosh
Insert the CD-ROM into the computer,
double-click on the US-224 installer, and
follow its instructions.
Connect the US-224 to the computer, and
connect power to the unit. When the US-224
is connected and powered up, the Mac will
find the drivers itself.
3.3 Setting Up OMS (MacOS
Only)
Cubasis, ProTools and several other
applications rely on OMS for MIDI
implementation. OMS (Open Music System)
is a standard for MIDI management on the
Macintosh. Since the US-224 relies on MIDI
controller commands for its communication
with the host computer, you will need to
install OMS. (The exception is Digital
Performer, which utilizes FreeMIDI. The v3
drivers support OMS and FreeMIDI
independently.)
To set up OMS to work with the US-224:
First, run the OMS installer. If you do
not have the current version of OMS, it
may be freely downloaded at
www.opcode.com.
Locate the “US-224 Drivers” folder,
which was placed on your desktop when
you ran the US-224 installer. In this
folder, locate the US-224 OMS driver.
Drag the US-224 OMS driver into the
OMS folder inside your System folder.
Do not drag this file into the Opcode
folder on your hard drive – it will not
work correctly.
Restart your computer. Then turn on
the US-224 and start the OMS Setup
application (located in the Opcode folder
on your hard drive).
Select “New Studio Setup” from the File
menu. When prompted to select a serial
(modem or printer) port, leave both
selections unchecked. Click yes and
continue. OMS will assess all the MIDI
ports attached to your computer and
build OMS instruments for the ones it
recognizes.
When the setup is complete you should
see a list of all your connected MIDI
ports. At the least you should see three
icons pertaining to the US-224
specifically: the US-224 icon, US-224
MIDI port and US-224 Control port.
(US-224 Control is the “virtual” MIDI port
with which the US-224 and its control
surface communicate with your host
application.)
Once OMS setup is successfully completed,
you can proceed with setting up the US-224
with your chosen application. Please refer
to the specific documentation for your
application for more details.
3.4 Tuning Your PC
A few words about computers and audio.
Much has been written about the best ways
to optimize your PC for handling audio
applications, and generally speaking, it’s a
much deeper topic than we’ve got space for
in this manual. But here are a few basic
points to help you get the best out of your
audio programs:
Don’t run extraneous applications. While
it’s likely you’ll sometimes use your
computer for applications other than
audio, it’s strongly recommended that
you avoid running other applications at
the same time you’re running audio
programs. Processing digital audio
requires considerable overhead from
your computer, so don’t overtax the
system by running other applications
(especially graphics or internet tools)
that can steal those resources.
