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.

3.3Setting 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.
