3 – Installation System Requirements PC (Windows) Minimum requirements: Pentium II - 266 MHz (or equivalent) processor running Windows 98 (Second Edition) or Windows Me (Millennium Edition), Windows 2000 or Windows XP, 96MB RAM. Recommended: Pentium II 300MHz processor with 128MB RAM or better (these requirements are for use with Cubasis VST. Other applications will have different requirements. Consult your application’s manufacturer for further information). which utilize Intel-based chipsets.
3 – Installation sional incompatibilities. While most OHCI systems have no problems with the US-122, occasionally some older OHCI systems will exhibit problems. We have found that, in the majority of these rare cases, a PCI-based USB card utiliz- ing an Opti-chip controller will work dependably. These cards (also available in PCMCIA format for laptops) are available through a number of manufacturers. Mac OS PowerPC running Mac OS 8.6 or better, and a USB port.
3 – Installation Installation under Windows The US-122 drivers are available on the CD as executable installers. You’ll find two executable installer files in the Driver folder on the disc, labeled as: US122_Win9x_x_yy.exe (for Windows 98 Second Edition and Me (Millennium Edition)) and as US122_Win2k_x_yy.exe (for Windows 2000 and Windows XP) where x and yy represent the version numbers. Note that we have also included the individual driver files, available from the root level of the CD.
3 – Installation To install under Windows 2000 or Windows XP: NOTE Run the Installer with the US-122 NOT connected to the computer. 1 Double click on the executable file US122_Win2k_x_yy.exe (the US-122 setup icon). The installer will run. 2 Click the Next button. The Welcome dialog box will appear. 3 Click the Next button. The driver files will be installed to your hard drive.
3 – Installation Macintosh NOTE 2 Double-click on the appropriate US-122 installer package to expand it. Run the Installer with the US-122 NOT connected to the computer. There are two files for the Macintosh: 3 Double-click the resulting installer file, and follow its instructions. • US-122_OS_9_x_yy.hqx for pre- OS X systems (OS 8.8 and above) • US-122_OS_X_x_yy.sit for OS X systems (OS X 10.2.3 and above) Where x and yy refer to the version numbers of the software.
3 – Installation nected MIDI ports. At the least you should see two icons pertaining to the US-122 specifically: the US-122 icon, and the US-122 MIDI port. Once OMS setup is successfully completed, you can proceed with setting up the US-122 with your chosen application. Please refer to the specific documentation for your application for more details. Tuning Your PC A few words about computers and audio.
3 – Installation minimum system requirements, increasing your computer's RAM as much as possible will markedly improve performance. Consider the addition of a dedicated hard disk for audio; preferably one with a high spindle rate (over 7200 rpm and a seek time of 8.5ms or less is recommended for most audio applications). Using different drives for program and audio data speeds up the seek time for the audio track data.
4 – Hooking up Audio and MIDI to the US-122 Hooking up audio To monitor output from your computer, connect the analog outputs of the US122 to your mixer, amplifier or powered monitors. Output volume is controlled by the LINE OUT level control. To record audio from the US-122 into your computer, simply connect a device to the appropriate input. Microphones should be plugged into the L and R MIC IN XLR inputs.
4 – Hooking up Audio and MIDI to the US-122 Using Direct Monitoring In digital and computer audio, the amount of time it takes for the input signal to pass through the circuitry of the unit and the software processing and arrive at the outputs will sometimes result in an audible delay (this is commonly referred to as “audio latency”). This added delay can be confusing when, for example, you’re trying to overdub to previously recorded tracks.
5 – The US-122 Control Panel Main Page The following description applies to both the Windows and Mac OS versions of the US-122 Control Panel program. You access the Control Panel at the following locations: • Mac OS (pre-X): Control Panel • Mac OS X: /Applications/ In the Control Panel’s main page, you can specify a number of the US-122 options. • Windows: Control Panel Buffer Size Adjustment The US-122 driver temporarily stores input and output audio samples in buffers.
5 – The US-122 Control Panel Optimizing the USB There is another option available which allows you to disable the audio, and only use the MIDI facilities of the US-122. This is useful if you have a high volume of MIDI data to be transmitted through the interface and the timing is critical. The Chromatic Tuner Open the US-122’s control panel and select the Tuner tab. 440 Hz for a middle “A” note, but you can use the up/down arrows to change it to a number between 430 and 450 Hz.
6 – Interfacing with your Audio Software This section is intended to present the basic concepts needed to interface the US-122 with the bundled Cubasis VST application. This discussion, however, is not intended to replace your software’s user’s manual. If you’ve got questions specific to Cubasis, please refer to the Cubasis User Manual for further detail. Selecting the US-122 as your Audio Device Audio Control Panel In Cubasis, open the Audio Control Panel.
6 – Interfacing with your Audio Software Setting the Sample Rate and Bit Depth The US-122 supports sample rates of 44.1kHz and 48kHz. In the Audio Control Panel, select the pull-down menu for Sample Rate and select either 44.1 kHz or 48 kHz. The US-122 control protocol includes two separate drivers for 16-bit or 24-bit operation. This selection is made in the Audio Control Panel (see the illustration). NOTE The bundled Cubasis VST supports only 16bit audio.
6 – Interfacing with your Audio Software Highlight a track in the arrange window, and that track will automatically be record enabled. Verify that the drop-in and drop-out features in Cubasis (on the transport bar) are not enabled (or if so, that they are enabled at the desired locate points). Press the RECORD button on the screen. Cubasis will issue a one or two bar count-in (depending on what’s set in Cubasis’ Metronome preferences menu), then commence recording.
7 – A Sample Recording Session in Cubasis Okay. You’ve got your US-122 connected to your computer, and you’ve loaded the drivers. Your audio software is loaded, and you’re ready to cut some tracks. Let’s walk through a typical recording session with the US-122 and Cubasis. NOTE This chapter is intended as a quick start guide toward recording and mixing with Steinberg Cubasis and the US-122. It is in no way meant to be a comprehensive guide to Cubasis.
7 – A Sample Recording Session in Cubasis in the Options/MIDI Setup menu. For more information on setting up VST’s very sophisticated MIDI functions, please refer to the VST manual. Connect your audio sources to the US122. Connect an analog source via the XLR or 1/4” inputs. Recording Your Tracks In Cubasis, choose the input(s) you wish to enable on the US-122. In the Audio menu, select Input, and click on the input pair on the US-122.
7 – A Sample Recording Session in Cubasis Overdubbing To overdub more tracks, simply select and enable additional tracks as you did the previous ones, and repeat the procedure. You can monitor the tracks you’ve already recorded via the US-122’s outputs, while recording additional tracks into Cubasis via the US-122’s inputs. Be sure to assign each track to its own channel in the program’s internal mixer.
8 – Other Applications It’s important to note that the US-122 is fully functional as a 16- and 24-bit audio interface and 16 channel MIDI interface with virtually all Windows and MacOS compatible applications. Since the US428’s release, TASCAM has been working together with developers throughout the professional audio industry and beyond to create support for new applications; much of this research will also benefit users of the US-122.
8 – Other Applications When an application is using the Sound Manager inputs, this Input Source field is grayed out, displaying the current inputs but preventing you from changing them here. You can still change the input pair without quitting your program, however. To do this, bring up the US-122 control panel and go to the System tab. You will find a selection there labeled Sound Manager Input. Here you can change the input pair at any time, even when an audio program is active.
8 – Other Applications Setting audio I/O options under OS X (10.2.3 and above) In Mac OS X, you can set the preferred audio input and output device using the Sound Preference Pane, or very often you can select the audio input and output devices from the applications themselves. To use the System Preferences: From the Apple menu, select System Preferences and click the Sound icon. Click the Input tab and choose the TASCAM US-122 as the input device.
9 – Technical Support Troubleshooting (Windows) When installing the US-122 for the first time, if you experience any unusual behavior, here are some things to check: Audio Drivers In Control Panel / System / Device Manager (Win98SE/ ME) or Control Panel / System / Hardware / Device Manager (Win2000/ XP), find the Audio control panel.
