2. Once you ve enabled your tracks you ll want to monitor audio through them to set your levels Open Cubasis Monitor Mixer Audio Monitor menu and make certain you ve assigned your channel inputs and enabled them You should see audio signal on those channels meters assuming you re sending signal from your source If your input signal is too high the OL LED will glow steadily red If the signal level is too low you might only see a flicker or nothing at all on the SIGNAL LED You can regulate the input level of the input source in several ways First make sure that the signal you re sending to the US 224 is within a reasonable range it should illuminate the green SIGNAL LED but the red OL LED should only flicker occasionally You can then fine adjust the level with the TRIM knobs for the selected channel s NOTE The SIGNAL and OL LED s do not function with digital input In the case of digital input input level is regulated by the output level of the source and passed directly to the software application without modification On Cubasis Transport Bar you can enable the recording to drop in or out of Record based on the locate points you ve set If you do not wish to enable this function make certain the buttons for drop in and drop out are not enabled Press the RECORD button on the US 224 If you ve got the metronome s Count off function enabled you ll hear a one or two bar countoff and then the pr
3. NOTE The drivers of many other USB devices especially CD burners scanners printers and cameras are written to poll the USB buss on a regular basis usually once every millisecond This can lead to dropouts clicks pops and other artifacts in your audio We strongly suggest unplugging any non essential USB devices while recording with the US 224 USB keyboards and mice are the notable exceptions in most cases they are passive devices with very minor bandwidth requirements Another well documented advantage of USB is the ability to hot plug devices that is plug them in and out without powering the computer down While this applies to the US 224 as well we recommend against plugging or unplugging or powering the unit on or off while running your audio application Doing so can result in audible pops or even hanging or crashing the program You ll find a listing of web links and resources on hard disk recording on our website at www tascam com 4 Hooking up Audio and MIDI to the US 224 4 1 Hooking up audio To monitor output from your computer connect the analog outputs of the US 224 to your mixer amplifier or powered monitors Output volume is controlled by the LINE OUT level pot If you ve got a digital mixer external D A converter or other device with S PDIF input you may prefer to monitor via the US 224 s S PDIF output a Y Illustration 4 01 Connecting audio to the US 224 To
4. MTC MIDI Time Code This allows you to sync tracks from your MTC capable Portastudio DTRS multitrack or any other machine that accepts time code with your digital audio software for transferring tracks back and forth for editing and processing 4 3 Using the Input Monitoring In digital 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 The INPUT MONITOR mixer built into the US 224 eliminates this problem by providing a way to listen to the signals you re recording directly without any computer processing delay When the INPUT MONITOR button is depressed the first two channel faders control the input levels of inputs A and B to the US 224 s internal mixer Changes in these levels affect the monitor and headphones outputs but have no effect on the audio levels seen by the audio software application The first two MUTE buttons also affect the inputs and PAN is also available in this mode the inputs come up panned to center but can be SELected and PANned anywhere within the stereo field OTE n INPUT MONITOR mode faders 3 4 are inactive NOTE All the controls mentioned here are also accessible via the ASIO control
5. 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 Con
