Digital Performer 2.1.1 or Later Required
Digital Performer versions 2.1.1 and later are required for use with the 1212 I/O.
Digital Performer versions 2.4 or later are required for support of ADAT timecode.
Configuring Digital Performer
Digital Performer features fully integrated, direct support for the 1212 I/O. If the 1212 I/O is selected as the Sound Manager input and output device, this may cause problems during the initial Digital Performer audio hardware configuration process. Before configuring Digital Performer for use with the 1212 I/O, we recommend temporarily de-selecting the 1212 I/O in the Sound control panel, as described below.
To configure Digital Performer for use with the 1212 I/O:
1. Quit Digital Performer, if it is currently running.
2. Open the Sound control panel.
3. Select "Built-In" for both Input and Output.
4. Open Digital Performer.
5. Make sure that the MOTU Audio System is selected as the Audio System (in the Basics menu).
6. In the Basics menu, select MOTU Audio System options->Configure Hardware Driver.
The Configure Hardware Driver dialog will appear.
7. Select "Korg 1212" from the menu at the top of the dialog.
8. Set the other parameters as desired, and then press OK.
9. Quit Digital Performer.
10. Go back to the Sound control panel, and re-select the 1212 I/O for Input and Output.
Premiere Plug-Ins and Digital Performer
Digital Performer supports Premiere Plug-Ins, as well as Performer's own real-time effects. Premiere Plug-Ins use the Sound Manager for audio output during effects preview. To hear the Premiere effects preview through the 1212 I/O, you will need to set up the Sound Manager to use the 1212 I/O, as described in the 1212 I/O manual.
Digital Performer 2.4 adds some features which make previewing Premiere effects much easier. A few extra steps are necessary with versions 2.3 and earlier.
NOTE: These instructions assume that the 1212 I/O is selected as the Sound Manager input and output device, using the Sound control panel, as described in the 1212 I/O manual.
Setting up the Sound Manager in the 1212 I/O Utility
Before auditioning Premiere Plug-Ins in Digital Performer, you need to make sure that the 1212 I/O Utility is configured properly.
1. In the 1212 I/O Utility, make sure that the sample rate and word clock settings (which are used for the Sound Manager) match those of Digital Performer.
If these settings are different from those in Digital Performer, the preview's pitch may be different than the original audio.
2. Also in the 1212 I/O Utility, select the desired Sound Manager output channels. If you like, these can be set to match the output setting of the audio track in Digital Performer.
Sound Manager audio, including the Premiere Plug-In preview output, is routed to the outputs set in the 1212 I/O Utility. The output settings made in Digital Performer have no effect on the preview output.
Digital Performer 2.4 and later
Digital Performer 2.4 makes it easy to hear Premiere Plug-In previews through the 1212 I/O.
1. Follow the instructions under Setting up the Sound Manager in the 1212 I/O Utility, above.
2. In Digital Performer, go to the Premiere Plug-In Preferences dialog (Audio->Plug-Ins->Plug-In Preferences).
3. Click on the "Release Audio Driver while previewing" box, so that it is blue. Press OK to exit the dialog.
With this option enabled, Digital Performer will automatically release the 1212 I/O for use by Premiere plug-ins.
Digital Performer 2.41 adds a new Preferences option, named "Play in background," which should be disabled when previewing Premiere plug-ins through the 1212 I/O. For more information, see Using Digital Performer 2.41 (or later) with other audio programs.
Digital Performer 2.11 through 2.3
Versions 2.11 through 2.3 of Digital Performer hold on to the 1212 I/O card as long as DP is the active application, which prevents Premiere Plug-Ins from playing through the card via Sound Manager.
You can work around this by temporarily disabling the MOTU Audio System, as described below.
1. Follow the instructions under Setting up the Sound Manager in the 1212 I/O Utility, above.
2. In Digital Performer's Basics menu, select Audio System->MIDI Only.
This temporarily turns off the MOTU Audio System, freeing the 1212 I/O for use with the Sound Manager.
3. In Digital Performer, select the audio to be processed, and select a Premiere Plug-In from the Audio->Plug Ins menu.
4. Set up the Plug-In as desired. The effect preview will be heard through the 1212 I/O.
5. Apply the Plug-In.
The Premiere window will close, returning you to Digital Performer.
6. In the Basics menu, select Audio System->MOTU Audio System.
This will re-enable Digital Performer's MOTU Audio System.
Sample-Accurate Sync (ADAT timecode)
Starting with version 2.4, Digital Performer supports the 1212 I/O's direct ADAT timecode synchronization.
Basic setup instructions
1. In Basic->Receive Sync, under "Type of sync," select "Sample accurate."
2. In Basics->MOTU Audio System Options->Configure Hardware Driver, select the 1212 I/O, and set the Sync Source to "ADAT."
Except when using the original ADAT without a BRC, the Sync Source can also be set to "SPDIF/word clock." Due to hardware restrictions, "Internal" cannot be used when syncing to ADAT timecode.
Remember to set the ADAT's clock source appropriately! See Setting the word clock source on an ADAT system for more details.
For more detailed information on setting up Digital Performer, please consult the Digital Performer 2.4 update documentation.
Use auto-punch
For best results, Korg recommends using Digital Performer's auto punch in/out feature.
Start the ADAT well before the punch-in point
Start the ADAT well before the punch-in point, on the order of 10-15 seconds. Shorter times may work, as long as you always see Digital Performer's counter moving in sync with the tape before the punch-in point arrives.
When using the BRC, turn off Digital Performer's MMC
When using sample-accurate sync in conjunction with an Alesis BRC, Korg recommends that you turn off Digital Performer's MMC (MIDI Machine Control) features.
1. Open Digital Performer's MIDI Machine Control window.
2. Make sure that the MMC Master Button (at the top of the window, between the computer and tape icons) is showing a white arrow; this means that it is deactivated.
3. As an added precaution, set the ADAT/BRC online/offline button to "Offline."
Record Monitoring
Digital Performer's record input monitoring is toggled on and off by the little "headphone" icon at the top of the Audio Monitor window. Make sure that this icon is hilighted.
In DP's current implementation of "direct hardware play-through," each input is hard-wired to the corresponding output - ADAT 1 in always goes to ADAT 1 out, for instance, Analog R goes to Analog R, and so on.
For general information on the 1212 I/O and record monitoring, see Record Monitoring.
Avoiding Feedback
Digital Performer allows you to monitor audio directly through the 1212 I/O (without passing through the MAS effects). This allows zero-latency input monitoring, but -when not properly configured - it also makes it possible to create a feedback loop.
The best solution for feedback is always to figure out what's causing the loop, and then set things up so that a loop is not created. As a shortcut, however, you can either turn off record monitoring altogether (by un-hilighting the headphone icon at the top of Digital Performer's Audio Monitor window), or disable direct monitor routing by doing the following:
1. In the Basics menu, select Audio System Options-> Input Monitoring Mode.
2. In the Input Monitoring Mode dialog box, select "Monitor record-enabled tracks through effects."
Note that, even with this setting, it's still possible to create a feedback loop by routing inputs to outputs in Digital Performer's mixer!
For general information on avoiding feedback, see Avoiding Feedback Loops.
Digital Performer 2.4 features more efficient
MAS
Starting with version 2.4, Digital Performer includes a new, more processor-efficient version of the MOTU Audio System (MAS), which offers greatly improved performance with the 1212 I/O. This means that you can play back more simultaneous tracks, or use more real-time effects.
The improvement comes from a change to MAS, so that it processes only the inputs and outputs actually being used at any given time. (Previous versions always used processing power for all inputs and outputs, whether or not they were being used.) This improvement is particularly noticeable when using audio cards with large numbers of inputs and outputs, such as the 1212 I/O.
For more information, see the MOTU website, at http://www.motu.com/english/software/dp/dp24/mas.html.
For more general information on this subject, see Impact on CPU Processing Power.
Using DP 2.41 (or later) with other audio
programs
Digital Performer 2.41 adds a new option to the File->Preferences dialog box, called "Play in background."
When "Play in background" is enabled, Digital Performer will hold on to the 1212 I/O as long as the program is open. This prevents the 1212 I/O from being used by other audio programs, such as waveform editors. Currently, it also prevents use of the 1212 I/O by Premiere plug-ins - even if the "Release Audio Driver while previewing" is enabled under Audio Preferences.
To allow use of the 1212 I/O by other programs and Premiere plug-ins, disable the "Play in background" option.
