ASIO drivers (MacOS)
Logic Audio 3.6 (MacOS) adds support for ASIO hardware. This means that you can now use Logic Audio and the 1212 I/O in two ways: via Logic's direct 1212 I/O support, or via the 1212 I/O's ASIO driver.
To use the 1212 I/O with ASIO, you'll need to place the 1212 I/O ASIO driver in a folder named "ASIO Drivers" (without the quotes), in the same folder as the Logic Audio folder application. Logic Audio 3.6 does not automatically create this folder; if necessary, create the folder yourself.
For more information on working with ASIO audio hardware, please see the Logic Audio documentation.
You can download the current version of the MacOS 1212 I/O ASIO driver from the Steinberg website, as described under Downloading ASIO Drivers.
ASIO drivers (Windows)
Logic Audio for Windows 4.02 (or later) is required for use with the 1212 I/O ASIO driver. Earlier versions are susceptible to a communication problem during the initialization of the driver.
ADAT Timecode Sync
Logic Audio does not currently support the 1212 I/O's ADAT timecode functionality.
For timecode synchronization, you will need an ADAT-to-MTC converter, such as the JL Cooper DataSync or DataMaster, MOTU MTP-AV, Opcode Studio 64X, Steinberg ACI, Alesis BRC or AI-2, etc.
Prices for these vary from around a couple of hundred US dollars for the DataSync and ACI to about US$1500 for the BRC.
You could also stripe the ADAT tape with SMPTE, and then use a SMPTE-to-MTC converter, but it is probably best to use one of the above ADAT-to-MTC products instead; they offer a more direct approach, and also do not require sacrificing an audio track to SMPTE.
Hopefully, a future version of Logic Audio may eventually support the 1212 I/O's ADAT timecode functionality.
"1212 I/O: Error 2 Failed to initialize device"
(MacOS)
Logic Audio has the ability to use multiple audio devices simultaneously - such as Mac AV (Sound Manager) and the 1212 I/O. This is generally a very cool thing. However, if the 1212 I/O is selected in the Sound control panel for Sound Manager input and output, this can cause Logic to try to use the 1212 I/O twice: once via Sound Manager, and then via the direct 1212 I/O driver.
Here's what can happen:
If the 1212 I/O is selected for Sound Manager input and output (in the Sound control panel), AND Mac AV sound I/O is enabled in Logic Audio (in addition to the 1212 I/O), then...
Upon bootup, Logic Audio will sign onto Sound Manager, which will in turn take control of the 1212 I/O, and then...
LAM will next try to sign onto the 1212 I/O. The 1212 I/O is already occupied by the Sound Manager, so LAM will not be able to take control of the hardware.
LAM will then display the error message, "1212 I/O: Error 2 Failed to initialize device."
Fortunately, there are two ways to solve this.
either:
A. Disable Mac AV in Logic Audio. To do this, go to Options->Audio Setup->Audio Extensions, and make sure that the box next to Mac AV is not checked.
Or:
B. Leave Mac AV enabled in Logic Audio, but select Built-In as the input and output hardware in the Sound control panel.
Premiere Plug-Ins (MacOS)
Premiere Plug-Ins use the Sound Manager for audio output during effects preview. As of this writing, the current version of Logic Audio (3.5) holds onto the 1212 I/O card as long as it is the active application. This makes the card unavailable to the Sound Manager, and thus prevents Premiere Plug-Ins from playing through the 1212 I/O.
You can still hear Premiere Plug-In previews in Logic Audio, through the Mac's built-in audio outputs. To do this:
1. Go to the Sound control panel.
This control panel selects the hardware used for Sound Manager input and output.
2. Under both input and output, select "Built-In," instead of the 1212 I/O.
Record Monitoring & Avoiding Feedback
(MacOS)
For proper record monitoring behavior with Logic Audio for MacOS, make sure that the faders are set to "0" for the 12 input objects. When tracks are record-enabled, LAM automatically opens the appropriate input faders, even though they still show a value of "0."
If the faders are manually set to a non-zero value, the inputs will be permanently open, and Logic will not automatically switch them on and off.
For general information on the 1212 I/O and record monitoring, see Record Monitoring.
Setting the input object faders to "0" will also prevent feedback. For more information on this topic, see Avoiding Feedback Loops.
Using All 12 Inputs and Outputs (Windows)
Logic Audio for Windows uses the standard Windows multimedia (MME) drivers when working with the 1212 I/O. Logic Audio 3.5 (or later) adds support for multiple soundcards, which is necessary for full 12-in, 12-out functionality; previous versions were limited to stereo I/O only.
To use the 1212 I/O with Logic Audio, go to Logic's Audio Extensions preferences, enable Logic's PC AV audio extension, select the 1212 I/O, and enable multichannel operation. Additionally, Logic Audio requires that you to set up various parameters when using MME devices, using the MMSetup utility, included with Logic Audio. Briefly:
1. Open Emagic's MMSetup utility (in the Logic Audio directory).
The MMSetup window allows you to select the audio hardware used for recording and playback via the PC AV audio extension.
2. In the "Recording" list, select the first 1212 I/O device (1212 I/O ADAT 1-2).
3. Under "Recording," enter "6" into the Number of Drivers parameter (one for each stereo pair).
4. Also under "Recording," enter "2" info the Number of Outputs per Driver parameter (since each output is stereo).
5. Set the parameters under "Playback" to match those for "Recording."
Logic Audio will now have access to all of the 1212 I/O's inputs and outputs.
MouseWare Trackball and Logic USB Dongle
(MacOS)
We have had a ser report a problem with a PowerMacintosh G4, in which Logic showed the error "Korg 1212 caused an unexpected error" on startup, and then when Logic quit, the MacOS showed another error related to "Control Bar."
In this case, the user discovered that the problem seemed to be due to a conflict between the Logic USB dongle and the MouseWare System Extension for his USB trackball. As soon as the user disabled the extension and switched from the trackball to a USB mouse, the problem was solved.
At this time, we do not know why Logic reports this as a 1212 I/O problem, but it seems to be related solely to the USB conflict described above.
