On Mac
®
systems, Line 6 devices utilize the Mac
®
Core Audio driver system and these audio driver
settings are all handled by the Mac
®
Operating System’s Audio-MIDI Setup dialog. This dialog does
not offer buffer settings for the Core Audio driver. However, some DAW applications do offer their
own audio buffer settings (usually found in the DAW’s Preferences or Audio Setup options).
Audio glitches can be caused by your computer just being too busy processing other tasks from
other software or hardware. When doing anything with POD Farm 2 and/or DAW software on your
Windows
®
or Mac
®
computer, it is always a good idea to shut down all other programs that you do not
need. It is especially important during audio recording on your computer that you are not performing
other tasks on your computer such as copying les, playing your new rst-person-shooter game, or
burning a DVD!
Note that it is specifically recommended that you connect your Line 6 device’s USB directly to a
USB port on your computer, and not into a USB hub. Some USB hubs can cause communication
errors with USB audio devices .
Other computer peripherals can sometimes cause conflicts with your Line 6 hardware, or might be
ghting for use of the same computer resources. You can try disconnecting any USB devices you do not
need while using your Line 6 device if you encounter any such USB device conflicts.
Keep it lean & mean - It is common for pro recording studios to make their computers be dedicated
DAWs (Digital Audio Workstations), meaning they install practically NOTHING other than the
DAW software and plug-ins they use for audio work, as well as limit the installation of peripheral non-
audio hardware as well. Most of us need to use the computer for some other, non-audio tasks, but it’s
good to keep in mind that the more “stuff” you install and run, the greater the chance for software and
hardware conflicts which can diminish the audio performance!
Also note that some USB speakers occasionally create clicks and pops themselves. Listen to your
speakers separate from POD Farm 2 for a while if you suspect this might be the problem.
Hard disk access speed - One common cause of clicks and pops in your recording and playback audio
is caused from your computer not being able to write/read the audio data from your hard disk fast
enough. Most audio recording software will recommend that you use a hard disk that is rated at 7200
RPM disk speed (or faster). It is also not advisable that you use an external hard disk that is connected
via USB 1.0 – instead it should be USB 2.0 or Firewire to ensure fast data transfer for audio work.
On Windows
®
, newer PCs typically utilize the Serial ATA (SATA) interface format for Hard Disks,
which is fast and typically requires no user tweaking. But if your PC utilizes the IDE Hard Disk controller
interface type, check that your internal IDE controller (which controls your hard disk and CD/DVD
drives in your computer) is congured for DMA mode for higher speed operation. To congure your
drives to use DMA mode under Windows:
• Click on the Start button, and select Settings > Control Panel.
• Double-Click the System icon.
• Select the Hardware tab, and press the Device Manager button.
• Select the IDE ATA/ATAPI Controllers tree and open it.
• Check each IDE channel to make sure the Transfer Mode is set to DMA if available.
• You must reboot your machine if you make changes to these settings.
