phase diagram. The key factors to look at on the scope display are crisp clean lines, round shape, and the tracking percentage in the lower right corner. Start both turntables or CD players. You will see green rings appear in the scope view as shown above. For optimal performance the inner ring should be as close to circular as possible. Use the scope zoom slider (1x to 16x) to zoom in or out as necessary. Use the scope L/R Balance and P/A Balance controls to adjust the shape of the inner ring. The number in the top left corner of the scope view gives the current absolute position within the control record or CD. The number in the top right corner is the current speed in RPM. In the bottom left is the current threshold setting, and the number in the bottom right shows the percentage of readable signal - this number should be close to 85% when your system is calibrated properly. Calibration Troubleshooting After calibration, the number in the upper right corner of the scope view should say 0.0 while the needle is on the record and the turntable is stopped. If that number is fluctuating then manually move the Estimate slider to the right until that number is stable at 0.0. If you've moved the slider all the way to -24 and its still fluctuating then you have a grounding or interference problem somewhere in the chain. If so, the first thing to check is that the grounding wire coming from your turntable is connected to either the SL4's or your mixer's grounding posts. Next, make sure that the SL4 isn't sitting next to a power source such as a power strip or power box and that the RCA cables connected to the SL4 aren't laying across other power conducting cables. If you are still experiencing issues, you might have to adjust the placement of your setup. For example, make sure bass bins aren't directly under the turntables. for more calibration troubleshooting help See "Scope Reading and Fixes" on page 38. Importing and Playing Music Importing Your Music The easiest way to load music into your library is by using the Files button: 1. Click on the Files button to open the files panel. The left side of this window displays various locations on your computer hard drive (and external drives if you have one). Click on these locations to navigate your computer and find your music. By default, your music will usually be found in either "Music" (Mac) or "My Music" (Windows). 2. Once you have located your music, drag the folder or files you want to import onto the purple " All..." icon. This is located to the left of your screen at the top of the crates and playlist window. If you wish to import all of your music, just drag your whole music folder onto this icon. TIP: You can also import by dragging files and folders directly from Windows Explorer (PC version) or Finder (Mac version) into the Scratch Live library. TIP: Adjust the size of the Files window by clicking and dragging near the three dots up or down. The vertical crates window adjusts left and right. Supported File Types Scratch Live supports fixed and variable bit rate .MP3, .MP4, Ogg Vorbis, .AAC, .AIFF, .ALAC, .WAV and Whitelabel (wl. mp3) file types. M3U playlists are also supported.
