Access the ScrewLab Download page. (See Resources for download page link.)
Read the specifications below the download link to select the one you desire. Click the download link for the version you desire. (Two versions will be available for downloading: ScrewLab Platinum and the ScrewLab basic version.)
Click the "Save" action when the file download window appears. Click "Next" on each of the InstallShield download screens to select all of the ScrewLab recommended settings and installation preferences.
Select "Done" when ScrewLab initial screen opens with the speaker options. Do not change any of the speaker settings because they determine the balance of the chopping effects for the song. (ScrewLab will open with two split players: one on the left and another on the right side.)
Click the "Add Both" button below the left player. Locate the song from your hard drive files, highlight the file and click "Open." (The song will play automatically, in both players.)
Click the "StopBoth" button in the middle of the application screen to stop the song in both players simultaneously.
Select the "Sync Rate" button in the left player, and slide its lever to the left side of the bar. (The lever in the right player should also slide. This action disables the right player, so all actions can be taken through one player.)
Screw the song. Click the "Play" button in the left player. When the song begins to playback, use the Sync Rate lever to change the pitch of the song. Select "StopBoth" to begin working on the chop.
Select the "Style 2" button, which is a specific cross-fading style that will be in the middle of the audio editing application. (This is directly below the delay interval number.)
Click the "Play" button to begin playing the song back, so you can find the delay interval for the chop. (The delay interval enables the song to skip certain beats for the chop effect.)
Move the plus or minus lever to increase or decrease the speed of the chop. (See Tips section for help with locating the chop for your particular song.)
Click the bar below the "Style 2" button to chop the song. Hold and release the button where you want the chop to take place. (The bar will move from side to side with the Style 2 cross-fading effect. This indicates that the chop is switching between both players to cut up the song.)
Click the "REC" button at the bottom of the application when you are ready to create and record your own mix. Then you can save the recorded version of your screwed and chopped song.
