Pitch shift setting

Pitch shift— This sets the change in key or pitch of the entire track. You can adjust this parameter hy pressing the -I- and — keys on the numeric keypad on your keyboard after first clicking on the track header of a track. 

The Root Note is the key of a loop. This property of a track can be changed on the Stretch tab in the Track Properties window of Loop and Beatmapped type tracks. The Root Note allows a track to be automatically pitch shifted to match a project or the key changes that occur in a project as a result of Key Change markers. Setting the Root Note to Don t Transpose prevents this from happening. Any time you want a loop to be protected from key changes, you should select Don t Transpose. You ll notice that most percussion and drum loops have Don t Transpose as a Root Note, as well as some vocal loops and, especially, spoken word loops. 

The purpose of setting the key of a loop or Beatmapped file is so ACID can automatically pitch shift the track to fit the project key or follow project key changes (see Chapter 4). This is a very convenient feature, but it depends on accurate determination of the key as saved to a media file. 

Pitch shift allows you to adjust the key, or pitch, of the MIDI file without setting a root note on the Voices tab. The shift is measured in semitones, or half-steps, and is limited to +/ —24. The changes made here are reflected on the Track Header. 

The federal government has developed regulatory standards and guidelines to protect workers from the potential health effects of other coal tar products in air. OSHA has set a Permissible Exposure Limit (PEL) of 0.2 milligrams of coal tar pitch volatiles per cubic meter of air (0.2 mg/m3) in workroom air to protect workers during an 8-hour shift.
