AGC AGC stands for Automatic Gain Control. When AGC is enabled, notes played at low volumes are automatically boosted and therefore more apt to trigger recording. RCT has its own software AGC which works just fine on computers that don’t have hardware AGC. On older Mac PowerBooks, hardware AGC is enabled in Ch2 and CE at all times. AGC is optional in PAZ and should be turned off only to allow for unusual situations such as noisy environments, or to give you more control over sampling volume. RCT 1.1 and earlier did not make use of any hardware AGC. AGC AGC stands for Automatic Gain Control.

Currently, RCT does not save PAZ readings with the normal Save... command under the File menu. Instead, you can save a picture of a PAZ reading by creating and saving a picture of your Computer’s screen on your hard drive.

Instead, you can save a picture of a PAZ reading by creating and saving a picture of your Computer’s screen on your hard drive. Macintosh Press the key combination Command-shift-3. The Mac will make a Ka-Click sound (like a camera shutter) as it takes the picture. A “screen shot” of whatever is currently displayed on your computer’s screen will be saved to your hard drive (at the root level) and named “Picture 1” or a higher number if necessary. You can view these screen shots in Simple Text or most graphic applications (where you can edit them too.) In the Finder, you may wish to re-name this PAZ screen shot (e.g., “Steiger ser# 12345”) and move it to another folder. Macintosh Press the key combination Command-shift-3.

On laptops it may be named “PrtSc” or “PrntScrn”. This key is usually located near the F12 key. Next, and before doing anything else, open a paint program such as Microsoft Paint and press Ctrl-V. After pasting the screenshot into MS-Paint, you can edit, save, and print the picture. Windows Save a PAZ screen by pressing the Print Screen key. On laptops it may be named “PrtSc” or “PrntScrn”.
