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.

Printing and saving with PAZ
To print a PAZ reading, select Print... under the File menu.
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.

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.

Windows
Save a PAZ screen by pressing the Print Screen key. 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.
