Generator Volume/dB Slider Button

Macro : GenVolDlg

This control is the small button between the Left and Right volume controls, labeled 'Vol' on an uncalibrated system, or 'dB' after calibration (if Use dB is set). Besides serving as the label for the volume controls, it also opens a dialog with slider controls. There are separate dialogs for uncalibrated Vol mode and calibrated dB or User Units mode.

Note: If your sound card uses a custom mixer that denies access to Daqarta, the volume controls are disabled here. You must make all volume changes with the custom mixer, and they will not be stored in Daqarta setups.

You may find sliders more convenient than simple edit controls, especially for uncalibrated operation. In that case, there are separate sliders for Master and Wave attenuators, whereas the main Generator edit controls only affect the Wave settings.

Also, the slider dialogs provide Track options to allow the Left and Right controls to be locked together, such that either one affects both. If enabled, Track stays in effect for the main edit controls as well.

Near the bottom of the slider dialogs are Auto and Mute buttons. Auto is a convenient duplicate of Generator Auto-Mute in Edit Menu - Run Preferences. Mute disables the output sound without changing the visible volume control settings.

The Auto and Mute buttons will be disabled if your sound card does not support the Mute operation.

Note that you can use the F9 function key to open the slider dialog at any time, including over any other dialog, to allow quick volume adjustments without having to close and re-open whatever you were working on.

• dB Slider Dialog

Macro Notes:

If the main Generator dialog is open, GenVolDlg=1 opens either the Volume or the dB slider dialog, depending on the Attenuator Options settings (and whether your system is calibrated). GenVolDlg=0 closes the dialog, and GenVolDlg=x toggles between open and closed.

Unlike the manual F9 function key, GenVolDlg will not open the slider dialog unless the Generator dialog is open, but it will open over any Generator Stream dialog or sub-dialog.
