Input Control Dialog
Most of the controls in the dialog perform functions that could be performed by the standard Windows mixer. However, use of that mixer is strongly discouraged. It is not capable of being calibrated. Worse, it allows you to mix together multiple signals in arbitrary proportions, which renders Daqarta's calibrated axes and readouts pretty much useless. And even if you don't care about exact calibration, it is very difficult to repeat the same settings on subsequent sessions. So, use the mixer for its intended purpose, in entertainment applications. Use the Input Control Dialog with Daqarta.
At the top of the dialog is the name of the Input device in use. If you have more than one input device on your system, you can change this from the Input Device select in the Start Preferences dialog. (Note that changes won't take effect until the next Daqarta session.)
The top control in the dialog is a duplicate of the toolbar Input toggle, and likewise is activated by ALT+I.
Below it are Left and Right channel toggles. You must have at least one of these active in order to toggle Input on.
Then there are up to 8 line selects per channel, depending upon your sound card. You may select only one per channel; the rest are automatically deselected and muted to prevent spurious input signals.
When you select an input line, the Line Level control below the select buttons will be updated with the selected line name and the current level. Below the Line Level controls are Master Level controls. Both levels are in 'steps' by default, but after your card is calibrated the 'dB' button at the bottom becomes enabled to allow you to see the actual dB from each control, as well as the total dB for each channel.
InputDlg=1 opens the Input dialog, InputDlg=0 closes it, and InputDlg=x toggles between open and closed.
Note that you don't need to open the Input dialog to activate any of its controls via macro commands.
