Synth Volume (Left and Right)

Controls: Edit Menu >> Synth Controls >> Volume
Macros: SynthVolL, SynthVolR

These controls only show volume step number, not dB. Any calibration data is ignored. Steps range from 0 at maximum loudness to increasingly-negative integers.

These controls are duplicated in the Pitch-to-MIDI dialog. See the MIDI Volume topic for macro and MIDI Changes script information.

Note that on Windows Vista and later these controls actually operate on the Master Volume, and both Left and Right will always be the same.


Windows XP and Win9x:

On XP and 9x, Left and Right track by default, but you can toggle the 'Vol' button between them to unlock that tracking. When the button is down the Left and Right controls are independent.

Also on XP and 9x, some sound cards may not have Synth volume controls, in which case the controls here will be disabled. Some cards may have only a single control for both channels, in which case the Right control will be disabled.

Synth output and Generator (Wave) outputs both feed into the same Master Out attenuator on XP and 9x. If you use the Synth and Generator at the same time, you should make sure that Use Vol Steps is selected in the Generator Attenuator Options dialog. The Generator Vol slider dialog will then show separate Wave and Master sliders. (In Use dB mode the Wave and Master controls are coordinated to provide a single control with a much larger range for each channel.)
