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.

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. 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.)
