SLGain is a gain/volume knob with the goal of being both simple and versatile at the same time. It has three main parameters:
1.) gain control: the amount of boost or attenuation applied to the original signal, in dB.
2.) minimum gain: the minimum value the gain control can reach, in dB. By default this is -12dB, but can be changed to any value between -96dB and -6dB.
3.) maximum gain: the maximum value the gain control can reach, in dB. By default this is +12dB, but can be changed to any value between +6dB and +48dB.
To change controls 2 and 3, simply click them and enter a new value manually; or click and drag the dotted area.
To add another layer of flexibility, all of parameters can be automated.
