Understanding the amplifier effects

In the right side of ES2 we have got the Amplifier and Effects section.…So this is the last stage of the signal flow,…because we've got the oscillators, then it goes through the filters, and then it…hits the amplifier and effects.…So in the amplifier we've got the Volume Control.…This is just our master volume, which you can adjust--…(music playing)…--up and down. If you want to reset it, just Option+Click sets it back to its…default setting at 0dB.…Beneath that we have actually a really cool feature. This is Sine Level.…So what it's going to do is this is going to bring in a sine wave from…oscillator 1 underneath whatever sound we have that's happening.…

And it's going to be unfiltered sine wave too.…So it goes directly from the Oscillator into the Amplifier stage.…And the cool thing is we actually don't even need to have Oscillator 1 on.…So if I turn Oscillator 1 off and I turn down the Sine Level, we should have silence.…So I am playing the keyboard now and there's nothing.…So I can bring up the Sine Level.…
