EQ
Equalization can be used to subtly adjust the spectrum of a sound (as we saw in Tutorial 4, Part 2), but it can also be used to create more radical effects. The EQ in RTGS3 can be set up to do either of these.

Locate the EQ interface in the Effects section of the main window and activate it by clicking on its toggle:

Fill both buffers with pink noise at 80% amplitude (refer to Tutorial 0, Part 1 if you don't remember how to do this) and then set the Grain Envelope to a fast attack:
Click the "Generate a Grain" button a few times to get an idea of the type of grain you've just created.

Return to the EQ interface. Click near the middle of the EQ graph and drag the mouse upwards until its setting looks like this:
Click "Generate a Grain" a few times again to get an idea of the change you made to the output sound.
When adjusting the EQ graph settings, you can drag the mouse up and down to set a band's amplitude, or left and right to set a band's frequency. Clicking on the edge of one of the bands lets you change that band's width.

You can also set the EQ parameters numerically in the Graphic EQ Settings window, which you open by clicking the EQ's gear icon. Let's use this window to change one of the EQ band's width (also called its "Q"). Open the window and make the following settings to band 3:
You'll notice that any changes made in this window are reflected in the EQ graph. Click "Generate a Grain" a few times to get an idea of the changes you can make to the output sound.
You might wonder why the EQ settings can be controlled by MIDI, but not by one of the RTGS3 controllers. This is because some controllers can generate unexpected or extreme parameters (such as most of the Generators can). This in turn could cause the EQ to generate very loud output which is dangerous for both your ears and your equipment.
