Effects Tabs

The Effects tab is where audio effects can be applied to a session. The average user may not often or ever use this tab, but if you wish to adjust the audio (add an Equalizer, for example), this is the place to do it.
Navigator - Controls location of the focus on the patch window.
Master Gain - The Master Gain is applied after all effects. Mute will fully mute the audio, and Full will place the gain at 100%, which is halfway up the slider. Setting it to the left of Full will lower the gain, while setting it to the right of the Full point overdrives the volume (up to 200%), which will increase the gain but may also lead to distortion.
Dry/Wet Mix - This slider controls how much the plugins affect the audio mix being hijacked. When set all the way to Dry, only the original audio source (before effects are added) is used. As it moves towards Wet, the effects are applied more fully.
Levels - Show the audio levels of audio coming in (In Peak and In RMS) or out (Out Peak and Out RMS). The Clip lights show when the signal's peak value exceeds 0db - above this, distortion will occur. Disable the level meters to save CPU.
Patch Area - The 10x10 grid for adding DSP effects. Simply click a grid space and select an item from the pop-up to insert the effect. Drag and drop to re-arrange. The grid is read left to right and top to bottom.
Plugins - Each plugin has its own editor window, with settings specific to that plugin. For more information, see the "Effects" tutorial for more.
Saving and Opening Patches - AH Pro supports patches, which are groups of Effects plugins and settings. When you have a set of filters which you'd like to apply to other presets, choose "Export Effects Patch..." from the Control menu. To load a saved patch file, choose "Import Effects Patch..." from the Control menu.
