MultitrackStudio features a large number of built-in high-quality effects. In addition VST/AU plugins can be used.
Effect Selector (Pro edition)
Effects are reached via Effect Slots. Effects can be selected by clicking the slot's down arrow (or by right-clicking the slot). The Effect Selector contains all native MultitrackStudio effects, VST/AU plugins, Convolutor impulse responses and effect presets. A search text can be typed to filter the list. VST and AU list items have invisible tags so you can use 'vst' or 'au' search terms to hide the other type of plugin. When an effect's user interface is visible you can press the F3 key (Windows) / Option-Command-F (Mac) to pop up the selector list. It remembers the search text, so you can try the next effect which matches the search text easily.
Clicking the slot's button will show the effect's user interface. All effects have a Bypass button. If the effect is not actually active (it's either bypassed or its controls are in neutral position) the text in the effect slot's display appears dimmed. Inactive effects do not use any processing power.
Effects can be moved using drag-and-drop, keeping the Ctrl key (Windows) / Option key (Mac) down while doing this will copy the effect instead of move it. Adding or removing effects can be done while the transport is running.
The following effects are available:(*): Pro edition only
Presets can be loaded or created using the Presets button which appears on the effect's user interface. Most effects come with built-in presets.
Controlling the Transport
You can use either the keyboard or the mouse to control the transport while an effect's user interface is on screen. In particular the Alt+Left Arrow (Windows) / Command-Left Arrow (Mac) key combination will be useful when setting up effects. Some VST/AU plugins can gain "keyboard focus", which makes it impossible to control the transport using the keyboard. You can click the righthand part (the "MultitrackStudio part") of the plugin window to restore keyboard focus.
