Structure is a full-on sampler that integrates seamlessly with your Pro Tools software. It comes with an excellent library of sounds, and is also compatible with most native sample libraries. On top of this, it enables you to drag and drop regions directly into it from the Pro Tools arrange page for immediate playability.
There’s also an integrated sample editor, while the inclusion of six Smart Knobs that can be freely assigned to your favourite parameters makes it a much more immediate and playable instrument.
In summary, Structure is both a simple, easy-to-use sample player and a mind-bogglingly complex sound processor with a huge range of expression options.
