Sensation is not a window, but a production. It is an odd production, in that its production is not itself produced. Sensation is involuntary presentation by ineradicable contents. The contents are immediate—this is nothing informative since all presentations are immediate. It is wrong to say that a concept is present as a presentation because it presents nothing. (Which is why it can function in general logic and have the strange Pauli-violating properties of concepts, They are pointers to flattened rules. The meaning of a concept is always either the product or the process of schematizing.)

Sensation carries its own form. That is, the subject-side of reception has a certain constant feature. Kant calls this the form of sensible intuition. But this is misleading, because the “form” in this case is formless. He should have called it: form-that-appears-after-synthesis. Kant’s forms of intuition are actually kinds of chaos. They are kinds of external separation of the basic sense atoms. They are ways-of-plurality that are pre-formed by determining the way of separation that conditions and enables the plurality.
