Detailed Description

Projects an inclusive MIDI pitch range onto piano-roll rows.

Screen y increases downward, so the highest pitch owns the first row. A pitch projects to the center of its row without clipping, so renderers can cull notes outside the visible range. Inverse lookup returns the visible row that contains y and clamps outside input to the visible pitch endpoints.
