In Surge XT, navigate to John Valentine > Keys > Pipe Organ Flutes and Reeds.
The main sound comes from a resonating noise source, similar to the way pipe organs work. Reed stops and extra flutes at 4' and 2' are available, and a swell control dampens octaves above the fundamental.
Recommended for use with a well temperament, rather than 12-ET.
|1||41||Attack||How quickly the air speed builds up.|

This from a decently-arranged old MIDI file, adjusted for pace, dynamics, stops, and playing style. Each of the 13 tracks is a Surge instance, with its stops configured to match the intended purpose. Larger pipes like 16' and 32' are scene-transposed with patch tweaks.
