For more stops, stack instances of this patch.
Use Pipe Organ Trumpet Pedal as the pedal patch, and combine with a fundamental flute instance of this patch.

The above demo is 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.

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.

Configure the patch

Use the macro controls in the UI of Surge XT, or map your controller to use CCs 41−48. By default, my Sticky Fingers touchscreen web app has keyboards and macro sliders for Surge XT over MIDI.


Macro	MIDI CC	Name	Description
1	41	Attack	How quickly the air speed builds up.
2	42	Fundamental	8' A boost to the fundamental frequency.
3	43	Swell close	Selectively dampens an octave above for some ranks.
4	44	Stop 2	4' flute
5	45	Reed 2	4' reed
6	46	Stop 2b 2	2' flute
7	47	—	Not used
8	48	Reverb	Large room ambience
