Pipe organ online
Every note is a recording of an English church organ's open diapason, the warm, round stop at the heart of hymns and wedding marches. The lowest notes come from the pedal pipes, so deep chords have real weight, and every note was measured and tuned to the exact pitch.
A pipe keeps sounding while its key is down, and so does this one. On a velocity-sensitive MIDI keyboard a light touch plays the quieter take and a firm one the full sound; your computer keys play the full one.
No organ, no church and no download. Set the reverb to Cathedral for the full echo, record a hymn or a spooky chord, and keep the WAV, which is made on your own device and never uploaded.
