Members of the Yahoo VTPO Group spent some time in 2012 learning how to sample their theatre pipe organs, and a mostly Robert Morton based theatre organ had its ranks recorded, and some ranks from another theatre pipe organ were also recorded, as part of this experience. I was given those recordings and have done the noise reduction, tuning, looping, etc..
These samples have been released as the Freedom Morton Series for Hauptwerk, which consists of three virtual organ specifications:
Freedom Morton 2/6 for Hauptwerk
Freedom Morton 3/10 for Hauptwerk
Freedom Morton 3/17 for Hauptwerk
The samples are also available in soundfont format for use with for jOrgan:
jOrgan Freedom Morton 2/6 Theatre Organ
jOrgan Freedom Morton 3/10 Theatre Organ
I also created a Miditzer 216 soundfont using these samples, which is available from:
The samples are in 16-bit 48khz Mono (panned to Stereo positions in the sample set), and the sample set uses recorded tremulant samples. They were recorded just outside the swell shades, so the organ sound is 'semi-dry' and may benefit from added reverb. For those who like the small organ studio feel, the samples are probably just right as they are.
