This disposition is the joint work of Chris Pearson (sampling/soundfont) and Dries Nelemans (disposition/graphics). This work is covered by the Creative Commons Attribution-Non Commercial-ShareAlike 3.0 Unported (CC-BY-NC-SA 3.0) license.
Golcar Providence Methodist Church is located in the rural area of the Colne Valleynear Huddersfield, West Yorkshire, England at the foot of the Pennine hills. The church organ is about 100 years old and has not had any modifications to it since it was built by Peter Conacher (Old Firm) of Huddersfield. It has tracker action to the 3 manuals and pneumatic-tracker action on the pedals. The organ is tuned to A=452Hz which is known as the “old Philharmonic high pitch”. The disposition caters for a number of other pitches. The organ has a balanced swell pedal and there are three composition levers operated by the foot for each of the Swell and Great manuals. The compass is 91/30 notes which has been extended to 96/32.
The sound samples were recorded over a period of two days, sampling every sounding pipe. Some pipes mainly on the pedal 16 foot Diapason and a few on the Bourdon ranks no longer sound, with a few on the manuals not sounding correctly. The façade pipes are part of the No.1 Open Diapason rank, which have been included in the soundfont at almost one sample per note. Sampling was done using a Tascam DR-05 Linear PCM recorder at 48 KHz in stereo at a distance of 2 metres from the console. The samples were processed with Audacity to split into left and right channels and cleaned with Spear. They were then recombined into stereo in Audacity and converted to 44.1 KHz and looped using Endless Wave. The sf2 file was compiled using both Viena and Polyphone. The number of stereo samples in the soundfont ranges from almost one per note as previously mentioned to one per six notes on the compass extension. A combination sequencer, memory, divisional pistons and a Great to Pedal reversible coupler have also been included which are not on the original organ. A flac sound file of the reverb is included for those using convolution reverb.
Hybrid Conacher VPO v1.0 for jOrgan 3.20 and higher
This disposition is the joint work of Dries Nelemans (disposition/graphics), Chris Pearson (sampling/soundfont) and Michael Tinsley (additional samples). The work is covered by the Creative Commons Attribution-Non Commercial-ShareAlike 3.0Unported (CC-BY-NC-SA 3.0) license.
This disposition is based on other organs built by Peter Conacher (Old Firm) Huddersfield and uses the Golcar organ as its base with some extra ranks, additional modern accoutrement and extra couplers, etc. The mono samples for some of the extra ranks, courtesy of Michael Tinsley, have been stereo panned in a hollow format in Polyphone to match the original Golcar stereo soundfont. The extra pedal ranks have been panned to either side of the organ pipe chamber, as the Golcar organ ranks are in reality. The disposition caters for those with one expression pedal. This can be set to operate either the swell, choir, swell and choir or general crescendo.
