When designing an organ, one of the variables needing consideration is piston layout. Annoyingly, there is no definitive specification.
Clive Sidney has come to the rescue by providing a suggested British piston layout . Click on the link below.
Bear in mind that we use a piston spacing of 28.5mm instead of the suggested 32mm which yields a greater piston density, particularly useful when using touchscreens. This gives 29 piston positions across the keyslip, combination setter at position 0, the first divisional at position 12 and general cancel at 29.
Romsey OrganWorks can create any piston layout including user defined nomenclature.
