Hello there,
Have you tried visiting the German page on Content organs, provided by a German shop? It provides a recital of organ works played on various models of the brand. The link is
www.sakralorgelwelt.de/content/. There, find the button called Klangbeispiele on the left, and you will see a long playlist.
Generally speaking, from what I know, the company can offer different voicing, that is, English or Continental. However, their ordinary voicing in is in what organ literature would call the North German Baroque tradition to the degree of sounding like some Danish and certain other organs in Germany. In the past, there were ancient organs in Eastern Germany, that sounded similarly. For the pipe organ equivalent, the digital brand seems to emulate the Marcussen and Son's pipe organs produced in Denmark. The characteristics include forceful, articulate principals, and high-pitched mutations such as the 1' and 1 1/3' are made available for use. Also, the mixture and cymbel are unique, when compared to South German Baroque organs. Overall the voicing is lean and clear-cut, devoid of excessive fat lower harmonics.
I disagree with certain unfair comments I've read about the voicing. If you get a CD that features the old organs of Denmark, you will get general picture of the tonal quality which is extremely well emulated by Content. More often, we hear sounds produced by other digital organs in the South German tradition.
Someone had asked about a comparision between Content and Johannus. The latter featured a similar voicing more than 10 year's ago, but it seems to have altered its voicing in its more recent lines.
Also there are a few Content organ sound excerpts one can find on youtube.
Regards,
Felix
