Realistic
And Convincing Bass
Copeman Hart have more experience than any other electronic
organ company of obtaining superb organ bass at minimal
cost. This is due to our ability to design bass
enclosures to form part of the building, where desirable,
and be made from comparatively inexpensive materials
-- we design and provide drawings for architects or
builders to work from, and this approach has proved
far more successful and economical than installing quantities
of small boxes which combine to give a rather 'boxy'
bass without true and adequate fundamental.
Voicing On Site
The voicing process, which is carried out entirely from
within our own resources, is performed on every Copeman
Hart organ: we also have the unique ability and
experience to voice sensitively and musically in any
required style. This is carried out by every pipe
organ builder of repute, but is greatly neglected by
many producers of electronic organs. The
setting of a few volume and tone controls does not constitute
'voicing'.
Our uniquely flexible digital voicing process means
that any stop can be changed in any manner desired on
site, dictated by acoustic requirements or even the
changing thoughts of the consultant. For instance, the
harmonic structure of each stop, throughout its compass,
is addressed and can be changed. This approach
is fundamentally different from that obtainable with
'sampled sound' organs, where much simpler controls
will affect far fewer parameters, and even then may
interact to the detriment of other stops. We can
address the pitch of each stop, many variables in the
attack and decay, and that all-important component,
the 'steady state', which, of course, is by no means
steady in a pipe organ: nor is it in ours, and
we are able to pay great attention to this without the
use of artificial 'chorus generators', as well as to
the more common details such as harmonic content and
the amount and nature of 'chiff'.
Just as with pipes, good voicing can only be achieved
by a genuine musical artist: it is well known
that there are good pipe organ builders, but also indifferent
ones. Although a computer is used as the interface
between the voicer and the organ, replacing the traditional
tools of the pipe voicer, a computer expert is not necessarily
a good voicer: Copeman Hart, however, have --
possibly uniquely -- masters of the art, with musical
and electronic qualifications, who not only understand
the technology but can create from essentially sterile
digits an organ of artistic integrity.
Amplifier And Loudspeaker Systems
'Full organ' is never an anti-climax on a Copeman Hart
instrument; we will not over-amplify a small instrument,
just to make it fill a large building -- and, conversely,
we would never condense the outputs of 60 or more stops
to emerge from only a few loudspeaker channels. Whilst
the technical reasons for this may not be apparent to
organist or listener, all are unanimous in the praise
they give to the end result. Apart from the unique
quality of the voicing, and the fact that each stop
has a 'C-side' and a 'C#-side' as occurs in the layout
of practically every pipe organ, our practice of spreading
the organ amongst sometimes as many as 38 separate amplifier
and loudspeaker systems -- each system containing bass,
mid-range and treble units -- gives us the freedom to
arrange departments of the organ in a manner very similar
to the layout of a pipe organ.
