Master Series stops are based on close sampled
recordings from various different organs by different builders. All stops
are recorded and edited according to our carefully developed formulas which
means that stops from different instruments and builders can be selected to
create instruments to virtually any specification desired. Obviously, there
are limits to this and it is obvious that one should not try to incorporate
stops from Silbermann with say those of Hope Jones, so one should perhaps
add that the various groups of stops are chosen from similar instruments
from the same tonal schools and periods.
Why should we wish to do this ?
Some organs, even those made by the same builder to the
same scales, have examples of stops that are better than others. A
particular stop or chorus of stops from church "X" may be finer than that
from church "Y" for any number of reasons.
Some organs have stops where certain areas of the stop
are excellent but other areas may not be so good. This can be as a result of
a number of factors including bad positioning, damaged pipes through years
of tuning or pipes that have ceased to speak at their best as a result of
age and so on. In other cases, ambient problems such as a nearby blower or
excessive action noise can render an otherwise excellent source unusable.
Some organs have very fine examples of individual stops
but mundane examples of others. In some cases various combinations may sound
delightful but the overall effect of the instrument as a whole may not be so
Some organs are lacking in certain desirable stops
either because of their original design at the time they were built or as a
result of lack of funds or space.
Our techniques allow us to be able to "re-model" stops
and create new ones from existing ranks. This extends to creating stops of a
different pitch from the original so that say a 4' Flute could become a 2,
2/3' Nazard for example. To a limited extent this can be done by pitch
shifting since dry samples do not contain an acoustic component as such but
in most cases this is not successful and the pipe samples are re-pitched
within the context of the stop so that for example bottom G on a 4' Flute
becomes Bottom C of a Nazard and so on.
It is of course possible to be very lucky and merely
introduce an extra, modified or replacement stop into a scheme with little
more than a rough adjustment of overall balance and have it all work.
Likewise, it is possible to tack on a new bass octave of one stop and it may
blend in with the existing remainder of another stop with little adjustment.
However, it is more likely that considerable time and effort will be
required to achieve the right results in both cases.
Master Series stops are supplied in a format that is
very similar to real pipe organ stops in order to allow for as much
flexibility as possible. All of the basic preparation has already been done
but unlike sample stops prepared for a specific instrument, the stops have
not been "sanitised" or specifically tailored to work within a given
specification. They are therefore capable of having considerable and extreme
adjustments applied to them.
