7.2.3 ENSEMBLE Panel
In order to make full use of the parameters on this panel you need
to understand how a string ensemble effect works. The following
paragraph aims to provide you with the necessary know-how to
successfully tweak your own string timbre. Be careful with these
settings since there tends to be a thin line between a rich ensemble
and something completely unimpressive.
•
The Eminent/Solina type string ensemble effect is a variation
of the classic chorus effect.
•
A typical characteristic of a real string ensemble is that the
individual musicians are never completely in tune even when
playing the same note. This can be simulated by means of
modulated delay lines. By varying the delay time of a delay
line the pitch of the notes played is also affected. You might
know this phenomenon if you ever owned an old tape deck or
record player with an
unstable playback
speed.
•
There are three delay
lines. The delay time
of each is modulated
at the same time by
two sine-shaped low
frequency oscillators.
•
The trick is that there
are actually only two
of these sine oscil-
lators for all three
delay lines. In order
to create a different
modulation signal for
each delay line two
phase shifted sine
waves are deducted from each oscillator with an offset of 120
respectively 240 degrees from the original signal. The three
modulation signals from each oscillator are thus equal in
shape but their phasings are evenly distributed around the
360 degrees of the full circle. This results in a very
