32 SELECT PROG
USING THE S3200 S EFFECTS
These days, effects are as important a feature of a sound as the filter settings
or envelope settings and when you load a sound from disk you want to be able
to recall it with its effects every time you load it. The S3200's two internal
effects sections allow you to do this.
When you turn on the S3200, you have two effects sections I3B13 and
la in is an abbreviation of REVERB and gives you access to 50 reverb effects
and the U S H selection gives you access to 50 effects comprising multi-tap
echo, stereo chorus/flanging, stereo pitch shift and a single delay line with
modulation. These may be used in parallel so that, in a multi-timbral or
layered setup, some programs may be send to one section whilst other may be
sent to the other. It is also possible to send one program to both effects
sections simultaneously. These 100 preset effects are made up of five basic
effects types. These are:
REVERB - This allows you to select from several different types of reverb
from long, spacious halls to tight rooms.
ECHO - this is a three tap delay line. In other words, instead of having just
one delay setting as most units do, you have three and each delay can be set
separately each with its own feedback and pan position. This allows you to
create a wide range of delay and echo effects from straight single delays to
ping-pong echo through to complex multi-tap echoes that can simulate the
echo effects only offered by older tape echo devices but without the wow and
flutter and tape hiss, of course!!
CHORUS - there is one all purpose effect that covers every type of modulated
delay effect from mild, shimmering chorus to flanging effects. The algorithm
used for these effects is very complex and uses four delay lines that are
modulated by a low frequency oscillator (LFO) but the modulation phase angle
for each delay line is different. This allows you to create rich, swirling
stereo effects and also eliminates the unpleasant cyclic repetition you get
with chorus and flange units that use only one delay with one LFO.
PITCH SHIFT - this is a stereo pitch shifter that allows you to transpose a
sound up or down by as little as .01 of a semitone for subtle detune effects to
50 semitones. There are two pitch shifters and each one has a delay line in the
feedback loop allowing many interesting special 'spiral' and arpeggio effects
to be created.
DELAY - This emulates a single delay digital delay line for long delay effects.
Modulation is also provided for flanging effects.
On the S3200, you have two 'EFFECTS FILES' and each contains 50 effects.
The effects in each of these effects files can be freely assigned to any program
number so that one effect can be used on several different programs. For
example, you may have a strings program, a brass program and a piano
program with the program numbers 1, 2 and 3 and you may wish them all to
share the same chorus effect. In this case, all you need to do is assign the
appropriate chorus effect to programs 1, 2 and 3. Of course, every program
can have its own unique effect if you wish.
Similarly, a group of programs that have the same program number may
share one effect so that, in a layered, split or multi-timbral setup, you may
assign an effect to all sounds 'globally' and each program can have its own
effects level using the SEND parameter described in the mixer section above.
