The vibrato for this program is controlled by the
LFO RATE control. Using a Modulation pedal wilJL
change the amount of vibrato.
These programs are four different types of key
board instruments. A Filter pedal works well on
A2.
"X-MODff is the modulation of QSC 1 by OSC 2. This
creates non-harmonic overtones which give X-MOD
its "klang" tone.
The "delay11 in this patch is the modulation of the
filter that is not present until the key is released,
The OSC 2 DETUNE can be used to change the tone
quality of the sound in this program.
The filter is modulated by the LFO at its slowest
speed. The HOLD feature of the OB-SX may be put
to good use on this program. Experiment with
different settings of LFO RATE, ATTACK, and DECAY.
The Modulation Pedal will control the range of the
filter sweep.
These are two examples of extreme modulation. In
BC1 the LFO Square Wave modulates the Frequency of
the Oscillators by a fourth; in AB8 the LFO Sine
Wave modulates the Pulse Width of the Oscillators
by such an extreme amount that the sound actually
disappears. On both of these programs, the LFO
RATE controls the speed of the modulation.
The Oscillators are tuned in fifths in this patch.
The speed of the Portamento is controlled by the
PORTAMENTO control. After the sound peaks, the
Square Wave Modulation of the Filter takes effect.
The speed of the modulation is controlled by the
LFO RATE control.
This patch is best played in Down Octave transpose
and at the bottom of the keyboard.
These are five distinct synthesizer programs. All
five programs work well in UNISON and with a
Filter pedal. Changing the Envelopes can also
vary these sounds greatly.
