At moderate values you can get some pleasant phasing
effects. High values can make the oscillators sound completely
out of tune with each other – also a useful effect when used in
the right context!
SYNC
When this function is active (while using “Classic” oscillators),
oscillator 2 is synchronized to oscillator 1. Look up Sync in the
glossary if necessary. One popular use of Sync is to create an
effect similar to a bandpass filter with a lot of resonance and
some distortion:
Restore ROM-A126 and press the SYNC button – the rhythmic
beating between the two oscillators is eliminated. Select oscil-
lator 2 and play some notes while sweeping the SEMITONE
control from slightly below centre to maximum. If you would
like to hear oscillator 2 in isolation, turn the OSC BALANCE
knob (you will find it in the MIX section) up to maximum. If you
leave SEMITONE at certain fixed positions, you can get some
interesting static overtones.
Tip: If a sound ever gets annoying, filter it!
OSC 3 ON
Although the third main oscillator may appear to have all the
same options as the other two, it is highly dependent upon
what is currently happening with oscillator 2:
Restore ROM-A126, select oscillator 2 and change SEMITONE
to +7. Press the OSC 3 ON button (its status LED will light up)
and select oscillator 3 (both LEDs above the OSC3 ON button
are lit). If you now try changing SEMITONE, you won’t notice
any effect. This is because oscillator 3 is currently a slave to
oscillator 2. Try changing WAVE SELECT from Slave to Saw,
then adjust SEMITONE to +4.
Tip: When oscillator 3 is active, you can control oscillator 3 vol-
ume from the panel via SHIFT + SUB OSC VOLUME.
MONO
This button selects whether the entire sound is polyphonic or
monophonic (there are several mono key modes available).
Although your Virus is polyphonic at heart, monophonic
sounds can be particularly expressive, especially when porta-
mento (coming shortly) is applied.
Tip: To step through all Key Modes, hold down SHIFT before
pressing the MONO button.
