OSCILLATOR CROSS MODULATION (4)
Yet another factor which can affect the pitch of oscillator 2 is the output from oscillator 1; that is oscillator 1’s
waveform - when at the top of its cycle osc 2’s pitch will rise and when at the bottom of its cycle, osc 2’s pitch
will fall.
Clearly this pitch fluctuation will be very fast indeed and will serve to provide a timbrel effect rather than
discernible pitch variance.
The left hand cross-mod slider simply sets the extent to which osc 2 is modulated by osc 1. The right hand
slider controls the extent to which cross modulation responds to envelope 1 (please see the section on
envelopes later in the document.)
OSCILLATOR MODULATION RESPONSE (5)
As mentioned earlier, a number of factors can affect oscillator pitch besides the oscillator pitch controls
themselves.
These other factors are said to ‘modulate’ the oscillators’ pitch - modulate simply means ‘change’, and while
the keyboard could certainly be described as a modulator, the term is more commonly reserved for other
parts of the synth’s architecture which can affect pitch - lfo’s and envelopes in particular (these will be
defined later in the user guide.)
The SJ-2 works as follows: parts of the SJ-2 architecture which can control pitch have their own sliders to
set how much pitch modulation will occur, and this will be the same for both oscillators.
In addition, though, the way the oscillators respond to the modulation can be set individually for each
oscillator from within the oscillator section, using the switches labeled (5) above.
Using these switches, you can set each oscillator to either respond positively or negatively to the
modulation, or not at all.
This may seem a little unnecessary, but it’s actually a really neat feature and once again, is
particularly useful when the oscillators are sync’ed.
