Low Frequency Oscillator
LFO Destinations
Just like the SJ-2’s main oscillators, the low frequency oscillator (LFO) creates waveforms.
You can select from four different wave-shapes; sine, triangle, square and random.
Unlike, the main oscillators, the LFO is not influenced by which key has been depressed;
the frequency is controlled by the slider labeled ‘RATE’ in the LFO 1 section and it can go
down to sub-audible frequencies. The purpose of the LFO is to provide a cyclic control
output and it can be sent to various places, in a similar way to the envelope generators
discussed earlier.
The slider labeled ‘DELAY’ will cause the LFO output to build from nothing to its full amount over a period of time, rather like
the attack control in an envelope generator.
The SJ-2 actually has two flexible LFO’s; the second one appears in the SJ-2 Control Section, described later.
(In addition, there are dedicated LFOs for each oscillator’s pulse width, bringing the total to 4.)
The SJ-2’s second LFO can only provide a sine wave and has no delay function. It can control either pitch or filter cut-off.
The important thing about LFO 2 is that its intensity is scaled by modulation wheel data .
Other Programming Features
OSC MIX
: this allows you to adjust the volumes of t
he SJ-2’s main oscillators. Note: if you find that the SJ-2
filter is distorting at high res settings, please try turning
these volumes down a little.
ENV RESET
: not currently implemented .
