Pulse width & pulse width modulation are so important that the SJ-2 has a section

dedicated to them:

The controls labelled ‘PW’ set the pulse width for each oscillator.

If the oscillator is set to any wave other than pulse wave, the settings here will have no effect.

The actual Pulse width can be made to fluctuate around the point set by the ‘PW’ slider, by an amount

set by the ‘PWM’ slider - this stands for ‘pulse width modulation’.

And what is the nature of this fluctuation? That is set by the slider labelled ‘SPD’ and the switch next to it.

THE SWITCH:

(Please refer to later sections on LFOs and envelopes.)

Each of the SJ-2’s oscillators has a dedicated LFO specifically for pulse width modulation.

With the switch set to ‘LFO’, the dedicated LFO will modulate the pulse width at a speed set by the ‘SPD’

slider.

With the switch set to ‘EV1’, envelope 1 will modulate the pulse width.

With the switch set to ‘KYBD’, keyboard tracking will modulate the pulse width.

With the switch set to ‘SYNC’, oscillator 1’s LFO will modulate the pulse width of both oscillators.

The two remaining switches set the polarity of the pulse width modulation.
