Key follow: These sliders affect the intensity of the envelope generators according to how high up
the keyboard a particular key is pressed. High settings will cause higher keys to follow a more intense
envelope profile.
CAUTION: If you reduce the SJ-2 envelope’s SUSTAIN amount, the peak of the envelope’s output can actually
rise - the SJ-2 attempts to recover overall volume level . This helps to offset any loss of volume which the
patch might incur due to the reduced sustain setting.
However, at very low sustain settings, the effect can be quite dramatic.
If an envelope which is controlling volume is subject to a reduction in sustain level,
PLEASE PROCEED CAUTIOUSLY
in order to protect equipment and prevent ear damage.
Self-Compensating Sustain Level
Please note that the maximum output from either of the SJ-2’s envelopes exceeds the highest cut-off frequency
setting (all frequencies allowed through) by a wide margin. This is deliberate and can be used to refine a
cut-off envelope profile around its peak, as shown below:
Max cut-off
Max cut-off
Envelope to filter slider set so that the
maximum envelope output is less than
max cut-off (all frequencies allowed through)
Envelope to filter slider set so that the
maximum envelope output exceeds
max cut-off.
I n the second example, because the peak is ‘clipped’, the filter remains fully open for a longer period
and this will have a dramatic effect on the sound.
Please note that adding filter cut-off manually, in addition to envelope output, will further intensify this
effect since the two sources (cut-off slider & envelope output) are simply added together.
