The Modulation Envelope
The Modulation Envelope parameters let you control how certain parameters, or
destinations, should change over time - from the moment a note is struck to the
moment it is released again.
The destinations you can use are:
• Pitch
• Filter frequency
Parameters
The following are the available controlling parameters:
D Attack
When you press a key on your keyboard, the envelope is triggered. The at-
tack parameter then controls how long it should take before the controlled
parameter (pitch or filter) reaches the maximum value, when you press a key.
By setting attack to a value of “0”, the destination parameter would reach the
maximum value instantly. By raising the attack parameter, the value will in-
stead slowly “slide” up to its maximum.
D Hold
This is used for deciding how long the controlled parameter should stay at
its maximum value before starting to decrease again. This can be used in
combination with the Attack and Decay parameters to make a value reach its
maximum level, stay there for a while (hold) and then start dropping gradually
down to the sustain level.
D Decay
After the maximum value for a destination has been reached and the Hold
time has expired, the controlled parameter will start to gradually drop down
to the sustain level. How long it should take before it reaches the sustain
level is controlled with the Decay parameter. If Decay is set to “0”, the value
will immediately drop down to the sustain level.
D Sustain
The Sustain parameter determines the value the envelope should drop back
to after the Decay. If you set Sustain to full level however, the Decay setting
doesn’t matter since the value will never decrease.
A combination of Decay and Sustain can be used for creating envelopes
that rise up to the maximum value, then gradually decrease to, and stay on a
level somewhere in-between zero and maximum.
D Release
This works just like the Decay parameter, with the exception that it deter-
mines the time it takes for the value to fall back to zero after the key is re-
leased.
D Delay
This is used for setting a delay between when a note is played and when the
effect of the envelope starts. That is, the sound will start unmodulated, and
the envelope will kick in after you have kept the key(s) pressed down for a
while. Turn the knob to the right to increase the delay time. If the knob is set
all the way to the left, there will be no delay.
D Key To Decay
By using this, you can cause the value of the Decay parameter (see above)
to be offset depending on where on your keyboard you play. If you turn the
knob to the right the decay value will be raised the higher up you play, and
turning the knob to the left will lower the decay value the higher up you play.
With the knob in the center position, this parameter is deactivated.
Destinations
The following are the available Mod Envelope destinations:
D Pitch
This will make the envelope modulate the pitch, as set in the Pitch section
(see page 178). Turn the knob to the right to raise the pitch and to the left to
lower the pitch. In the middle position, pitch will not be affected by the enve-
lope.
D Filter
This will make the envelope modulate the cutoff frequency of the Filter (see
page 179). Turn the knob to the right to increase the frequency and to the
left to lower the frequency. In the middle position, the envelope will have no
effect on the cutoff frequency.
