CrX4 User Manual - LinPlug Virtual Instruments

The Envelopes are positioned in each Filter, the Main Section and the
Modulation Section (Gen/Mod Envelope). All six envelopes are exactly the
same. They can be of ADSFR type or of AHDSR type, which means:
ADSFR : Attack, Decay, Sustain, Fade, Release
(classic ADSR plus the sustain can either fade in or out)
AHDSR: Attack, Hold, Decay, Sustain, Release
(classic ADSR plus a Hold phase which determines a time span
between end of Attack and start of Decay).
The Envelope type is switched with the Filter Type button at the top right of
each envelope. This button either reads “...F.“ for the ADSFR or “.H...” for
the AHDSR
Clicking on the Edit button at the right of the Filter Type button opens a
popup menu containing the following functions: “Copy”, “Paste” and “Init”.
The “Copy” and “Paste” functions allow current Envelope settings to be
copied and pasted into any Envelope module. The Init (“Initialization”)
function restores the Envelope module to its default values.
Note: You can copy between different envelopes of a patch, between
different patches (the copy buffer is preserved when loading new patches)
and between multiple instances of CrX4 which are simultaneously open.
Envelope Parameters
Attack
The Attack dial determines the time it takes for the envelope to reach its
maximum value. The range is 0 millisecond to 10 seconds.
If used for Amplitude, it means that the Envelope takes so long to reach the
maximum Amplitude, for the Filters it takes so long to reach maximum
Cutoff (or minimum Cutoff when Envelope Depth is inverted, more about
this in the Filter description).
Hold
If the AHDSR envelope is used, this dial controls the time gap between end
of the Attack phase and start of the Decay phase. In classic ADSR
envelopes these phases are connected, as soon as Attack is finished,
Decay will start. With the Hold parameter however the envelope can remain
at maximum level for a certain amount of time. The effect of that is
