LinPlug Spectral - Manual (Page 100)

All Envelopes can be modulated the same way. Please note that all
envelope times are modulated only once at note start (not
continuously). While this slightly reduces the possibilities
of modulating envelopes its much easier to predict how a
modulation will effect the sound.
Env Attack The Attack Time of the Envelope.
Env Hold The Hold Time of the Envelope. Please note that this has
no effect when the Hold parameter is at Null! So to make
the particular modulation have an effect a minimum Hold
time must already exist in the Envelope.
Env Decay The Decay Time of the Envelope.
Env Sustain The Sustain Level of the Envelope.
Env Release The Release Time of the Envelope.
Glide Time The Time Glide takes to move to the notes final pitch.
This only works if Glide is active (see the Glide section of
this manual for more details). Like with envelopes, the
modulation takes place once at note start (no continuous
modulation).
Matrix Depth Amount of a specific modulation in the Mod Matrix, often
used with the ModWheel as source to control a specific
modulation parameter.
For Vibrato one would have for example line 1 of the
Matrix read
LFO 0:00 Main Pitch
and another Line would be
Modulation Wheel 2:00 Matrix Depth 1
for a 2 semitones Mod-Wheel controlled Vibrato.
Arp Gate This changes the Gate time (Note Length) of each step in
the Arpeggiator. The modulation covers the full range
from a close-to-zero time where the step starts and the
stops the note right after starting it to the note length
covering the full length of the step.
