reach its full amplitude. This can be used to slowly increase the amount of
modulation applied. A setting of 0 means that modulation commences
immediately. Attack in only active when the LFO not runs in Mono mode

Mod Matrix
The Spectral's Modulation Matrix allows you to create 24 modulation
routings. More than 170 modulation destinations are available for
modulation by more than 30 modulation sources (see Appendix B and C for
a listing and description of all modulation sources and destinations).
Modulation sources are shown in a column on the left of the display, while
the destinations are shown on the right. The modulation amount is
displayed in the middle. To change a routing click on the source or
destination that you want to change. A menu will appear which lets you
select the new source or destination.
To remove a modulation source or destination select the "- - -" entry in the
menu. Each modulation routing can be switched on and off by double
clicking on the modulation depth in the middle.
To change the modulation depth click on the amount display and move the
mouse (while keeping the mouse button pressed) upwards or downwards
(increasing or decreasing the value) until the desired amount has been
reached. A negative modulation depth inverts the waveform of the
modulation source.
