FEATURES AND FUNCTIONS El
The trigger signal you use to trigger GEG
operation can come from the keyboard
(KBD TRIG) or similar source, in which
case it is a voltage trigger signal; or it can
come from a switch such as the momentai
switch
(M*SW)
or
a
foot
switch,
in
whicl
case the trigger signal is like a switch in
that it just triggers the beginning of operat-
ton.
Figure 26 is an attempt to convey the
different relationships between the two
types of trigger signal and the envelope
produced. Figure 26 also shows how the
envelope will change depending on which
output jack you use.
Note that when the GEG output voltage is
OV, the section you are controlling will
operate at the level of its knob settings. (In
other words it will operate “normally” as if
there were no outside input.)
So, when you use the GEG, think carefully
about the type of effect you want; then
choose your trigger signal and output jack
accordingly.
