Rocktron Xpression - Manual (Page 31)

The Tremolo effect continuously varies the volume of the signal.
The PARAMETER SELECT control will allow you to access each of the following
Tremolo parameters:
The PARAMETER ADJUST control allows you to adjust the selected parameter:

TREMOLO I/O
TREM DPTH
TREM RATE
SHAPE
TIME
The TREMOLO I/O parameter determines whether the tremolo circuit
is active or bypassed for the current preset. Select IN if you want to
engage the tremolo. Select OUT if you want to bypass the Tremolo.
The TREMOLO DEPTH parameter determines the amount of modula-
tion for the Tremolo signal. Lower DEPTH settings produce more
subtle tremolo effects, while higher settings will result in a more
extreme tremolo effect.
The TREMOLO RATE parameter determines the speed at which the
tremolo signal modulates (or increases and decreases in volume).
The SHAPE parameter determines the waveshape of the tremolo
signal. Selecting a different waveshape produces a different tremolo
effect.
The TIME parameter determines the multiplier by which a new
modulation rate will be selected for the RATE parameter when the Tap
Delay feature of the Xpression is used. (See Section 7 page 50: "Tap
Delay" for more information on the Tap Delay feature.)
