4.3 FIL. ENV GATE SRC (Filter Envelope Gate Source)
4.4 VOL. ENV GATE SRC (Volume Envelope Gate Source)
These two Envelope Gate functions allow gate sources other than the
keyboard and the external gate input (the ENV GATE jack) to be assigned
to trigger the Voyager XL Envelope Generators when the Envelope Gate
switch is in the ‘ON/EXT’ position. The default parameter for both
Envelope Sources is ‘Envelope Gate Input’ .
The assignable Gate Sources are:
- Envelope Gate Input (this defaults to ON when
nothing plugged into the ENV GATE jack)
- Touch Gate (this is the gate signal from the
TOUCH SURFACE controller)
- S&H Gate (this defaults to the LFO square wave
when nothing plugged into the S&H GATE jack)
- MIDI Clock
- Keyboard Gate
- Gate is ON
- Gate is OFF
4.2 FILTER POLE SEL.
This function allows you to specify the cutoff slopes of Filter A & B. Filter
A is the filter controlled only by the CUTOFF control, while Filter B is
controlled by both the CUTOFF control and the SPACING control. In
Dual Lowpass Mode, the output of Filter A appears on the RIGHT output
jack, and Filter B appears on the LEFT output jack (when both outputs are
connected). In Highpass/Lowpass Mode, Filter A is the Lowpass filter, and
Filter B is the Highpass filter. Use the -1/+1 buttons to select the cutoff
slope, which is specified in ‘poles’ (1, 2, 3 or 4 poles). Each filter pole adds
6dB/octave of attenuation to the filter cutoff, so a 1 pole filter has a 6 dB/
oct cutoff slope (when it’s a lowpass filter you hear it as very bright), while
a 4 pole filter has a 24 dB/oct cutoff slope (when it’s a lowpass filter you
hear it as smooth and dark, yet warm).
Changes made to the Filter A or B Pole Selection menus take effect immedi-
ately (you do not need to press ENTER). This feature allows you to hear the
result of the change without leaving the menu.
