There are three modifiers to the Amount of modulation: the Amount control, the
Shaping CV, and the Mod Wheel or MOD1 input level. The Amount level is the final
level control which sets how much both the Mod Wheel/ MOD1 Input and the
shaping CV allow the mod source through to the mod destination.
To try out a simple modulation, set the LFO to about 6 Hz, the Source to triangle
wave, the destination to Pitch, the shaping to on, and the amount to 5. The Mod
Wheel can be used to fade in the modulation, which should sound something like
vibrato.
This is a simple use of a mod bus. The flexibility of the two Modulation Busses offer a
wealth of modulation possibilities which make the Voyager an incredible sound
design tool.
SOURCE:
Choosing a modulation source is done through a combination of the Mod Source
Switch and the menus of the software. The Mod Source selector switch is a
6-position switch. The Front panel selections are:
-
TRI
: LFO Triangle Wave
-
SQ
: LFO Square Wave
-
S+H
: Sample and Hold output
-
OSC. 3
: Oscillator 3
-
ON/MOD2
: with nothing plugged into the MOD2 jack, this is a 5 V signal.
The MOD2 input is for using external CVs as a Modulation source.
-
NOISE/PGM
: This is a programmable source for the mod bus with Noise as the
default.
The programmable Mod source is set in the EDIT mode menu
items MOD WHEEL PGM SOURCE or PEDAL PGM SOURCE.
SHAPING
:
The shaping is a way to dynamically change the amount that the Mod Source
modulates the Mod Destination. Shaping occurs before the Amount control and
before the Performance controls. The switch that selects this is a 4-position switch
that is labeled:
- FILT. ENV.:
This allows the filter envelope to shape the amount of Modulation
before the Mod Wheel or MOD1 performance control.
- VELOCITY
: This allows Keyboard Velocity to shape the amount of Modulation
before the Mod Wheel or MOD1 performance control.
- PRESSURE
: This allows Keyboard afterpressure to shape the amount of Modulation
before the Mod Wheel or MOD1 performance control. The pressure signal that
comes out of the keyboard is either on or off, thus pressure can be used as a switch
that gives a boost to the amount of modulation.
-
ON/PGM
: This is a programmable shaping for the mod bus with ON as the default.
The programmable Mod shaping is not implemented in Version 1.0 of the
Software. The default, On, is active.
DESTINATION
:
A modulation destination is chosen in the same manner as the Mod source: a
combination of the 6 position destination switch and the software menus. The
Destination switch is labeled:
-
PITCH
: The Pitch of all three Oscillators
-
OSC.2
: The Pitch of Oscillator 2
