Mono and Poly Modulation Sources/Destinations
There are two types of mod sources and destinations: mono and poly.
In general, you don’t need to think too much about which to use when
assigning modulation, but it’s useful to understand the difference.
• A mono modulation source, such as LFO 1: Global, is a single modula-
tor that is applied to all voices in a program equally — with no varia-
tion from voice to voice. Other mono mod sources include the Pitch
Bend wheel or Mod wheel, which can be used to control oscillator
frequency (pitch) or other aspects of a sound depending on how you
assign it in the Mod Matrix (in the display).
• A poly modulation source, such as Key Velocity, is a modulator that
is applied to each voice individually, and can vary in its amount from
voice to voice. A simple example of this is using key velocity to control
lter cutoff frequency per voice or the volume of individual voices
(Amp). Other poly mod sources include LFO 2, Envelope 1, Envelope
2, Note Number, and others. These can all be used to control things
such as the pitch of individual oscillators/voices, oscillator wave shape
per voice, and many other things.
• A mono source applied to a poly destination will act monophonically, and
vice versa.
Modulation Examples
Here are several modulation scenarios that illustrate how to use the modula-
tion matrix. The examples provide step-by-step instructions for clarity. Some
of these setups are built into the basic program, which you can recall from
the global menu.
To use the Mod wheel to add vibrato:
1. In the lfo section, set LFO 1 to triangle and set frequency to a
medium value. Set destination to osc all d e t u n e . Set amount to 0.
(You will control the amount with the Mod wheel.)
2. In the modulation section, press the source button. Use the select knob
to scroll to Mod Slot 1 if it’s not already displayed.
3. Use the value knob to scroll through the various mod sources and
choose mod wheel (As a shortcut for steps 2 and 3, you can hold down
the src assign button and move the Mod wheel.)
