7 Modulation Section

The MG-1 Plus includes a low-frequency oscillator (LFO) that generates sub-audio range
signals intended for modulation purposes.
Wave Shape- Selects the repeating pattern of the LFO. Available waveforms are triangle,
square, and random. Only one waveform is available at any time.
Mod Wheel switch and LED- This is a really handy, but potentially confusing feature, so
don't skim this section. If the switch is in the off position (left), the LFO is always "on." Its
effects will be immediately audible by moving the Tone Sources, Poly, and Filter modulation
amount sliders. Clicking to the on position (right, LED lit) enables control of modulation
depth with an external keyboard controller mod wheel. If the mod wheel is all the way
down, modulation depth is zero. This makes setting up a mod wheel to add vibrato or wah
effects very easy. If it seems like the LFO isn't working, check if the Mod Wheel switch is
engaged.
Auto Contour Trigger- When set to the In position, the Counter Generator repeatedly
triggers at the current Modulation rate. This is particularly useful when used in a DAW and
combined with the Ext Sync switch (more on this below).
Rate and Ext Sync- When the Ext Sync switch is off, the Rate slider sets the modulation rate
from 0.3 to 31 Hz.
Engaging the Ext Sync switch locks the modulation master tempo. When engaged, the Rate
slider snaps to note values ranging from 8 beats up to 1/64th note triplets. Ext Sync mode
locks to the tempo in the top toolbar when using the DCO-106 standalone version, or to the
current project tempo when the plug-in version is used in a DAW.
