Reset
mono
The LFO is shared between the voices of a Program. It may be
at any point in its cycle when the first key is pressed. New voices
will "ride" that LFO, joining other voices at the exact same point
in the LFO's cycle. The LFOs in each Program are independent
of each other, so they can be running at different speeds.
poly
Each voice's LFO is completely independent of the others. When
a key is pressed, that voice's LFO may be at the top of its cycle,
at the bottom, or anywhere else in the cycle when it begins to
affect the voice.
key-mono
The LFO is shared between the voices of a Program. When the
first key is pressed, the LFO's cycle resets to the beginning.
When a second key is pressed, the LFO will reset its cycle to the
beginning and start over.
key-poly
Each voice has its own LFO that resets when the voice is
triggered.
tempo lock
The LFO resets when the master tempo clock hits the "1," as
long as TempoSync is set to "follow tempo".
MOD1 wheel
To place the LFO's amplitude under the total control of the
(MOD1)
wheel, set this value to 100%. To
ignore the
(MOD1)
wheel altogether, set the value to 0%. Values in between allow for limited
(MOD1)
control over the LFO.
13. Sample-and-Hold (S&H) settings
The first three settings –
TempoSync
,
Rate
, and
Reset
– operate
identically to the LFO settings listed above. Here are the additional
S&H settings:
Input
The Input to the Sample & Hold determines the source of the
S&H values. If the source is continuously active, like an LFO,
there will be an endless supply of new values for the Sample &
Hold to feed to its destination in the mod matrix. If the source is
something more static like one of the wheels or pedals, the
destination will receive new values from the Sample & Hold only
after the value of the input is changed and another sample is
taken.
The inputs for the S&H generator are the same as the
Modulation Matrix's modulation sources (discussed later).
Smoothing
This parameter governs the abruptness of the shift from the
value of one sample to the value of the next. A low smoothing
value causes the sample values to change instantly from one
value to the next when the new sample is taken. A high
smoothing value causes the Sample & Hold to "slide" from one
value to the next.
Remember that it is possible to
have the LFOs set independently,
so that one LFO's Reset
parameter may be set to
poly
, for
example, while the other's is set
to
key-mono
.
Synchronizing the LFO's to
your Sequences and Rhythms
If you want your LFOs to sync up
with your Sequences and
Rhythms, set TempoSync to
"follow tempo", and set Reset to
"tempo lock".
Why is my LFO not working?
If you routed an LFO to a
destination in the mod matrix, but
it doesn't seem to have any effect,
check the "MOD1wheel"
parameter. If this parameter is set
to 100%, then the LFO will only
be active if the
(MOD1)
wheel is
up. If you want the LFO to always
be active, set this parameter to
0%.
What does Sample & Hold
mean?:
Sample & Hold is a term
that originated in the early days of
analog modular synthesizers. It
describes the process by which a
reading, or "Sample," is taken at
regular intervals of a particular
input source, such as an LFO.
That Sample becomes a value
that is fed to a destination, such
as filter frequency. The
destination parameter is held at
this value until the "Hold" period
has expired, at which time
another Sample of the input
source is taken and fed to the
destination, and so on.
S&H Smoothing:
With Sample &
Hold smoothing set to very high
values, it is possible that very little
or no change may be heard at the
destination. If you're not hearing
the desired amount of S&H, try
decreasing the smoothing value.
