tremolo effects, etc.
A
voice LFO
is specific to each voice, and there will actually be a small amount of
detuning/dephasing between them, for a richer sound.
Consider the example of a guitarist playing a guitar through a tremolo pedal, and applying a vibrato
on a particular note. If you want to program something similar, you will use the
voice LFO
for the
vibrato (because it is slightly different and desynchronized for each individual note) ; and you will use
a
part LFO
for the tremolo, since it uniformly affects all the notes. Another example: you have found
the perfect combination of LFOs to create a trancey gated strings sound. The last thing you want is to
have each note of the chord triggered at a slightly different instant due to difference in timings when
the chord is played. You need a
part LFO
for the gating effect. A
voice LFO
is good for richness and
randomness, a
part LFO
is good for sync’ing things up.
As a result, only the
voice LFO
can be controlled in the modulation matrix (because it can be
controlled by velocity, aftertouch, etc. — all kind of things that might be different for each played note)
; and only the
part LFOs
can be synchronized to tempo.
This
part LFO
vs
voice LFO
distinction sounds confusing, and there is actually little documentation
about it. Most classic analog synthesizers do not have one
LFO
circuit per voice, so their behaviour is
accurately simulated by the use of
part LFOs
. Some VAs, like the access Virus, use
voice LFOs
. On
the Waldorf Blofeld, each
LFO
is a
voice LFO
by default and can be turned into a
part LFO
through
the use of the
sync
setting.

lfo/eg
: Selects the
LFO
/ envelope generator to edit. The settings shown on the page are relative to
the selected
LFO
/ EG. If you are wondering if there is such thing as a “filter envelope” and “
envelope”... Yes, by default env2 is mapped to cutoff and env3 to the
VCA
; but this can be changed
in the modulation matrix by patching pranksters.
rate
:
rate. The first values (1/1 to 1/96) are note values relative to the global tempo (or to an
external
MIDI
clock). For example, if set to 1/4, the
will play one cycle every quarter note. The
other values are increasing frequencies, from 0.06 Hz (0) to 100 Hz (127).
wave (waveform)
:
waveform. A list of
waveforms is given below.
