Positive values increase the release time as you play higher up on the keyboard;
negative values decrease release time as you play higher up on the keyboard,
The effect of Keymod increases drastically at longer delay times, so much so that
notes at the extremes of the keyboard may appear to be stuck on, whereas in reality
they just have an extremely long decay time. Set Keymod to lower values at first (e.g.,
-10 or +10, depending on how you want release time to track the keyboard) and try
tweaking T4, the release time, to arrive at the desired decay curve. Go back and forth
between T4 and the Keymod setting until you achieve the desired sound.
3.10 LFOs (LOW FREQUENCY OSCILLATORS)
The Low Frequency Oscillator (LFO) creates a cyclic (periodic) modulation of syn-
thesizer parameters such as pitch, volume, or filter cutoff. Applying a periodic
modulating signal to the oscillator produces vibrato; this is such an important applica-
tion that the DPM V3 lets you control the LFO signal amplitude with the modulation
wheel or a pedal, so you can add vibrato in real time as you play. The amount of
vibrato (or other LFO-induced modulation) can also be set to a constant amount, or
some combination of the two.
Applying LFO modulation to the VCA produces tremolo; modulating the filter cutoff
with an LFO signal produces a wa-wa effect or, if used subtly in the higher registers, a
shimmering type of sound.
The DPM V3 includes two independent LFOs, with five pages of parameters, as
modulation sources. Since they are identical, we will discuss only one LFO's set of
parameters.
