Same as on the original PPG, the LFO waveform Square jumps between “no mo-
dulation” and “full positive modulation”. The other three waveforms oscillate
between “full negative modulation” and “full positive modulation”. You can
clearly notice this effect, if you activate MOD>FILTER and switch back and forth
between the various waveforms.
RATE
0...63
The Rate dial controls the LFOs speed. If this is set to its minimum value, the LFO ope-
rates with 0.09 Hz (one cycle in 10,6 seconds). If Rate is set to its maximum value, the
LFO speed reaches 24 Hz (i.e. 24 cycles per second).
Envelopes
An Envelope creates a time-wise variable control signal. It is
for instance used to modulate the filter settings of a sound
within a given period of time. The classic Envelope form
consist of four separately controllable phases: Attack,
Decay, Sustain and Release, which is why it is also called ADSR Envelope. If you press
a key, the Envelope is started. Within the period of time that you have defined with the
ATTACK parameter, it first rises to its maximum value. Then it needs the time set with
the DECAY dial to fall to the value set with the SUSTAIN dial. It remains there until
you let go of the key. Then the Envelope sinks back to zero within the period of time
that you have set with the RELEASE dial.
The PPG Wave 2.V has two ADSR and one AD Envelope with positive or negative de-
flection, which can also be edited graphically. Find additional information in the secti-
on “Graphical Editor (Graph)” on page 28 of this manual. The illustration below
