If ENV3>OSC or ENV3>SUB in the TUNE menu are active, Envelope 3 modulates
the pitch of the corresponding oscillator. ENV 3 ATT either controls a negative
(when turned counter clockwise) or a positive (when turned clockwise) Envelope de-
flection. If SUB-WAVES in the DIGITAL menu is set to ENV3, then Envelope 3 mo-
dulates the sub oscillator waveform. In this case, only the positive deflection form of
ENV 3 ATT can be used.

All three Envelopes can also graphically be edited in the GRAPH-Editor.

This section creates the actual sound. Two
Wavetable oscillators (OSC and SUB) as well as
a 24dB low pass filter with resonance capabili-
ty. Sound creation in the PPG Wave 2.V bases
on waveform sets, called Wavetables. You
should think of these as a sequence of up to 64 single Waves. This can be played
back in a static way or passed through dynamically, which results in the PPG-typical
interesting sound transformations. If the Waves do not differ much, then the Waveta-
ble will probably sound smooth and pleasant. If they have a completely different
structure, this will result in abrupt spectral changes.
The PPG Wave 2.V contains 32 Wavetables and the last four Waves of each Wave-
table are always the classic analog waveforms Triangle, Pulse, Square and Saw
tooth. You should thus first use these four waveforms, if you want to create typical
analog sounds. Additionally, you have the UPPER WAVES, another Wavetable,
which is always available on all MIDI channels. Please also read the section “Upper
Waves” on page 19 of this manual).
CUTOFF 0...63
Similar to the original, the PPG Wave 2.V contains a low pass filter with resonance
capability and a slope rate of 24 dB per octave. This filter attenuates frequencies
above the corner frequency set with the dial. Turning the dial clockwise opens the
filter, so that all frequencies can pass unchanged when the dial is fully up. Turning
the dial counterclockwise closes the filter. When the dial is turned down, you won’t
hear anything, same as on the original PPG.
EMPHASIS 0...63
Emphasis, often also named Resonance, emphasises a narrow frequency band
around the corner frequency. Lower settings between 15 and 50 make the sound
more brilliant and nasal and give it the typical filter character. Please note that hig-
her settings attenuate the level in the same way as the SSM 2044 filter chip did in
the original PPG.

PPG users do especially like the typical sound character that results from high
Cutoff and Emphasis settings. Caused by the combination with the waveforms,
the sound becomes extremely thin and delicate.

quency response:
