Trigger

A trigger is a signal that activates events. Trigger signals

are very diverse. For instance, a MIDI note or an audio

signal can be used as a trigger. The events a trigger can

initiate are also very diverse. A common application for a

trigger is its use to start an envelope.

VCA

VCA is the acronym for Voltage Controlled Amplifier. A

VCA is a component that influences the volume level of a

sound via a control voltage. This is often generated by an

envelope or an LFO.

VCF

VCF is the acronym for voltage-controlled filter. It is a

filter component that allows you to manipulate the filter

parameters via control voltages.

Volume

The term describes a sound's output level

Wave

Here: A Wave is a digitally memorized reproduction of

one single wave pass. Insofar it is identical with a Sample

that is looped after one single wave pass. In contrast to

the samples in a sampler, all Waves in the Waldorf Wave-

table Synthesizers have the same lengths and are played

back in the same pitch.

Wavetable

The sound creation in the PPG Red 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

Wavetable will probably sound smooth and pleasant. If

they have a completely different structure, this will result

in wild spectral changes.
