Glossary
Most of the “definitions” below only apply to synthesizer tech-
nology or even specifically to the Virus.
A
„
Adaptive Control Smoothing (ACS)
Smooth but rapid interpolation of parameter changes to elimi-
nate zipper noise.
„
Additive synthesis
Method of creating sounds by summing simple waveforms
(usually sine waves). Complex sounds therefore require many
oscillators. See also
Subtractive synthesis .
„
Aftertouch
Obsolete term for either Channel Pressure or Key Pressure .
„
Allpass filter
Type of filter which does not remove frequencies from the sig-
nal, but only affects its phase .
„
Amount
How much a modulation source affects its destination.
„
Amplitude
A non-scientific definition would be: loudness, level, volume
etc..
„
Arpeggiator, Arpeggio, Arp
In classical music, Arpeggio means you should play the notes
of a chord in rapid succession instead of all at once. In the syn-
thesizer world, Arpeggiators are clocked processors that turn
chords into (usually) repeating sequences.
„
Attenuation
Reduction of amplitude etc.. Usually measured in dB . Opposite
of Gain .
B
„
Balance
Simultaneous control over the relative levels of two signals.
See also
cross-fade .
„
Bandpass filter (BP)
