Pipe effects
The effect type Pipe replicates the physical qualities of resonating bodies and resembles a
simple waveguide application. Unlike waveguides based on physical modelling, ABSYNTH's
pipe algorithm does not attempt to realistically simulate existing instruments or other natural
resonating bodies. It is helpful to imagine Pipe as a kind of string or pipe.
Let's take the image of a string. A loudspeaker (a contact loudspeaker) is connected to a string,
which begins to vibrate as a result. You can determine the position of this virtual loudspeaker
on the string via the parameter Input Position. Above the string are two pickups, similar to an
E-Guitar. The pickups' positions can be determined through the parameter Output Positions.
Changing those two parameters can be compared with changing two microphones. You can
modulate the string's length and the pickups' position through the LFOs or a MIDI Controller.
This way, various flanging, pitch-shifting and rotary speaker effects can be achieved. These
effects are particularly apparent when the modulation of the pickups are modulated in op-
posite directions.
Consider the following: When one of the Output Positions crosses the Input Position (when
loudspeaker and pickup would directly be facing each other) a muffled side tone can be heard.
By modulating the parameter called Length, which relates to the string's length, the crossing
values for Length and Input can produce a muffled click. However, it is not a problem to cross
the Output Positions. The graphic representation of the effect Pipe shows the current settings
of the parameters for Input Position, Output Position and Length, as well as for the adjacent
modulations. It should help you to prevent undesired crossovers with the Input Position.
