Some DSP functions are available in dierent block sizes, with larger block sizes generally
oering more parameters or higher sound quality. For example, the one block LOPASS
function is a low pass lter with a single parameter, LP Frq, while the two block 2POLE
LOWPASS function is a low pass lter with two parameters, LP Freq and LP Res. Similarly,
the one block SQUARE oscillator has a single parameter, Sqr Pch, while the two block
SQUARE oscillator also has a single parameter, Sqr Pch, but provides higher sound quality
through anti-aliasing.
In order to select a DSP function, you must rst select an algorithm with the appropriate
block size and wiring. Depending on the size and wiring of the selected block, dierent DSP
functions may be available.
A diagram of the selected algorithm is shown in the center of the page, showing the selected
DSP functions and audio signal ow wiring. In the diagram, the audio signal ows through
each DSP block from left to right.
Depending on the algorithm, the signal may split into two wires, enabling part of the signal
to bypass certain portions of the algorithm. Split wires may rejoin within the algorithm, or
they may pass all the way through as split signals.
The Wiring Alg Editor (Dynamic VAST)
e Wiring Alg Editor allows you to access Dynamic VAST by editing the wiring of an
algorithm. With Dynamic VAST, literally thousands of wiring schemes are possible.
To enter the Wiring Alg Editor, select the Algorithm parameter on the Wiring Alg page,
select an algorithm, and press the EDIT button.
In the Wiring Alg Editor, each function block has three editable parameters: number of
inputs, number of outputs, and block size. (e Output Mode parameter applies to the
entire algorithm.)
