e central portion of the page shows the algorithm for the currently selected layer. You see
the number of the algorithm and a graphic representation of the signal path, as well as the
currently selected DSP functions within the signal path.
To use a dierent algorithm, select the Algorithm parameter and use any data entry method
to select a dierent one. To change the DSP function within an algorithm, move the cursor
to the block you want to change, then use the Alpha Wheel or Previous/Next buttons.
ere’s a staggering number of combinations of algorithms and DSP functions alone, not to
mention the numerous controls that can be used to modify the DSP functions.
See Algorithm Basics below for information on editing algorithms.
Algorithm Basics
Each of the factory algorithms represents a preset signal path. (See the Dynamic VAST
section below for details on making user algorithms with custom signal paths.) Take a look at
Algorithm 1 in the diagram below. It’s one of the simplest algorithms.
e DSP functions are represented by the rectangular blocks. e lines connecting the blocks
together indicate the ow of the digital signal from left to right; they represent the “wiring”
of the algorithm: the path that the signal follows through the algorithm. Selecting dierent
algorithms can be compared to connecting dierent DSP functions with dierent wiring
diagrams.
ink of the left side of each block as its input, and the right side as its output. 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. If the last block has two wires at its output, we call it
a double-output algorithm. If it has one wire, it’s a single-output algorithm, even if there are
two wires in earlier portions of the algorithm.
Note: Changing a layer’s algorithm can aect the layer’s sound drastically. It’s a good idea to bring
down the volume of your Forte SE or your sound system before changing algorithms.
