The Algorithm (ALG) Page
Press the ALG soft button to call up the Algorithm (ALG) page. The top line of the display gives
you the usual mode reminder, and tells you which layer you’re looking at, as well as how many
layers are in the current program. You can view the ALG pages of any other layers in the program
by using the Chan/Layer buttons.
The basic denition: an algorithm is the “wiring” (signal path) of a sample to the audio outputs,
through a series of digital signal processing (DSP) functions that you select. The PC3A’s
algorithms are the core of Variable Architecture Synthesis Technology. The DSP functions are
synthesis tools (lters, oscillators, etc.) that you assign to the various stages of the algorithm. The
DSP functions you choose determine the type of synthesis you use.
The central portion of the page shows the algorithm for the currently selected layer. You see the
number of the algorithm (from 1 to 28, 101 to 131, and the IDs for any user-dened algorithms)
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 Plus/Minus buttons. There’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.
