Hold Until Decay
When on, this parameter causes all notes in the layer to sustain through all three attack
segments in their amplitude envelopes even if the notes have been released. Looped
amplitude envelopes will not loop, however, if the notes are released before reaching the end
of the final attack segment. Notes will go into their normal releases if they are released after
the envelope has looped. When set to Off, notes will release as soon as a Note Off message is
generated.
The Wiring Algorithm (ALG) Page
Press the ALG soft button to call up the Wiring 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 Channel/Zone buttons.
The basic definition: 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
Forte’s algorithms are the core of Variable Architecture Synthesis Technology. The DSP
functions are synthesis tools (filters, 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 and a graphic representation of the signal path, as well as the
currently selected DSP functions within the signal path.
To use a different algorithm, select the Algorithm parameter and use any data entry method
to select a different 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.
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.
