Triple Modular Processing
Overview
Note that any processing in Layer 2 that’s “downstream” (to the right) of the input(s) from
Layer 1 gets applied to the signals from both Layer 1 and Layer 2. After the processing in
Layer 2, the signal passes to Layer 3 for still more processing before going to KDFX.
Any non-KB3 program can contain a triple, alone or in combination with normal layers and/or
other triples (KB3 programs don’t use layers, so they can’t contain triples). Each triple is a
contiguous set of three otherwise normal layers, with all the usual layer parameters. Because
their audio paths are linked, the layers of a triple are always numbered consecutively. You can’t
reorder the layers within a triple, but you can locate the triple anywhere within a program. For
example, a ten-layer program might contain two triples: one triple spanning Layers 2–4 and the
other spanning Layers 7–9 (with Layers 1, 5, 6, and 10 being normal layers).
Triples and Polyphony
Each triple uses three voices, the equivalent of three normal layers. By using a triple instead of
three normal layers, you add millions of sound-editing possibilities without using any more
voices. If you play enough notes to exceed the K2661’s polyphonic limit, the three voices used by
each triple get stolen as a unit, according to the priority set by the parameters on the AMPENV
page of Layer 3 of the triple.
Soloing and Muting
You can solo and mute triples much as you can normal layers. Soloing and muting always
affects the entire triple, however; you can’t solo or mute individual layers of a triple.
KB3 Programs
You can’t use triples in KB3 programs, since KB3 programs don’t use the VAST model. That is,
they don’t consist of layers like non-KB3 programs (instead, every KB3 program plays notes that
are generated by tone wheels that start running as soon as you select the program).
Consequently, KB3 programs can’t contain triples, because triples are specialized layers.
Even so, KB3 programs can coexist in setups with programs that use triples. Keep in mind
though, that since a typical KB3 program uses about 40 voices, any setup that uses one of these
programs has only eight voices left over. This means that you might not always hear every note
of a setup that contains both a KB3 program and one or more programs containing a triple (or
multiple triples). Whenever a KB3 note is playing, the K2661 can play a maximum of two notes
from triples.
Note : You can edit a KB3 program to reduce the number of tone wheels it uses, which frees up additional
voices (one voice for every two tone wheels).
Live Mode
Live Mode enables you to take an external audio signal and route it through the K2661’s VAST
sound engine. (This works only if you have the Sampling Option installed in your K2661.)
Triple-modular processing makes for an even greater number of possibilities in Live mode. For
example, a triple can route a single Live-mode input through three layers of DSP, or it can mix a
Live-mode input with an internally-generated K2661 sound. A triple can also mix two Live-
mode inputs with each other and/or with an internally-generated K2661 sound.
