Alt Input
When the Alt Input parameter is set to None, the Keymap of the current layer is used as the
algorithm input signal.
When the Alt Input parameter is set to 1-32, the output of the selected layer number is used
as the algorithm input signal. is feature is known as cascade mode, because the output
of each layer can cascade into the input of another layer. is allows a single layer to be
processed by up to 32 layers of algorithms.
Note: When Alt Input is set to a layer which uses a stereo keymap, or a layer which uses a
wiring algorithm that has separate left and right outputs (Output Mode set to Sep. L/R),
only the left channel of the stereo signal is used by the receiving layer.
DSP Functions
Several DSP functions are available including lters, equalizers, oscillators, ampliers, mixers,
panners, distortions, shapers, and aliasers. DSP functions contain adjustable parameters
which can be set to a single setting, or controlled by a physical controller or other control
source (such as an LFO or envelope).
e DSP functions are represented in the algorithm diagram as rectangular blocks.
Each DSP function has one or more parameters to which you can adjust and apply a variety
of modulation sources on the DSP CTL and DSP MOD pages. For details see “The DSP
Control (DSP CTL) Page” on page 3-58 and “The DSP Modulation (DSP MOD) Page” on
page 3-60.
PITCH and AMP
Each algorithm contains a PITCH block at the input, and AMP block at the output. When
the Alt Input parameter is set to None, the Keymap of the current layer is used as the
algorithm input signal. In this case, the left-most PITCH block controls the pitch of the
samples in the keymap. e right-most AMP block always controls the nal amplitude of the
signal.
Selectable DSP Functions
Between the PITCH and AMP blocks, up to 4 DSP functions can be selected.
DSP functions vary in size depending on their complexity and number of parameters. e
smallest DSP function is a single DSP block, it can have a single adjustable parameter, and
4 of these DSP blocks can be t in a single layer. e largest DSP function is a 4 block DSP
function, it can have up to 4 adjustable parameters, and 1 of these DSP blocks can be t in a
single layer.
