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. This feature is known as cascade mode, because the output
of each layer can cascade into the input of another layer. This allows a single layer to be
processed by up to 32 layers of algorithms.

DSP Functions

Several DSP functions are available including filters, equalizers, oscillators, amplifiers, 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).
The 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
Control (DSP CTL) Page" on page 3-53
page 3-55.

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. The right-most AMP block always controls the final 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. The
smallest DSP function is a single DSP block, it can have a single adjustable parameter, and
4 of these DSP blocks can be fit in a single layer. The 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 fit in a
single layer.
To select a DSP function, use the navigation buttons to select a block, then use the Alpha
Wheel or PREVIOUS and NEXT buttons to select one of the DSP functions available for
the selected block. Based on the selected block's size and wiring, different DSP functions will
be available.
