General Discussion
CVs 33-42 allow the user to customize which DSD outputs or sound effects are controlled by which
function keys. Each function input, FL through F8, is assigned a unique CV that allows the corresponding
function control to be redirected to up to eight different DSD function outputs or sound effects. This
allows a single function key to control more than one output if desired.
This feature is especially useful when the DSD is used with a controller that has less than eight function
keys as the user can select which DSD outputs and sounds are important and re-map them to the
available function keys. Some outputs or sounds can be sensibly tied to another output thus freeing up a
function. For example, the dynamo sound could be configured to turn on whenever the headlight or
backup light was on.
It is also possible to control a given output with more than one function key. In this case, the output will be
turned on when any of the corresponding function inputs are active. The output will turn off only when all
relevant inputs have also been turned off.
The FL function has two CVs - one for forward direction and one for reverse. Function outputs mapped to
these registers will be directional unless the same output is mapped to both CVs.
Note that all function inputs cannot be mapped to all outputs. The matrix below graphically indicates
which inputs can control which outputs:
