Step 3: Function Mapping
What is Function Mapping?
Function mapping allows the DSD to be reconfigured to allow sound effects
and function outputs to respond to different function keys. This is especially
useful if your throttle has fewer than 13 function keys, as it allows you to
select which effects are active and which keys will control them instead of
being restricted to default function assignments.
There are 14 total function mapping CVs. CVs 35‑46, are used to assign
control to function keys 1‑12, respectively. CVs 33 and 34 relate to the F0
function. CV 33 controls which outputs are active when F0 is on and the cab
is set in the forward direction. Conversely, CV 34 controls which outputs are
active when F0 is on and the cab is set in the reverse direction. If the same
effect/output is selected for both CV 33 and CV 34, that function will turn on
whenever the F0 function is on, regardless of direction.
Not all function keys can control all outputs or effects (see Table D). Note that
a function key can be set up to control more than one output.
