var - Variable, copies its input value to its output value.
Inputs:
value [BUFFER|FLOAT|STRING] [REQUIRED]: value of the variable (string or float).
min [FLOAT] [OPTIONAL]: min value (if value is a float).
max [FLOAT] [OPTIONAL]: max value (if value is a float).
Outputs:
value [FLOAT|STRING]: output value equal to input value.
Simply passes through its input value to its output value.
When input value is a float, min and max can be used to clamp the input value.
var is particularly useful when the input of a module is to be propagated to multiple nodes, or simply when the same value needs to be used and tweaked in multiple nodes in the same SNDC file (e.g a BPM).
