r#"Signal Range Mapper
This node allows to map an input signal range to a precise output signal range.
It's mostly useful to map control signals to modulate inputs.
See also the 'SMap' node, which is a simplified version of this node.

pub const HELP : &'static str =
r#"Map - Signal Range Mapper
This node allows to map an input signal range to a precise output signal
range. It's main use is for precise control of an input of another node.
It processes the input signal as follows. First the input is attenuverted
using the 'atv' paramter and then the 'offs' offset parameter is added:
inp * atv + offs
The resulting signal is then processed by the mapping, that maps
the input signal range 'imin'/'imax' to the ouput signal range 'min/'max'.
The 'clip' mode allows you to limit the output exactly to the 'min'/'max'
range. If this is off, the output may be outside the output signal
range if the input signal is outside the input signal range.
This can also be used to invert the signal.
For a more simplified version of this node see also 'SMap'.
