[jitter] Re: float isn't float ?

Sorry but that's incorrect.

http://freeframe.sourceforge.net/spec.html

The subsections beginning with the word Parameter would be of  
particular relevance here.

I quote from ParameterValue():
ParameterValue

(32-bit float value OR 32-bit pointer)
Definition:

ParameterValue:
Float value from 0-1 or pointer to null terminated string. (See remarks)
Remarks:

Apart from text parameters, FreeFrame parameter values are always 32- 
bit floats, and the range of values permitted is STRICTLY 0-1 (0 <=  
ParameterValue <= 1). This allows faster processing and a good range  
of values over a standard range, so the host can run up sliders or  
similar for the plugin. The Use of any values outside this range will  
result in hideous incompatibilities. The ParameterDisplayValue can be  
used to display whatever actual values the plugin likes e.g. 0-255,  
0-767, 1-256 or whatever. The plugin should translate the standard  
0-1 float range into the values it needs for its processing.
For text parameters, this 32-bit value represents a pointer to a null  
terminated string.
