[linux-audio-dev] LADSPA math plugins?

[Dave Robillard]

Are there any simple math plugins for LADSPA?  Like, scaling of a
signal, sum of signals, dif of signals, etc. etc.

As an example, I'd like to take the output of an envelope in the range
0-1 and scale it by about 300 to make it appropriate for modifying
cutoff value.  Fiddling with signals mathematically is fun anyway.

I'm sure I could hack one out pretty easily, but if they already
exist...
