Re: [ecasound] Ecasound LADSPA parameters floating-point parameters rounded to integer.

Hi,

Thank for your answer.

Yes it Works Well.

I found an other way to quick fix this issue by writing parameters in
"scientific mode" (E notation) so
0.315 is written 315E-3

Thank's a lot for good you work.
