The slider is expected, as the plugin defines one:

ControlPort =    Gain    |  gain
Range =  0|    2

Now the distortion, I don't know. The max gain
will double the amplitude, so it might distort.

I never used Rosengarden, so I don't know anything
about it. So far I tested csladspa on Linux and
OSX with Audacity and Ardour and it works as expected
on both programs and both systems.
