[LAU] controlling LADSPA plugins whith a midi pedal ?

[Benoit Rouits]

hello,
Being fed up with controlling LADSPA plugins with the mouse
(i have only 2 arms on the piano already..) I wondered if
i could buy at least one midi pedal an control one of the parameter
of a ladspa plugin (inserted in jack-rack or OM f.i.) with it.

I heard OM is controllable with OSC but i know nothing of it.

have one of you any experience/links ont that topic ?
- thanks in advance.
