This patch adds some improvements in Alsa Modular Synth.
A new LADSPA Browser based on the one in Ardour.
A new Drum MCV based on the Advanced MCV but that reacts only to a specific note, and a Drum Envelope that ignores NoteOff.
And finally a XY module that uses the position of the mouse cursor on the screen to control other modules.
Please post 1 patch per feature.
