PRO DSP1000P automation with Hydrogen PART 2

The original post can be found here, but to recap :

The goal : control a hardware FX unit with Hydrogen
Why : to be able to select a specific FX per song (or part of the song)
How : using Midi + minimal tools

After some googling and great help from the Linux Audio Developer mailing list (thanks Harry, Jeremy, Clemens, Frank, Olivier, Adrian) my FX unit now switches to a specific preset whenever i jump to the next/previous song in Hydrogen !

PRO DSP1000P automation with Hydrogen ?

Up until now we have always rehearsed and gigged without any FX applied to the vocals.  In fact we use almost no FX on any of our instruments either.  I guess that mainly has to do with the no-nonsense in-your-face type of pop/rock we play.
However, after or last gig my niece said we should add a bit more reverb to the vocals.
When i told her that we have no FX unit (not even built into the mixer) she looked at me as if i was some sort of alien  ;-)

I dont like people looking at me as if i'm an alien, so today we bought a second hand FX unit
