Ubuntu :: Start Program (that Lacks --display Flag) On Second Monitor?

I was thinking to do my music producing completely on linux and found a plethora of good tools for it. The thing is I have two monitors and instead of launching manually every little app each time I feel creative, I want to make a script that launches all my favorite apps.

So long I have written this little bash script:

Code:

#!/bin/bash
#Start my audio programs for music production
(qjackctl --start)&
(hydrogen --nosplash)&
sleep 1
ardour2

So what it does is that it starts the jack server, then hydrogen and lastly ardour2. The thing is that I want hydrogen to start in the second monitor but don't know how. I have devilspie but I didn't have any luck on finding some command to choose display. I am aware of the --display flag that some programs have like firefox but hydrogen doesn't have it. Btw I use a different X server on each screen. is there a universal way to launch ANY kind of program on a specific display?
