Dave just pointed out a minor translation issue :
if you have your system setup in a different language than English, H2 will still load the (English) DefaultSong.h2song > this file also contains some strings that can be translated (eg 'pattern')
Is there a solution for this ?
maybe simply creating multiple DefautSong files (DefaultSong_NL.h2song , _FR, _RU ...) and depending on the system language one of these gets loaded ?

Dave :
"I can confirm the method to change 'Pattern' to in my case : 'Patroon' (of course not the tags themselves ;))
in DefaultSong.h2song."
