BTW, Nedim, thanks for actually getting my point...
Mind you, on a forum of mainly elderly arranger players, I'm pretty sure hardly anyone actually uses a groovebox, and it's pretty obvious few realize what that particular form of playing really needs (or at least what the majority of practitioners of the form actually use) even though a simple scan through the groovebox section in any catalog might show them...
It takes more than silk-screening a word onto a keyboard to actually make it into what is being printed... Just as putting the word "Workstation" onto an arranger doesn't make it into one (at least, not in the contemporary sense of the word), putting the words 'Arranger' or 'Groovebox' onto the MS doesn't magically turn it into one.
