domenic,
1) what about possibility to start open source project for developing another "arranger module" for your keyboard? I mean project to develop this specification: http://www.synthzone.com/ubbs/Forum37/HTML/007317.html -- I did post it at this forum several days ago. May be several of this features already implemented by you?

2) How (and when) I can obtain your Mediastation X-76 here in Moscow, Russia?
