I hear all of you
But the release of version 2.12 is suffering from a huge delay... I'm currently testing an alpha version of v2.12, but it still needs some additional coding so it will definitely take a few other months. It's one of the most complicated version upgrades of EMXP that will ever have been released (although most of this will not be viewable by the users; the complexity sits "under the hood").
Once this version is released, the SP is the next thing that will be added. Adding SP support will be the start of the version 3.xx series of EMXP.
BTW: Unless someone offers me an SP1200 for a reasonable price, the first SP that will be supported will be the SP12. Because that's the one I have here in my studio... and I really need to have all samplers/drummachines in my studio for a pretty long time in order to get them supported by EMXP.
