Don't post too much - but sure do enjoy reading and learning.  Just wanted to thank the many forum members who have said good things about George.  I have never done business with him, but based on the reputation he has on SZ, I reached out regarding the new Roland Arranger module.  George was awesome - after answering my questions, I gave him my credit card number with a smile.  As a small business owner, I appreciate his level of expertise and knowledge. I can't always do it, but it felt good giving him my money instead of a big chain.  Add me to the group of happy customers recommending George.
As for the module, I will be using it with my Motif XS8.  I own a small company that develops and markets content for the web and mobile devices.  My mid-life crisis has taken the form of playing and creating music again.  So I bought the Motif to write my own background tracks for podcasts, websites and videos.  Sometimes I need something quick, or just want to play with backup.  I love my MOTIF (thinking about ordering the XF8), but it is not an arranger.  The BK-7m fills a much needed space - small and priced well.  Looking forward to sharing thoughts and some videos when the unit arrives.
