Andrew I have the same issue with my Roland Sonic Cell. The pat file that's posted does not include the "Rhythm" bank. That's the bank with all the other drum kits. I have access to all of the SC instrument patches but I'm stuck with just the GM drum kits. I have a new Athlon Phenom Win 7 64 bit PC and decided to really get into my Sonic Cell before I install all my softsynths and I've been going crazy trying to figure out where's the drum kits. I finally opened the file in Notepad and they're not there. I spoke to Rob at Support yesterday and he was trying to email you and also to open the file on his computer but kept getting syntax errors. His suggestion for me was to do the same thing, manually add the Rhythm bank to the end of the existing pat file because Real Band doesn't use a separate dk file. On the SC Yahoo groups forum there is a separate Rhythm bank .ins file. I'm wondering if I download that would RB convert it to a pat file, then I take that file and just append it to the other pat file? What do you think is the best way to do this?
Will those drum kit patches then show up just like all the other patches and I can pick one for the drum track because I always thought midi drum kits were somehow handled differently from regular instrument patches. The fact that the Rhythm bank .ins is a separate file seems to support this idea. How are the non GM drum kits accessed on the Ketron?
