Emu XL-7 & MP-7 User's Group

Whoa, that did get released?  Wow.  For the E4's tamer filters, it wasn't really a problem.  On the P2k/XL-7 side, the 12th order filters were a little, um, excitable.  =)  I do seem to remember there being two cord destinations, one for RT Q and the old one for note on Q.  Hmm, maybe we proto'd that in the XL-7 too?  It's been a while...

Oops, I mean 4.71 . I installed it on E6400 Ultra, and haven't 
noticed any glitches - should I have?
