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

The artist formerly known as rEalm referenced an unreleased Command 
Station OS that had the realtime filter controls (resonance).

The smiley face made me think perhaps he had a copy of the beta 
version.

Anyone here have a copy of that beta version?

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...
