I probably left something that could be read that way.  I didn't go into 
detail on the JUNO's and I'll try to fix it if it's in the section I 
wrote...  otherwise I'll leave it for Tom.  But the main difference in 
60 and 106 I think is analog envelopes on the early junos and probably 
just a little different set up on the filters though they really are 
using the same parts inside those modules. -Bob
