I think this is beacuse of the way drum kits are constructed in the 
emu architecture. I havent looked into the xl-7 that much, but on the 
Vintage Keys the drum kits are not really mapped instruments. It's 
been a while, but I remember drum kits actually being one long sample 
where each of the individual drum sounds were accessed by changing 
the "sample start time" paramater. The value of sample start time 
would change linearly with the note number. This way you get a drum 
kit with only one layer. To make your own kits you had to build a 
layer for some stretch of notes you want, then another layer for some 
other stretch of notes and so one linking patches until you have 
enough layers to satisfy yourself. This eats polyphony like mad since 
it counts each layer as a voice whether it plays for that note or 
not. This is not as big a deal on the 128 voice xl-7, but on the 32 
voice vintage keys it was a big problem.
