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

hello everybody
I'm a producer from Amsterdam, and all in all quite happy with the XL7 in my
(live) set up, there are a couple of things I don't understand:
- is there a way to delete a complete pattern (like the presets that come
with the XL-7, which I find kind of embarassing)?
It seems like a kinda complex workaround to have to delete all the seperate
tracks, or delete all of them together (but then you still keep the original
name. 

second question:
in the studio I use the XL7 also as a soundmodule with Logic. I've installed
2 more boards (MP 7 and Techno synth) but I can't seem to find a way for
Logic to play the Phatt and Techno (it only recognises the first 4 banks,
which are from the XL7)

cheers
