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

Hey gang,

I want to hook up the XL-7 to my Boss SP-505 (sampler). I want the XL-7's 
sequencer to control the pads (samples) on the SP-505. For instance, when a 
note is programmed into a pattern on track #1 of the XL-7, I want it to trigger 
pad #1 on the SP-505. According to the 505's manual, I need to send a "MIDI 
Program Change Message" from the XL-7 to the 505. I need to use PC #17 
and upwards to access the card (user) banks in the 505. How do I send these 
messages from the XL-7? I found in the manual how to receive Program 
Change Messages in the XL-7, but not how to send them. 

Also, I don't want the patterns on the SP-505 to start playing - I just want to 
trigger the pads themselves. Right now, all I can do is start the patterns of the 
SP-505 using the XL-7. In order to trigger pad #1 on the 505, would I have to 
program a certain note into the sequencer of the XL-7 (ie: C#2)? 

Thank you very much to anyone who's able to help,
Fab
