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

Hello,

I am trying to send a sysex string to my XL-7 to turn rechannelize on and 
off.  Aaron told me the parameter for this was '420' but I can't seem to get 
the hex right.  Do I "nibbleize"?  This is the string I have so far:

F0h 18h 0Fh 00 55h (420?) 01 F7h

I read in the back of the SysEx Specs and it states:

To find the "nibble-ized" Hex value of parameter number 257:

257 divide by 128 = 2 r1
2 in hex = 02 = msb
1 in hex = 01 = lsb

So when I change "257" to "420"

420 divide by 128 = 3.28125 (don't get it)
3 in hex = 03 = mmb (i'm guessing)
2 in hex = 02 = 1sb (i'm guessing)

I don't think this is correct.  The change message would be "01" for on so 
the string would be:

F0h 18h 0Fh 00 55h 03 02 01 F7h

I can't get it to work.  Any help here would be most appreciated!

Thanks,
Nathan
