========================

not sure when i'll have a chance to test it, but based on page 5 of the 
sysex book (the "count" parameter) that seems more likely to work in an 
abbreviated form since it's multiple commands of the same type (the "01" 
in the first line)...

  F0 18 0F dd 55 01 cc
 	07 21 xx yy
 	79 20 01 00
 	04 21 xx yy
 	79 20 00 00
      ck
  F7

where "cc" is the number of bytes to expect and "ck" is the checksum. i 
think the correct byte count in that example would be 0x0F (and i think 
the byte count in the long form, top, should be 0x04 instead of 0x02). 
i'll report back when i find out...
