What do you mean by "very slow rate"? MIDI has fixed speed, and SysEx  
data must use the same speed as other MIDI data.

The only problem connected with speed, when we send data for example  
from MIDI sequencer and can set fast or slow tempo, can be when  
there's more blocks in data file (each of them with it's own SysEx  
header) and these blocks are sent without pause between them... Then  
some more sensitive instruments with small MIDI input buffer or not so  
powerful CPU can have trouble.

Are you sure data file you want to send is OK, and MIDI channel  
encoded in SysEx header (= Device Number) is set also on the  
instrument as receiving channel for SysEx?
