Colin Fraser's P3 sequencer needs a 100 ms pause between SYSEX
blocks. To send SYSEX to a P3 from a Linux machine, download
p3sysexcat.c, compile :

  make p3sysexcat

and run :

  ./p3sysexcat foo.syx >/dev/midi

p3sysexcat copies its arguments (or stdin) to stdout, inserting
a 150 ms pause after every EOX.
