It is to me! My understanding is that you can utilize MIDI to do many things other than have keyboards and sound modules communicate. You can have stage lighting or fx changed at a particular time in a song or program... or a spot speaker turn on or off, just to name a few... via MIDI and sysex. Usually the sysex info is embedded in the SMF, in the form of something like this:

F0 26 7B 33 00 0E 01 F7

Does anybody know what this means? Does the first 2 digits mean this and the next 2 digets mean that??
