Hi,  Regarding the recording of MIDI music on a file, Robbie stated,
"the MIDI data file contains time information, actually stored as
measures and beats along with metronome information.  The program that
plays the MIDI file reads the metronome setting and the meter (3/4 or
4/4, etc.) to determine how fast to play the music."

I also would like to understand the recording process because I would
like to use the MIDI technique for a few simple projects that I have
in mind.  I also completely understand the basic MIDI signal and have
made MIDI-to-contact decoders using that understanding.  These decoders
I speak of can read a MIDI signal from a keyboard and a file player
with equal accuracy.

But I don't understand how to make a MIDI file, and when the 'on'
time and 'off' time information is sent.  I also would like to know how
the receiving computer processes these timing events.

Does anyone know where this information is explained in clear detail?

Thanks,
Andy LaTorre
