Interesting question. My guess is that the minimum time is determined by
MIDI transmission rate. I.e., how fast can you send a record start/stop
EDP via MIDI. If so, I think it is about 3.84 millisecs. My calculations
MIDI transmit rate = 31.25 Kb/sec = 31250 bits/sec
Note On message = 3 bytes (1 status + 2 data bytes)
Note Off message= 3 bytes
EDP record start/stop = Note On + Note Off + Note On + Note Off = 12 bytes
MIDI transmits each byte as 10 bits.
therefore, EDP record start/stop = 120 bits.
EDP record start/stop Transmit time = ( 120 bits / (31250 bits/sec)) = 3.84
Of course, Kim might tell us that the EDP stops recording as soon as it
second Note On message, in which case the minimum would be:
( 90 bits / (31250 bits/sec)) = 2.88 milliseconds.
I'm assuming the EDP can recognize and act upon the Note On message
But I was never good at arithmetic...
