I think we have a fundamental "impedance mismatch" here. What you

think is running status is not what I think is running status.


Your version of running status seems to create more bytes in the midi

stream, where the concept I'm talking about creates fewer bytes. Can

you give me byte values that are sent that would explain what you are

talking about, or point to some documentation?


What I believe is running status I find described in an old document

called usenet midi primer:


http://www.harmony-central.com/MIDI/Doc/primer.txt


Search for running status, the second occurance you find this:


For all of these messages, a convention called the "running status

byte" may be used. If the transmitter wishes to send another message

of the same type on the same channel, thus the same status byte, the

status byte need not be resent.


That's what I'm talking about. It means that the two hex byte

sequences "90 45 40 90 47 42" and "90 45 40 47 42" mean the same thing

(two note on messages); the second string can leave out the second

"90" note-on status byte because it is implied by what's called the

running status byte convention.
