Hi there.  Any of you technically oriented net people into MIDI?
What I'm specifically interested in is making the ST perform a MIDI
Thru function.  I half-remember seeing in some magazine that the ST designers
decided to incorporate the MIDI Thru function into the MIDI Out jack.
I have a sequencing program called Master Tracks Pro that has a MIDI
Thru icon.  You click it and *poof* - instant Thru jack.  It seems to
run all the time - even if the computer is tied up doing disk i/o or
menu handling or what have you, the MIDI data keeps on flowing in real
time.  This leads me to believe that maybe there's some sort of system
call or something I could do that would get MIDI flowing.  Is this so?
I'd like to write a desk accessory that would just ask for input and
output channels and instantly turn the ST into a THRU box as I like to
diddle with my synths while using other programs, like Uniterm.  So, is
this a simple sys call or a complex interrupt driven task?  I could
write a dumb loop that just did Bconins and Bconouts to the midi ports
but that would take over the machine completely.  Help please!  Reply
directly to the address below.  I'll summarize responses.  Thanks!
