Hi Jane,
I tried to reproduce your error and couldn't. Here's what I did:
1) create a file with the sysex message:
F0 7E 4C 6 2 18 4 4 5 0 32 2E 32 36 F7
2) run pm_test/mm to monitor input
3) run pm_test/sysex
Use send (s) to send the file
4) look at the data printed by pm_test/mm:
F07E4C06 System Exclusive
02180404 System Exclusive
0500322E System Exclusive
3236F7 System Exclusive
I tried over the IAC Driver Bus and through a loop out and back into a
USB MIDISport 2x2, and also sending with 0 latency and non-zero latency.
It is still possible that some other driver is forming packets in a
different way and PortMidi is not interpreting them correctly. Can you
try this loop-back test on your hardware? You could also run pm_test/mm
to receive the Proteus sysex message to make sure that at least 2
programs (yours and pm_test/mm) agree on what data is actually delivered
by PortMidi. I'm running OS 10.4.11 on a MacBook Pro.
I don't know about the 'Service name already exists' message. If anyone
has looked more at the Core Midi internals and has any ideas, please let
us know.
Thanks,
Roger
