Hi Angus,
I wouldn't put it past Rax to cock up some of the MIDI message
handling. I've just taken a look and this is the loop for passing
messages to the music device:
for ( j = 0; j < list->numPackets; ++j) {
Byte* msg = inPacket->data;
do {
if ((msg[0] & 0xF) == m_channel) {
MusicDeviceMIDIEvent(unit, msg[0],
msg[1], msg[2], 0);
if (msg[0] >> 4 == 0x09 && msg[2] > 0) noteOn = TRUE;
}
} while(msg = NextMIDIEvent(inPacket, msg));
inPacket = MIDIPacketNext(inPacket);
}
This is probably very wrong but this code is called in the MIDIReadProc
thread.
Robert.

Hi all,
Am seeing a problem in these AU hosts relating to my MIDI handling
routines.
In Rax and Synthtest, we are seeing frequent, easily-reproducible stuck
notes when played from a MIDI keyboard. The MIDI data handling
routines in
my code look to be OK, so I'm wondering if it might be threading
related.
Are there any special precautions I need to take in the MIDI routines
for a
MusicDevice?
Regards,
Angus.
