Midisport and sysex



Dear list!

I'm having trouble with my MIDISport 4x4 and sysex.

I have just found out that if I send a dump request message from my app:

- Kurt Revis MIDI Monitor says that 6 bytes has been sent to port A, and
it's the complete request message.

- MIDISPORT 4x4 is not receiving sysex (no red lamp is blinking) and my
synthesizer is not responding.

This happens only after my app is just started. If I send the same sysex
request again, everything works and willl continue working. Until the next
time I start my app.

I made a change in my app so it now sends out some controller messages
after startup, this seems to solve the problem (not 100% sure). So it seems
that the MIDISport driver is having trouble with some sysex status flag or
something. Can this be a driver problem in the MIDISport 4x4? The driver
version I'm using is 3.1 with latest OS X panther version.

Peter
