Hi,
When you want to send SysEx messages, you should split
them into small
chunks that are scheduled at proper times so that the MIDI bandwidth
is not exceeded. (aplaymidi does something like this if you give it
a .mid file with huge SysExes.)
However, for this it would be easier to use the RawMIDI API, or a tool
like amidi.
I wanted to avoid using the rawmidi API, as it requires exclusive access to a
MIDI port, so you couldn't send SysEx files to (or receive from) a device while
it still is connected to another app.
I will continue to use RtMidi ATM to get some code written. If I'm pleased
with the code, I will decide how to cope with bigger SysEx events.
Thanks a bunch for all the useful replies!
