Hello Philippe,
thanks for your answer and your kind words about my music. No I hadn't
received a satisfactory answer to that question yet. For a given value of
"satisfaction" this answer doesn't qualify, but that is definitely not your
fault. I should dig through RtMidi and see where this happens and find out if
I can implement something simple that works. :)
Best wishes and a happy 2022 to you,
Jeanette

Hi Jeanette,
Before anything else, let me know I enjoy reading about and listening to your work.
People like you keep this community exciting.
Did you actually get an answer already to your question below?
The theory is simple. When a alsa midi connection is opened in non-blocking read mode,
you'll receive MIDI bytes in groups of 3 or less. A MIDI parser chains these bytes
together until you have a full message and then handles it to a callback or handler or
queues it for a read function. As soon as the parser receives a sysex start (F7) byte, it
knows a sysex message is pending.
My two cents is that you’ll need to dig into the rtmidi source code and figure out where
the test for sysex start (F7) byte is happening, and implement ad-hoc actions
accordingly.
Best wishes - may 2022 not be 2020 too.
Philippe.

Hey hey,
is there any way of finding out whether a big SysEx message is incoming, before the
normal callback is invokved or I suppose one of the buffers is full? May it be viable
reducing the buffersize (version 5.0.0) and increasing the number of buffers? The manual
for this function mentions that this will not change anything on most APIs, since they
handle buffers internally.
Many thanks for any pointers!
Best wishes,
Jeanette
