[PD] SysEx In issue

[Lucas Cordiviola]

I did a test patch (attached)

- I can send 7 byte sysex messages up to every 3ms

- I can send noteout up to every 2ms

This tests gave same results if using a midicable (cable loop on the sound-card) or using a virtual driver.

It is most likely a bug, maybe introduced in the MIDI overhaul I did for 0.48. Does the same issue occur in 0.47?

Can make a *re-produceable* patch and/or project for testing and open an issue on the pure-data Github repo? The simplest thing for me would be the syses messages you're sending as bytes.

You could also check the output of the midi tester patch I added:

Hi,

Not too long ago I wrote here reporting an issue with receiving SysEx
messages.
When Pd receives a big quantity of SysEx, the MIDI IN port 'gets stuck' and
then you need to go to 'Media->MIDI settings...' and re-select the port,
otherwise no MIDI messages will be received anymore.
Here's a video that shows the issue:
https://vimeo.com/316526250
it's a private video, the pass is: sysexissue
Does anybody know what could cause this behavior and if it's possible to
'fix it'?
The first time I reported it, it was when I stumbled on this using my
personal Linux machine and Miller Puckette suggested to change the MIDI
buffer in the source code, but unfortunately also setting that to something
insane like 2^20, the issue was still there.
Now I double checked on MacOS Sierra and Windows 10 and it is the same.

Cheers,
Mario
