Hi, sysexin does not seem to work on Mobmuplat, at least not on my devices.
can anyone confirm this?

@bang Pretty sure mommuplat will only use vanilla objects.
But sysex is midi..... so strings of values.
I suggested this https://forum.pdpatchrepo.info/topic/13662/raw-midi-midiout/5 a couple of months ago for sending out sysex messages using [midiout] and there are other threads like this...... https://forum.puredata.info/topic/377/sysex/33 that also use [midiout] to send sysex messages.

I would test first whether Pd [midiin] receives any data when a sysex message is sent to its channel. If not then you are probably out of luck..... but if the message is received at [midiin] then you can use that with mobmuplat and build something to decipher sysex into your patch.

[sysexin] and [sysexout] are vanilla.

In Linux, there is a size limit on MIDI packets (512 bytes). Large packets do not appear at [midiin] or [sysexin] outlets.

I could not find whether Pd's PortMIDI usage (which seems to be used for both Mac and Windows) has a similar size limit.

I don't know about mobmuplat -- but, I can say for sure that there is at least one supported platform where, if your device sends sysex beyond a certain size, you won't get it -- thus, Pd can't claim to make a 100% guarantee that large packets will be passed through.

https://forum.pdpatchrepo.info/topic/14028/send-syx-file/11 outlines a test case.

I did a few more tests: [sysexin] and [midirealtimein] still don't work on mobmuplat.
[midiin] does! But it suppresses the startbyte 240(f0) and stopbyte 247(f7).
So let's see if I can deal with that.

Thanks for your input

[sysexout] isn't.
Anyway, I moved to pd on a Raspberry.

Ah ok... Come to think of it, there is no need for sysexout anyway because it's trivially easy to add the beginning and ending status bytes in the patch.

If you run into the size limit, you could change the alsa max packet size and rebuild. Hope that's not necessary though.
