Thank you goldenarpharazon and mschnell

If you are sending MIDI over USB then anything is perhaps possible with buffers and fast streams.
Here are some suggestions to help:-
SysEx messages are only sent/received via USB. Using the consoles 5-pole MIDI connectors and SysEx is not possible. I didn't know that before. (So, my final plan to use an Arduino ÁC as "gateway" are foiled anyways...)

I think I've hit the limits on receiving SysEx with OSCII-bot.

Hm... Currently I'm not sure if I want to invest more time when these are the limits of OSCII-bot. My plan was also to use the console meter data and then there's much more data to process.

That's what I thought at first, too. But it makes no difference if MIDIOX is open or not.

time_precise() shows that there are only a few Ás between the messages (see screenshot). But one time there's a step of several ms! I think that's the point when full receive often fails.

I suppose OSCIIBot will only hit limits speed in very rare cases.

EEL is a compiled language and super fast, as it's designed for realtime audio calculation.

So if you have some not too exotic EEL software in OSCIIBot between USB-Midi and a Network, there should be no practical problem.
I agree on sending (see screenshot) SysEx but not on receiving.

Time between Rx messages:

Time between Tx messages from OSCII-bot:
