I also have ttymidi-sysex installed, and I can see Midi in and Out ports. I tried Bento-ttymidi out of desperation...I confirm! The bento code seems to be buggy since it tries to set the baudrate to 38400 and then 31250. Moreover the code does not handle Sysex properly.So you either try to set a custom baudrate using the UPF_SPD_CUST feature to get 31250 baud or you use the overlay and ask for 38400 baud. With the overlay, that whole set_custom_baudrate function in the bento_ttymidi bridge is unnecessary.
because I couldn't make ttymidi-sysex work anyway with the normal overlay method...
And because I have reverted back to a Pi4, I thought that also it would have been easier since there should not be
any need for venv ttymidi syswide install methods, as those implemented by Zynthian, have been made for Pi5 specifically...
I could open an issue on github ttymidi-sysex also, or just uninstall bento.
I flashed a new Usb with bookworm 64 bit and ran all the rpi-updates this morning.
I can reflash everything once again.
I have Bullseye installed on the Sd card. First it was ttymidi-sysex only, then reflashed and tried bento...
At least someone acknowledge that I'm not fantasizing here... ty!!
PS: People started having issues with Midi uart in 2018. Whatever caused the old methods to go belly up, it's still there.
I would like to get a time machine of a pre-2018 Raspbian OS, with all relative libs of that timeframe.
Check if it's working. A single kernel update, or lib update past that, must have broken something.
I would need special powers I don't have to be able to get back in time.
I checked if there were archives for all the libs. There aren't.
I would need an image dump of an OS img that hasn't updated ever since, then try update one single lib at a time
for exclusion, untill the midi don't stop working. I don't see how this can be tackled otherwise.
It was working for thousand of people back in 2018. Midi Hubs videos, guides, instructions....
This is what I can do personally. Testing. If anyone has an old Img link that I can test I'd be very
happy to go on. A clone.
