Rappel

Hello. I want to warn every potential raspberry Pi5 buyer, to think it twice.
Becuase it introduced the rp1 monitor chip, changed Pins allocation, 99% of old libs do not work anymore.
The most famous DIY Synth using raspberry Computer module Pi5 at its core, is having lots of problems adapting
broken libs to make DIN MIDI work, and to many DIY Zynthians users, that don't have the full Zynthian V5 package,
things don't go well.
I recently bought a Slim Midi Hat just to get Midi In OUT. My previous 6N138 simple Octocoupler circuit didn't work
so I bought the Hat thinking it might solve my problems, but only PiSound HAT, that passes MIDI through an ARM chip with SPI
protocol seems to work for non full Zynthian users. All others don't have DIN MIDI WORKING.
On Bookworm it's even worst. Every lib has to be rewritten, most libs simply has been written to work for all Pi untill vers 4B.
No guide has been updated to say instructions won't work on PI5, so even basic google search will give you results for older Pi, not Pi5.
And none works. The most important part, GPIO lib, WiringPi, lgpio, GPIOZERO and others, still works on PI ZERO, PI3, 4... but not
one specify they will not work on Pi5.
Be careful if you wish to build anything with a Pi5 as your base module.

DIN MIDI problems with RPi5 (RESOLVED)
I quick internet search reveals Cre8Audio released a firmware update last year to make the device Class Compliant. https://www.youtube.com/watch?v=Kn87Sf1PCuA This should work on a pi.

My Hybrid Pi5 DIY Zynthian experiment
I could try take away the pi52 DAC… and try connecting only the Slim midi hat, to see if thtt makes any difference… let me try this now… I connected my jetli usb sinilink soundcsrd but it is not bein grecognised. It is recognised automatically in Pi os. No more pi52 hubrid nvme da. Still no...

Zynthian 4 upgraded with Raspberry pi 5!
Yeah, I don’t think I did anything but upgrades, but I might have tested various configuration options for the screen and sound card back and forth. I was using an early Pisound for the soundcard initially, which needed upgrading, so at one point I was unloading and loading modules and...

MIDI issues with RPi5 and Pisound card
I wasn’t that successful. On Sunday I played around, connected the Pisound to the Raspberry Pi via the Butterfly gpio two header and cable. And wondered why the Pisound was smoking. Somehow I forgot that the pins on the Butterfly header are crossed. So I put 5V into a pin where it shouldn’t be...
