Hallo all.
I have a SLIM MIDI hat, which does both MIDI and I2c with mcp23017 ic. with a breakout
that can support up to 4 encoders and four switches.
I was experimenting with a Pi5 but GPIO libs were broken, Kernel Baud rate would override
my usr or boot config baud rate setting, and could not make TX and RX pins nor read nor write
MIDI with the SLIM MIDI Hat.
PS: my 4C+ is set to arrive by next week, I’m preparing the set up instructions from zero.
---- How to setup—
First the OS, Debian Bullseye or ARMbian OS?
KXstudio repos has Cadence, catia, Jack, ALSA, Pipewire. The whole set
in practice to make MIDI work on the software side.
for the hw side, Idrolez, the maker of the Hat, compiled this github ttymidi library for the rpi4
and provided instructions for set up also
After this I should be able to plug in the Hat and communicate with it, in theory, at least for the
MIDI part of it. Is there anyone that knows already how all of this works and can give
me a hand for compiling a complete setup process from start to finish?
I don’t know yet all the quirks of the Rock 4C+, I worked on Bookworm for the Pi5, and
have a Linux laptop with Debian KDE-GNOME Nobara 42, I also use it for making
music, with a Bitwig licence and a whole bunch of VSTs and Lv2 loaded with
Cadence, Catia and Carla rack. My hope is to replicate it on the Rock 4C+, with
the added value of the DIN MIDI (and the encoders, next).
