Akai MPK mini mk3 driver

[oscaracena]

I’m not sure if it will work with that version… Not at least without a bit of rework…

[wyleu]

I don’t doubt it but we can at least how far we can get. You have defined much useful interface.

Hi guys, I am completely new to Zynthian just built my box with a pi4 and a touchscreen and was interested in integrating my very own akai mpk mini mk3 to. Does anyone know how can I pull the changes made in this thread into my local zynthian installation ?
many thanks in advance to everyone

[oscaracena]

Hi @fedepoi, and welcome to Zynthianland!

I’m pretty sure that @jofemodo is checking the PR just now, to include it into Oram (which is the ‘testing’ branch of Zynthian). You can update to Oram, and then wait for the changes to be committed.

Or, if you can’t wait, you will need to apply the patch of the PR (I can send it to you) to your installation, but those changes will be lost on the next update. It’s your choice

[fedepoi]

hi @oscaracena thanks for the quick reply!! I’ll switch to the oram branch just now (I am assuming I should switch to oram in all the repos and not just zynthian-ui right? ). would be also really nice if you could send over the git patch to apply just to test this out I’ll then update the system once pr 496 is merged

Better is make new installation on other ssd card.

New testing image Bookworm Oram 64bits

Hi @zynthianers! I just uploaded a new Bookworm Oram 64bits image: https://os.zynthian.org/test/2024-03-01-zynthianos-bookworm-aarch64-oram-2403.zip It’s a testing image, not production ready! It fixes a lot of things and it’s quite usable, although you will find issues, of course: webconf terminal works again webconf MIDI log works again wifi is now configurable from the UI. Probably buggy as it’s very new. it should auto-configure V3, V4 & V5 on first boot hopefully, it should auto-conf…

[oscaracena]

Yes, as @ToFF said, you will be safer doing a whole new installation (bookworm is 64bit too). As per the patch, here are the instructions. Run these commands inside the folder /zynthian/zynthian-ui:

wget https://patch-diff.githubusercontent.com/raw/zynthian/zynthian-ui/pull/496.patch
git apply 496.patch

And restart Zynthian

[fedepoi]

Amazing !!, thank you both guys

[oscaracena]

You may find another problem, as the driver loader does not expect an auxiliar module in the ctrldev folder (and I add one). To fix it, apply this other patch:

diff --git a/zyngine/zynthian_ctrldev_manager.py b/zyngine/zynthian_ctrldev_manager.py

@jofemodo, you may need to add it too, or shall I update the PR with it?

[jofemodo]

@oscaracena, please, update the PR so it’s complete

@fedepoi, muy bienvenido al carro de zynthian, compañero!! Welcome to zynthianland!!
If you can wait a little bit, i hope to commit the @oscaracena MPK driver in a few hours

Cheers!

[oscaracena]

Done!

[fedepoi]

@ToFF @oscaracena I flashed this image on a new sd card but seems like the default raspberry password does not work to login into the webconf tool (it does not even work for sshing into the pi) anyone knows if there is a different default password for this specific image?

[oscaracena]

Try with opensynth.

[fedepoi]

@oscaracena

opensynth

yeah ! that worked thank you so much

[fedepoi]

@oscaracena I can cofirm that the patch works as expected, great piece of work there it integrates the midi keyboard perfectly! well done.

not sure if you guys are aware but wifi connection seems to be broken on this branch I also tried to connect manually seems to be working when pinging 0.0.0.0 but then after opening zynthian it says can’t connect to wifi. probably this is an issue to raise within this other thread though (New testing image Bookworm Oram 64bits)

[riban]

Did you update? (With Zynthian connected to Internet.)

It works for me. Could you give more details? What procedure do you follow to connect?
Do you use “strange” characters for the network name or the password?

@riban

Yep! @fedepoi , first thing you should do with the new oram image is update

Regards,

[fedepoi]

@riban yeah I did the update, ill redoit just now to be on the safe side.
@jofemodo not any strange sign for the SSID name or password. not sure what is happening there. looks like the pi itself is having issue to connect to my wifi. should I also do a full system upgrade with apt upgrade ???

[riban]

@fedepoi

should I also do a full system upgrade

NO!!! The Zynthian update mechanism does tried and tested updates. Manual updates may break it.
