MIDI interface locks up machine totally when inserted

[clusteruk]

So as I have AE4 recording and editing brilliantly I thought I would try and setup a MIDI keyboard.

Plugged in my USB interface and machines locks up, display OK, not nothing moves and have to power off.

If I plug in at boot it will launch grub and start but then nothing.

I bought a new USB to midi cable but same result.

Keyboard, mouse and data drive key work ok.

Any ideas?

Sorry, only questions as response:
- USB version ?
- Are you using a hub ?
- How many USB headers are present on the machine ? Have you tried different ones ?
- Are you able to get further when you unplug everything else that is connected to USB ? (fresh reboot with everything unplugged is best testcase)

I have no experience wrt AROS and midi so can't tell if things should work to begin with. Above questions are more generic ones that in my experience /can/ cause issues

Not using a hub, 4 USB headers, I have tried 2, rebooted with and without midi connected. If I disconnect MIDI and reboot all is good.

MIDI is not implemented on Aros missing the Camd driver, it may be that your interface conflicts with the system

[Amiwell]

Alfred Faust intervened some time ago here, but he was unable to fix the problem of MIDI implementation, it seems to me because the original Camd driver is written in assembly

[magorium]

camd and isochonous transfers last changes seem to date from 2021. I don't think they are (back)ported (yet).


You could try and see if you got any improvements with ABIv1 (assuming you are now testing on ABIv0)

[Amiwell]

Magorium Kalamatee seems to me that he worked on the USB class but is not implemented on Abiv0

[magorium]

@salvo:
Yes indeed.

That is why I mentioned that it might perhaps work better for clusteruk with ABIv1. At least it would allow him to test if his device works with AROS.

I understand that this probably wont help clusteruk on the short run but in case his goal is to gather information on what "work" needs to be done then he can at least test this part and in case his device works with ABIv1 then he does not have to spend time on the subject other than to keep in mind to have these changes back-ported at some point in time.

Yes indeed Magorium when the problem no longer exists Alfred Faust has made itself available to fix bars & pipes

[clusteruk]

This is a good point, Bars and Pipes is on AROS and it only work with MIDI.

Is this a non starter or a speak nicely and offer gifts to get tweaked?

I don't know if any programmer in our community could solve all this
