Different MIDI in/out devices Norns

[RPLKTR]

@tehn

Tracker is asking for a 1A supply. that doesn’t mean it uses all of that, but it could.

Under normal operations Tracker doesn’t draw more than 450mA. We don’t use extended USB 3.0 Power Delivery amperage.

The peak moment for power draw is at the device’s power on. We’re bundling a 1A power supply with Tracker to give ourselves some headroom. Since we don’t manufacture power banks we recommend fast-charging power banks as the smaller ones which should theoretically be 5V 1A capable often aren’t even close.

[tehn]

that’s good to hear, and impressive the device only draws 450mA.

that’s within spec, so provided you’re not using several other high-power USB devices on norns, this could work.

however, i’d highly recommend powering it separately and just using a usb-midi converter.

[TheTechnobear]

Presumably you could also use a powered usb hub in between norns and tracker. (*)

this is an approach I use on things like Organelle when I want to plug in power hungry devices , as I don’t have a power/data splitter

————
Many powered hubs can deliver a lot of amps - but obviously check yours !

[MUNINN]

is there by any chance that is possible to fix this bug and show all the available midi ports?
i’ve got a uc33 that is capable to act as a midi interface, but only on its second port. would be nice having a controller and a midi- usb interface in the same box, actually…

@MUNINN

show all the available midi ports

16 vports comin’ up

PMAP autosave + 16 MIDI vports

re: the double-port devices, there was some debugging info requested which i couldn’t find reported back:

@okyeron

it might be worth looking at lsusb -v to see how the devices are presenting. Then also if the second device is showing up in ls /dev/snd/

if you can add these details, that’d be

[simonvanderveldt]

This should already work. Are you using a vanilla norms? Which software version?

[MUNINN]

I’m using a fates running the latest update. Just tried to Connect the uc, seems to see only the first port

[simonvanderveldt]

Probably best to report it on the fates repo on GitHub or the fates topic here then.

[MUNINN]

I will do! Think i’vedzone it months ago and this feature wasnt available actually.

[MUNINN]

ok so update!
i was talking with @okyeron about this thing of the uc33 and he told me to post here.
so after ssh into fates i did run :

aconnect -l
client 0: ‘System’ [type=kernel]
0 'Timer ’
1 'Announce ’
Connecting To: 128:0
client 14: ‘Midi Through’ [type=kernel]
0 ‘Midi Through Port-0’
client 20: ‘UC-33 USB MIDI Controller’ [type=kernel,card=1]
0 'UC-33 USB MIDI Controller MIDI ’
1 'UC-33 USB MIDI Controller MIDI ’
client 129: ‘Client-129’ [type=user,pid=471]
0 'Virtual RawMIDI ’

amidi -l
Dir Device Name
IO hw:1,0,0 UC-33 USB MIDI Controller MIDI
I hw:1,0,1 UC-33 USB MIDI Controller MIDI

while the uc 33 was plugged in norns. as he assumed from amidi, the uc 33 has multiple different ports but somehow norns don’t know what to do with them.
can you guys help?
i feel is doable!
please don’t let me buy a stupid usb to midi box

FWIW here’s @MUNINN’s output from lsusb -v

[simonvanderveldt]

What does cat /proc/asound/cards show?
And assuming card0 is the builtin soundcard, what do cat /proc/asound/card1/id (just to check it’s the correct sound card/your MIDI device) and cat /proc/asound/card1/midi0 show?

[MUNINN]

don’t have any clue what you are asking me… please treat me as a professional noob hahahahah
what do i have to ssh to, i assume, navigate to the location you’re asking me?
edit:
shows up this

[simonvanderveldt]

Just do the same thing as you did for the info you posted here Different MIDI in/out devices Norns

Once you’re connected to norns over SSH run cat /proc/asound/card1/id and cat /proc/asound/card1/midi0 and post the output here.

[MUNINN]

sorry for the late response! here they are

[simonvanderveldt]

Thanks. There’s a part cut off from the bottom, could you post that as well?

[MUNINN]

there is not, it ends here

[simonvanderveldt]

I guess that’s the problem then? Either it’s not presenting the second port as a full port or norns requires an output on the port and it doesn’t have any.

[MUNINN]

it is weird, actually. as i’m watching right now my uc 33 shows up as a 2 ports controller, but only in the input section; otherwise is shown only the first output port (???)

hope to do a hard reset of this controller and starting again. something is weird on this machine.

[MUNINN]

so, update!

this thing is going really nowhere near my understanding. as following the manual, i have “unlocked” the midi out from usb and finally norns is sending midi data!
still, after doing a factory reset, i can’t receive any midi data cause of this damn thing of the second port (which is still available on my computer but not in my norns)
guess as soon as i don’t really understand how this controller should work, this thing end here. at least now i’ve got midi out!
probably going to build an arduino midi interface/ controller on my own.
thank you all for your support! if something pops in mind please let me know
