Midi clock out patch how to


#1

Hi there,

this is my first post, although I got the Axoloti since the end of kickstarter :smile:
Basically what I wanted is to realize a midi clock output to start and synchronize some of my other hardware gear, and because I am into hardware electroncis, I am of course interested in the whole axoloti board.

But sadly, ok to admit I only tried for less than half an hour, to establish a midi clock out, but it didnt work, I only had one patch in my file, the midi clock out, do I need a start? a trigger a out? I put the patch on din ( is that correct? ) i want the midi port out of course to shoot out the midi clock so start all my "slaves" playing music.

So I hoped any of you have realized a midi clock out and can help me out here a little.

Ah and one more error appeared, I will copy and paste it later at home, it says USB is connected but i cannot go live, I fear a little bit that something is broken, but will try to flash the firmware again later, could all be one problem or 2 seperated ones, I will find out soon.

And just for interest I want to have the korg esx 1 on the midiclock, and maybe later some more midi samplers sp 404.

Thanks for your help.

You will need a ctrl/toggle object to start the clock. You can choose DIN in the dropdown if you are using a regular USB cable connected to the MIDI device you want to start. The dial on the midi/out/clock object is used to control the tempo.

I've tested this patch with the Korg Volca Beats and everything seems to work fine.

Thanks a lot also for the screenprint effort.

So I need a control toggle , I guess I can put that on off with the mouse during live mode.

the diplays you onlz put there to see the actual count, right?

So I dont wanna use USB out, since I use the USB only for programming and access to the axoloti pcb.

But I guess I just trial and error for the device outpput until I hit the Midi out on the board.

Thanks.

The toggle can indeed be used during live mode.

DIN is the correct output if you want to use the midi out port on the board.

The display objects are useful for debugging/testing, but are not needed for the patch to work.

why trial and error? I thought its pretty clear, no?

din is the midi din output (check underside of board for in/out markings),
usb host is the usb host port, the bigger one you plug usb devices into (i.e. axoloti is hosting the device)
usb device is the micro usb port, used when the axoloti is acting as a midi device. (which is does when connecting to a pc for example)

(host/device is standard terminology for usb)

Id recommend reading the user guide, it explains things like types (booleas, floats etc) ... also check out the tutorials and help patches.
patching is not difficult but obviously does require a bit of learning.... easier if you have used nord modular/reaktor/max/pd but its difficult.

to test the board id highly recommend you run a demo patch, so you have confidence everything is working.. again there is a step by step guide in the user guide.


Midi to PC over micro usb doesnt work for me

Thanks for promt answer.

Yes I did that demo device like 2 month ago, then had no time or lust to continue and now starting to get back on track again.

I am electric engineer so I can tell an usb connector from a Midi one amongst other maybe :smile: more advanced stuff.

What confused me a bit is the DIN, has the input in it and I want the midiout, but your explanation was pretty clear so thanks again.
And I am aware that I am still at the beginning, so my questions are pretty basic, so I appreciate your effort of answering them anyway.

I hope I can experiment and use the axoloti from now on more frequently and keep you guys informed.

so axoloti has 4 more midiports over micro usb?
how to access them? they are not showing up on my Pc...


#8

No, when a device is plugged into the axolotis usb host port, then it can expose 4 ports to the axoloti.
(i can do more, but i thought 4 would be enough, as id only see 2 so far on a usb to midi din adapter i have)

theoretically, the axoloti firmware could be changed to expose more than 1 port to the PC, on the usb device.

but cant really see a use for it, its typically used when 16 channels are not enough.
(so in the converters example above, its because there are 2 physical din which can act as in or out, and obviously each can carry 16 midi channels)


#9

so one port is exposed to the PC? How to access it? i hoped it will show up in ableton, but it doesnt...


#10

you dont get get an axoloti midi device showing up?

you should do ... do you see the midi device in the device manager? (I assume your using windows).
when axoloti is installed, it exposes to devices over USB, the midi device and the bulk device. (the later being used to communicate with the UI) .. so on PC/Mac/Linux axoloti looks like a class compliant USB midi device.

if thats not happening, probably best to create a new post in the helpdesk, with details about your setup, what is working and whats not. in particular a screenshot of the usb device entries in device manager would be useful.
so... you've never been able to send midi from the PC to axoloti, or did you do it via the USB device listed in the preferences in the old version of axoloti?
