MOD Duo X - Last mile countdown

Marc · July 8, 2019, 6:58pm

It just appeared on my desk. I was ready to wait a few weeks more, but here it is - serial number 4, and I am happy as a boy can be.
Let’s see what this beauty can do for me. First impression: this is going to be a lot of fun…

Lookin’ good!!!

The Duo X comes with a selection of CV modules to fulfil all of your modular dreams.

is there more info or larger pic?

falkTX · July 10, 2019, 9:39pm

We will be releasing the CV related plugins in 5 days.

Hallo MOD Jünger,
zunächst einen großen Dank und Respekt für das Zustandekommen des Duo X.
Ich bin neu hier und Besitzer eines MOD Duo X (Seriennummer 006).

Nach Zuhilfenahme des Wiki Troubleshootings bekam ich die Zauberkiste zum laufen, hatte aber leider ständig abstürze in Form von einfrieren und nichts geht mehr, sowohl im Web Bereich, als auch Stand alone. Ich hoffe das sich das mit kommenden Software updates erledigt.

Hat jemand auch bereits ähnliche Erfahrungen?

Viele Grüße aus der Hauptstadt
Doc Slyder

Hello there, welcome to the forum.

Please keep the conversation in English, so everybody can follow along.
(Ich kann ein bisschen Deutsch verstehen, aber nicht anderes leute)

Are you able to describe what is your use of the unit?

We are going to be pushing updates frequently, yes, but I am not confident enough to say they will fix your issues.
Which system/PC do you connect the unit to? (windows, mac, something else?)
The more information we have about the issue, the better chances we have of understanding it and fixing it.

Doc_Slyder · July 11, 2019, 9:34am

OK, we continue in English and I try to make my problem a bit more concrete.
I have a Windows 10 system and so far I have connected a Döpfer Dark Time / Dark Energy 3 to Input 1 and via Midi In the Duo X gets the desired BPM.
From Output 1 it goes into a Behringer X32 digital mixing console.
The connection works, even the BPM will play correctly and the website I get connection.
But the Duo X freezes regularly and the connection to the website as well.
Even without a connection to the web, the device freezes after a short time.
Only after a restart of the Duo X is it again, but unfortunately not long.
I hope you can do something with it, because I like to help improve the magic box.
Greetings from Doc Slyder

Thanks for the feedback. I have some follow up questions.
You are connecting the MIDI from the “Dark Energy 3” into the Duo X, to get MIDI sync going correct?
Are you using the MIDI DIN cable?
Assuming that device can send MIDI over USB, please try that instead of using the MIDI DIN ports.

Also, if you disable sync over MIDI, do things work better in general?

My guess here is that something is going wrong with the MIDI sync mode inside the Duo X.

Doc_Slyder · July 11, 2019, 10:20am

Hello and thanks for the quick reply.
All my devices (Behringer Model D and Neutron, Arturia Drum Brute, Novation Peak and Bass Station 2, Döpfer Dark Time and Dark Energy 3 and Akai Advace 49 and MPX16) are connected via Midi DIN cable and I would like to keep that.
I will try if the Duo X works better without a DIN cable and will report you.
But I can report back at the weekend at the earliest.
Greetings from Doc Slyder

…watching this closely… i don’t yet have my Duo X, but sync via MIDI DIN is important for me as well, for some of the gear i’ll be working with.

falkTX · July 11, 2019, 1:07pm

It is a tricky situation. MIDI sync fluctuates a lot, due to the low resolution of MIDI messages and their timing. Most plugins do not handle well the (tiny) change of BPM every cycle.
But we will do our best to find a working solution.

Doc_Slyder · July 11, 2019, 1:26pm

I am glad to hear that you are looking for a solution and hopefully will find it.
But I’m confident because others have already done so.

Marc · July 11, 2019, 1:55pm

MIDI Sync is also important to my planned setup. I currently only use MIDI in using the DIN cable with no problems at all. I had some crashes of the Duo X when I started it, but after changing the pedalboard loaded and playing around with the device for maybe 30 minutes, no cashing anymore. I dod not report it because it never happened again and I do not know how to reproduce or force a crash. I’m keeping my eye on this and will report as soon as I have more info…

Doc_Slyder · July 13, 2019, 6:40am

So, it looks like the freezing of my Duo X is not due to the synchronization with Midi DIN or Midi USB!
I set the clock source to Internal in the settings and removed all midi cables from the device.
Only input 1 and output 1 are occupied and nevertheless the device freezes after a short time!
It does not matter which bank and which board I call.
Does anyone else have an idea?

Just got my duo x. Oh Man what a lovely and great engineered device:) thanks for all your hard work!

falkTX · July 13, 2019, 12:55pm

Might be a specific plugin causing this, did you enable the beta plugins?

In any case, we will be releasing v1.7.1 update early next week, as we already have a few bugfixes.

maxman · July 13, 2019, 1:06pm

Almost everything works fine now for about an hour.
Just couldn’t get USB Host Midi to work. Using an Arturia Keystep. Using normal Midi-DIN Cable works perfectly. Looking and dmesg and lsusb nothing seems to be there or mentioned regarding USB -Midi/HID devices. any hints?

cheers max

falkTX · July 13, 2019, 1:51pm

Could be the “aggregated midi mode” not catching your device somehow…
Connect the MIDI device after the duox boots up, run jack_lsp -c inside the unit and post here the output.
Thanks!

also red lines a problem?
