Re: Ultralite AVB

I sent an email to MOTU asking if they were aware of any issues in regards to channel drifting on the 828es over USB 2.0 connections, and they said that they were not aware. Has anyone been in contact with MOTU support regarding this issue? @shellwalker? They also could not give any guarantee that ...

Re: Ultralite AVB

64 channel mode is working just fine when the necessary kernel changes are applied and the curl command executed. However executing the curl command must be done over the ethernet connection. Unfortunately the USB connection uses in its commands some unknown 4 bytes, my guess it is some crc32, and ...

Re: Ultralite AVB

Digging a bit in the filesystem... found the json file with the anoying arbitrary channel limit. /opt/DeviceDescription/dd_UltraLite\ AVB.json "MaxChUSB2": "64:32:24", "MaxChUAC": "24:24:24", I hope there is a way to inject better values and get the bang for t...

Re: Ultralite AVB

Really nice to see major traction regarding our "beloved" Ultralites Will all new information about the device in any way help us get network access to the device over usb ? using localhost:1280 it is not that important compared to the audio glitches but would be helpful for users with mor...

Re: Ultralite AVB

Hallo, I have a question about the Midi connectivity of the Ultralite AVB. I am not sure I should open a new thread in the forum. Please apologize if this conversation is not the right place to discuss it. I have plugged a midi controller (a Rolad F-120 Keyboard) to the audiointerface but I cannot ...

Re: Ultralite AVB

My findings for someone that needs higher channel counts over usb with linux If you have the "old" version of Ultralite AVB, downgrading firmware to 1.2.8+378 will unlock the "USB Mode" drop down menu. If you run samplerate 44k1 or 48k you can change usb channels presented to hos...

Re: Ultralite AVB

I bought a brand new Motu 24Ai a few days ago to expand my AVB rigg and check if the same problems were present as with my Ultralites. The box came with firmware 1.3.2+922 and was working well with my stock Ubuntu studio laptop. I did try to go back to really old firmware to be able to run more than...

Re: Ultralite AVB

Hi LinMusicians, I own a good working 828es and I'm going to buy a Ultralite AVB or a 624 AVB with a switch. I'm using the first firmware on AVL-MX or Kubuntu 20.04. I use to wait the turning on of the interface, then I turn on the laptop (Acer Nitro 5). I can do some tests but I need to know exact...

Re: Ultralite AVB

Alright, sounds good. Yeah, I wouldn't want you to be in a situation where you had upgraded to a new firmware in anticipation of this patch, found it didn't work, and then couldn't downgrade. If you're able to downgrade then I think you're in the clear. -w Ok, yes, downgrading is fully supported. W...

Re: Ultralite AVB

So, the behaviour I was observing with Audacity turned out to be resolved by a BIOS update, so that may have been a sketchy USB host controller. Regardless, even with the BIOS updated, I was seeing channel drifting after hours to days of operation with linux-next. With "acpi_irq_nobalance nowa...

Re: Help me get back to a functional DAW (Xruns Galore)

I have been running linux and Ardour since long time ago and x-runs and tweaking has been an ongoing battle. I am using both FireWire and USB and tried all kinds of computers and newer laptops seems to be a lot harder to successfully run with low latency. Running Ardour with just alsa seems to work ...

Re: Ultralite AVB

The UltraLite AVB's mixer is accessible via web browser. I guess on Windows and Mac they use ip-over-USB. I don't know if and how this works with Linux. Plug your UltraLite AVB's ethernet interface in and see on your router which ip address it gets. Then use http:// with that address. I configured ...
