Hi loujudson,

I have a stylus, tried it before for drawing, was not a big fan, but will try it again with the motu, maybe it helps.

Thanks for the tip,

RJB

Eep! Definitely not intentional. I've reproduced it in house and I've filed a bug on your behalf. For now, I guess the workaround is to leave a tab open.

The manual has a bunch of detailed info: http://cdn-data.motu.com/manuals/thu...Manual_Mac.pdf. In particular, check out the page showing the front panel near the beginning, item #2 :

"The upper phone jack is a standard quarter-inch stereo headphone jack. Its output is hard-wired to mirror the XLR main outs on the rear panel. From the factory, the MAIN VOL knob next to it controls the main outs and this jack, but MAIN VOL can be programmed to control any combination of outputs. See “The Monitor Group” on page 91 for details. Push the knob once to view the current volume setting in the LCD display; push it again to mute the monitor group; push a third time to return to the previous volume. Note: if the Monitor Group is programmed to not include the main outs, the MAIN VOL knob will no longer control the volume of this phone jack, either."

The bottom phones jack is configurable, however (see item #16 on the same page).

When you can't grasp something and rotate it it doesn't make a lot of sense even though it's "traditional."
The knobs actually respond to input linearly, not radially. That is, they already behave like sliders, dragging horizontally or vertically rather than in a circle.

I agree knobs are a little wonky on computers because they're imperfectly mimicking a physical analog. Not having to do a radial drag, though, makes them much more useable. I also find them to be more "glance-able" and visually intuitive. I have an easier time getting a sense of how everything's panned with knobs, especially when channels are panned somewhere other than hard left, right or center. I'd be curious to know if other people feel similarly or not.

The screen real estate is important, but as we work towards being finger-friendly, having a bigger control is actually helpful. Some of us have fat fingers that make small widgets hard to interact with. As well, there already are sliders just below the pan section, so you'd risk confusing them.

Anyways, that's part of our reasoning behind the knobs. Happy to hear more thoughts though!

Yes, I have the same problem. MOTUAVBHTTPServer.exe adds about 15-20% CPU load which is enough to push my CPU cooling fan into overdrive and adds a lot of extra noise. Very frustrating. I love the interface though, so I may end up buying a liquid cooling system to compensate. Hopefully MOTU can get this fixed quickly.

I thought the HTTP server was on interface but when I launch the GUI it connects to localhost. Perhaps mrmiller would clarify for me?

We're looking into the issue and hopefully I'll have something to report soon.

Yes, the server does run on the interface. If you're connected via USB or Thunderbolt rather than ethernet, you need some way to access that server. We run a proxy server on your computer that forwards requests to the server on the interface via USB/TB, and that's what MOTUAVBHTTPServer.exe is.

Here's another workaround other than leaving a tab open, in case it helps. If you don't need to access the web interface for a bit or you're connected via ethernet as well, you can temporarily disable the forwarding server via the Services program. Scroll down to MOTUAVBHTTPServer, right-click and select "Stop." Doing the same and selecting "Start" will restart the server, as will a restart of your computer.

Perhaps it would be usefull to select it in the driver/settings windows like "provide a hhtp Proxy per USB/TB" - so I could enable/disable - me in my part, I will use one notebook for the DAW and another notebook to control the 1248 ... so I don't realy need this.

There's a bug right now causing it to hog CPU while idle. Once that's fixed, the server's footprint is very small so you shouldn't even notice it running. Are there any other reasons beside the current CPU usage bug that you might want to disable it? Just to reiterate, if the proxy server isn't running, the interface won't show up in the AVB Discovery apps and you won't be able to access the web app from any device unless the interface is connected to the same network via ethernet.

I have to say, I continue to be impressed by this new direction Motu have taken with producing higher end products and maintaining such a strong presence here helping and fielding questions.

I don't know what brought this on, but it's good to see and I hope it lasts!

MrMiller - can you speak to the low end roll off of the Motu unit outputs (1248, 24Ao)? I have home theater subwoofers easily capable of sub-10Hz output and hope the Motu gives me the full frequency spectrum on output. Thanks.

If I can enable/disable it, I can control if this process is running or not. If I connect per ethernet/wifi only - I don't need this process

I only think of keeping the system small and stable - only necessary processes should run... if it is "calm" if no http-traffic is used, it should be ok, but the option to disable (like a xampp "Stop" and "Start" button :-) ).

BUT more important than this buttons are in my opinion variable input/output configurations up to 48 or more inputs like mentioned before, would be great:

e.g.

24 In / 24 Out
32 In / 16 Out
40 In / 8 Out

or even better:

32 in / 32 out
40 in / 24 out
48 in / 16 out
...

Thank you, Mr Miller!

Just a wonder. How are people finding these now? I'm looking into two 16As for my new space now (partner and I getting one each!), replacing a BLA002 and Rosetta. I have no chance to test them out as was my original plan, but I'm terrified to just upgrade to something new, as I should be.

Anything you can share that was recorded, pics of it working, horror/non horror stories would be awesome.

Thanks guys!!

There's no low end rolloff on any of the outputs.

Our priority right now is getting the increased channel counts going. We can look into related ideas like asymmetric I/O counts once that's all squared away. I'm not sure it's technically possible but it's a good idea worth examining further.

MrMiller - Another user posted this on another board as a response from Motu. I know my Earthworks M50 microphone has a published spec of 5-50000Hz but I don't see any mention of that spec on the Motu website. Can you let us know the exact specs for frequency output? Thank you.

David,

Thank you for your interest.

MOTU tests and measures to 20 hz as the lowest frequency for our interfaces. Below 20 hz there is a filter. I don’t have an exact measurement for you, but it’s a fairly sharp roll-off. You’ll get some signal at 10 hz, but it will be attenuated.

If I can be of further service, please let me know.

Dave is talking about the inputs, not the outputs. There is some slight rolloff on the inputs. The outputs have no rolloff on the low end, however. The upper range in both cases is determined by the sample rate. To capture and output the full frequency range of that mic up to 50khz, you'd need to run at a sample rate greater than 100khz, e.g. 192khz.

emrr posted some measurements and response graphs way back on page 12 if you want more detail: https://www.gearslutz.com/board/10346461-post344.html.

I had a little trouble setting up the outputs on my second 16A, but the MOTU tech support is great and I had it going within a day or so.

I haven't recorded anything formally w/it them yet, been mixing through them a lot. Here's a new song from band practice I recorded (@ 88.2) the other night (the violin is D.I. off the amp and sounds like sheet):



They're not too exciting to look at, but I can post pics if you want.

They definitely haven't been announced...not even sure if MrMiller has said more than Motu is paying attention to the Thunderbolt situation on the Windows side. But many of us, maybe me mainly, have stated our concerns for the future of Thunderbolt on Windows based on the lack of Thunderbolt products the last few months...but I guess that was just a market shortage due to the switch over to Thunderbolt 2 so very good news indeed. Of course, it would be nice to see more than one Thunderbolt product regularly available for Windows.

Use the IP adress from the unit itself. Its displayed in the menu. Then go to your browser and type the in the IP.

Thanks... I fixed the problem right before I received your reply. What I ended up doing was getting the wife's Macbook Pro. Downloaded the app and new drivers. Used the CAT 5 and USB to update the firmware on the 1248. Once that finished I disconnected it from the Mac and reconnected it to my PC. The App started working.... Your idea sounds easier. Wish I would have gotten it earlier. :-)

I and a few others in my neck of the woods would be over the moon if Windows thunderbolt drivers were to eventuate for these Motu devices.

Here's hoping !! ?

mrMiller congratulations with the new 112D!
This is a great addition to the product-line.

Would there be any latency advantage to run PCIe-MADI from the DAW through a 112D, compared to connecting via USB from the DAW, to AVB connected units? (at 192kHz)
What would the expected latency difference be?

One more plea. Any Torontonians anywhere have one of these I can hear in action? Pulling the trigger on any interface at any amount without hearing it is a poor investment. I just want to know I'm making the best choice.

A Motu device can operate without a computer. However, if you want to hook up a Motu device to a computer, the computer won't know anything about the device if you just plug it in. There needs to be a device driver for the computer to understand how to communicate to the Motu device. This is just the same as with your printer, scanner, mouse, etc; the computer needs to know what the device is capable of and how to tell the device to do X or Y.

In the case of Motu, at least on the Windows side, they have released drivers for USB so when you connect a Motu to a Windows computer, it uses the (previously installed) device drivers to communicate to the computer via USB.

If you were to connect a Motu via Thunderbolt to a Windows machine, the computer wouldn't know how to communicate since Motu hasn't released a Thunderbolt driver for Windows.

On the Macintosh side, Motu has released USB and Thunderbolt drivers. Thunderbolt hardware is more standard on Macs, while Thunderbolt on the PC side is limited and the hardware isn't as consistent. So I can see why Motu, with their limited development resources, has chosen to expend resources using the most common interfaces, in this case USB on the Windows side and USB AND Thunderbolt on the Mac side.

MADI itself is basically zero-latency, so you're essentially comparing the latency of the PCIe card in question and the USB driver. Probably safe to assume PCIe+MADI would be lower latency than USB.
