Truth -

When or if is the real question.

Its not a myth.. its a fact.
My work around is to connect to the mixer with cat 5... then open capture with firewire..
This way the lag is next to nothing.
If you connect to the mixer with firewire first... then you will get lag.

Try it and let me know how you get on.

First off, I don't know. Because I haven't tried it (UC 2.0 or even UC 1.8).

But I can add to the story.

I use my FireWire computer to mix all of my shows. I use the waterfall spectrographs extensively during setup, sound check, and show time. I have both a FireWire cable and Cat5 cable connected from my rack PC computer to the RM32 (Cat5 connected to router LAN then on to RM also) but when clicking on my RM32 in the small UC form to bring up the mixer it shows a FireWire symbol there so I assume I am always using a FireWire connection.

The spectrometer (or faders for that matter) for me has no lag using UC 1.5 and corresponding RM Firmware. I have not upgraded since then because there has been nothing added to UC Surface that was any consequence to me, updates were mostly for Daunte, AVB, CS18, cascading, stuff like that that I don't do.

The interesting thing is that I could not do what I'm doing now using UC 1.3 (and corresponding firmware). For me there was a lag and other goofy things going on when I tried to mix on my PC through FireWire. I would move a fader and hear the change through the speakers after a few seconds sometimes. Other times, the faders would just start moving on their own which other forumites said they believed the faders were repeating moves they had done previously (similar to a lag if you think about it). UC Surface was completely unusable on my PC at version 1.3. I had to use the iPad iOS UC Surface 1.3 and everything was fine, but I couldn't use Smaart or the spectrographs.

Once UC Surface 1.5 came out, all those weird issues went away and I have been mixing over FireWire ever since, at least a year or two. My question is, have some of these issues from 1.3 (and earlier) resurfaced? Or is it a newly created lag issue? Because the descriptions do seem similar to me, maybe not exactly the same, but definitely similar. Another similarity is that the issues for me in UC 1.3 did not seem to happen to everyone! But there certainly were folks in the forums that had the same issues as me with it. Funny thing was, I don't believe there was any mention of it being fixed in the 1.5 release notes, it was simply a wonderful surprise that it all of a sudden worked! (This is why I haven't changed anything since)

Anyone else sense a little Deja Vu?

Indeed it is a fact. I updated from UC 1.8 to 2.01 almost directly after release and I have had problems ever since day one. The lag is really severe, nearly making UC unusable. The past weekend we had two gigs, Friday and Saturday night in two different locations. On Friday night during sound check UC started to freeze and hang, had to pull up Windows task manager to kill it. It kept on freezing as soon as I started UC. I gave up and only run Capture on the main computer and did the sound check with the I-PAD instead. (no front of house tech, doing that on my own while playing).

On Saturday, same thing UC just freeze up and nothing work, this time I had the time to connect to presonus web site and download UC 1.8. Removed UC 2.01 and installed UC 1.8 instead, now everything worked as clockwork again. No glitch, no lag, no freezing what so ever.

So to conclude I am sticking with UC 1.8 until the Firewire issue has been resolved.

I'm having huge problèmes with FW. With just à FW connection, studio one and Capture work fine but UC surface with latest firmware and uc 2.x.x just will not recognise the mixer. No uc surface no wifi. Uc surface no Smaart. Ticket open on and off for months. They can't reproduce the problem. So I start over. Format a new sierra partition, don't connect to Apple. Don't time machine restore. Just add s1, Capture and uc surface. Exactly the same promlem,

Anyone else having this and or lag ? Cheers
Btw mixer is Rm32-ai

I am seeing similar, but due to the Win 10 Creators update. Wouldn't apply in your case though.

Yes, same here, since I upgraded to UC Surface 2.x. This is no myth, this is truth.
UC over firewire can't be used. And connection with ethernet does not support capture recordings. Yesterday I were not even able to run ethernet and firewire in parallel.

Presonus, please help. It is urgent !!!!

I almost can't believe, that this should not be reproduceable there. Let us know, if we can contribute in any way, getting this issue fixed, or at least reproduceable. It is really bad. Right now, I just need the system for rehearsals, but later this year we have a theatre production again and I would need a stable solution until then.

I am not sure where the impression that this issue has not been acknowledged came from. If you read the release notes for UC 2.0.2 (located in your my.presonus account in downloads section, release notes tab), it is listed there under known issues. It has been recognized. As far as when the expected fix will arrive, I will try and get an answer.

There is no doubt that PreSonus has acknowledged the problem. It is mentioned in the release notes since day 1 of UC Surface 2 and up to now in all its 3 versions:

Universal Control 2.0.2 Milestone Release Notes (April 27, 2017)
Universal Control 2.0.1 Milestone Release Notes (March 28, 2017)
Universal Control 2.0 Release Notes (February 21, 2017)

The AI users are waiting for a fix since 3 months now and the only advice can be to use UC Surface 1.8.0 instead, but I am not sure any more that we are talking about 1 problem only. There seems to be a variety of connected problems - like the slow metering in the big meter display in Capture since a longer time already. This thread has the purpose to see more clearly what the problems are, because only concrete observations can help the software experts in Hamburg find a solution (the quote in my first post is from them). UC Surface 2.0 is great, but if it doesn't work with FireWire, nobody can not recommend "using the latest firmware and software" as a problem solver any longer.

I remember more people having this problem or problems, but they haven't contributed to this thread. So it will take more time to get the picture clearer. Meanwhile I enjoy UC Surface 2.0.1 on iPad and work with UC Surface 1.8.0 on my computer...

Hi,thanks for the feedback. If you haven't got one already please open a trouble ticket.

I'll refer to your posts in the latest update to my trouble ticket with Adam.

Together we"ll get this fixed.
Thanks

Meanwhile I enjoy UC Surface 2.0.1 on iPad and work with UC Surface 1.8.0 on my computer...

At the same time ?

Yes. They work with the same firmware versions, so they are not competing. I use the iPad more for visual control and on stage as monitor mixer.

Hi Thanks for the info.

I'm going to clean my UC surface 2.xx installation reboot and reinstall 1.8.0 and se where this leads me.
I'll let you know.
Cheers

Hi, I've tried to load uc 1.80 but it's no longer on the download site so I tried uc 1.81 and that doesn't work.

All the previous non uc 2 versions have useless release numbers so I can't workout 1.80. Could you please advise ?

Thanks

It's still there and it should also be available in your PreSonus account. We are talking about the RM32AI, not the SL 1642, or? Universal Control v1.7.4 is here: http://www.presonus.com/support/downloads/StudioLive-16.4.2.

Hi I need uc 1.80 for the RM32ai. It's no linger available on my download page. Only versions of UC 2 are available

I cant even put an image of the screen in this outdated forum!

sorry

Btw 1.74 is for legacy and the 16.0.2

Correct, in our PreSonus accounts available are only the firmware versions (all) and the latest RELEASE NOTES of UC Surface. The downloads of UC Surface can be found on any relevant present product, so the link is correct. But you need to scroll down, to find the older versions... At the bottom of the page it starts with Universal Control AI v1.5.0.29399 - Mac.

UC 1.7.4 (May 11, 2016) is for all legacy boards: SL 24.4.2, SL 16.4.2 and SL 16.0.2.
