I thought it was a USB issue, and still might be, but fixed itself with a new video card. I was pulling my hair out thinking it was a buffer setting, specific DAW, hard drive etc.. If you are running Nvida, try switching to ATI or Intel. It fixed my QU24.. might fix your 32

Hey
I have a QU24.. was doing the same thing.. Here’s what I wrote to tech support… Video Card issue. After about 5 mins, I would get artifacts and the sound was tinny and crap. This may not be your issue but it took me a while to figure it out.

Hi,
Since nobody has really gotten back to me on this.. I’ll update you with my findings. I did manage to fix my problem, and I’m sure I’m not the only one that it was happening to.
My video card was the issue. Not only my original video card but my replacement video card was as well. The issue was they were both Nvidia based graphics cards. For some reason, your asio driver, or the usb, or something else, has an issue with Nvidia cards.
I replaced the card with an ATI/amd based card and instantly the issue went away. Not sure why but Nvidia cards and your QU24 don’t mix.
I noticed because when playing youtube videos or anything else, the sound would go to digital artifacts, and the video would seriously start to stutter. I replaced the video card but (without thinking) with another Nvidia card. It was still happening and I lived with it for a while, but then it started doing it all the time. I replaced the card with ATI and I can run at 7ms buffer with no issues whatsoever.

I’m running a Gigabyte GA-970-U3 motherboard with AMD FX 6400 processor.

Hope this helps someone.

I’ve never heard of better results recording to an external drive but I will try this. I have 2 internal drives, one for OS and DAW and the other for project files. I’m not sure about my board and I’m thinking of returning it (not sure if I can even). I just rebuilt my PC with non SSD and it is still happening. I thought that the sky was blue again but it is not. Tech support has not really given me a whole lot to work with. The shipping alone (since there is no AH shop close) will cost me about 120$ CAD to ship one way. Great. And I’m not convinced that the issue will be fixed. The board might only be shipped one way unless they or somebody has any solution other than, change the length of the usb cable and adjust the ASIO settings. If I set my buffer size to anything less than 1024 samples it craps out. It should not be this hard.

Yo. This is exactly the issue that I have been facing. I’m not sure if it is an A&H sub par ASIO driver or computer related. I would start with the computer. I believe that my issue (still ongoing) was a combination of my Samsung 840 EVO SSD and the AMD chipset on my motherboard. For some reason with that combination, the drive functioned fast, windows was super speedy, everything was great but I was at the end of the rope so I decided to take a look at it. I tried updating the firmware on the EVO drive and it kept crashing. A couple of google threads later I decided to wipe my drive and start fresh with a generic 7200 rpm HDD. Things have improved DRAMATICALLY. I use Samplitude Pro X2 and sometimes it will complain of dropped ASIO buffers but I have yet to encounter the buffer overrun that you and I experienced.

What are the specs of the computer you are recording with ie. specific hardware? What is the length of the USB cable? If you are using the Qdrive then all is lost 🙂

Also.. check out a program called latencymon… it will tell you which drivers are peaking the buffers. but I found that the application actually created latency when running..

[philt80Participant]

Hey Andreas,
Ya. Both Studio One and Samplitude will alert if the sampling rate for a project is out of spec for the board. I’ve made sure it is always set to 48k though.
Also this has to be a drive/asio issue as non of the other boards I have at home right now crap out like the QU24. (x32 and presonus (firewire though))
I’ve had the projects both on 7200rpm drives and SSDs. I’ve taken the same projects from computer to computer with the same effect. I’ve also had it overrun when there aren’t even any tracks in the project.
Not a clue!

[philt80Participant]

I’ve got the same issue. QU24 as well. I’ve been chatting with tech support with no resolve. I believe it is a latency issue. I’m ready to return the board as this seems to be ongoing and non fixable. I use Studio One v3 and also Samplitude Pro x2. Both after about 5-10 mins produce a buffer underrun and the audio slowly gets to a point where I have to reboot, turn off the board and start over. I’ve rebuilt my pc, all the drivers are up to date. I’m an IT sysadmin so I have a little knowhow but nothing I’m trying works. Ive tried Win7, 8.1 and 10. I’ve tried on laptops, and desktops with enough horsepower to run anything.
The best I can tell you is try downloading latencymon and seeing what it says. at least it will tell you what drivers are giving you the issue potentially. I’ve also tried the asio4all drivers and latencymon reports WAY less clips.
This happens with no plugs, loads of plugs, one track, 24 tracks etc. I’ve adjusted the buffer settings till I’m blue etc. Nothing seems to work for me.

Basically tech support has told me to adjust the latency in the driver to find a good balance. useless. nothing has worked. It has been ongoing for months. I’m pretty disappointed with A&H about this…their reputation was much better than this.
I’ve attached a clip recorded on my phone through my monitors to send to support, also sent a video.
Does yours sound like this?

Thanks all!

I think I am going to try running each set through the stereo mix outputs. That way I can bus my tracks within my daw and control what is going through them (click etc). I can’t seem to find anything but signal flow schematics but I think from those I think I can get my setup correct. I’d like to get everything routing correctly within the QU and not rely on external monitor controlers. I totally understand how the pafl works on the QU now so thats great.

Thanks for all your help all!

[philt80Participant]

dhak.. thanks for the replies.. I’ll check the manual and check out those stereo mixes to route to. [XAP]Bob, suck a lemon and your useless one liner comments.

[philt80Participant]

Dhak thanks for the response and time.
So this is my setup… maybe someone can give me a solution to set this up proper since I’m relatively new.
I have 2 different monitor sets. One 4 inch and one 6 inch set (small room). I also have a headphone amp with 4 separately adjusted volume knobs. I would like to be able to able to select which output I want (either 3 sources) and be able to turn the others off.

Should I be using the mix outputs for these? I haven’t really had a good chance to fumble through the board yet (just got it) but I’m not sure where to start.
I think in my daw I could have 3 busses running to 3 different sends (one I would like click for overdubbing on – to headphones).

Thanks for all your help!

[philt80Participant]

Dave, thanks for the reply. this was my original question.. you said “if LR is routed to headphones”.. Can you route something else to headphones? Say have out 25+26 routed to headphones? I can’t see anywhere to change the routing on the headphones.

[philt80Participant]

Hmmm… not sure if I explained it right. So I have my monitors on the LR main out. When I record drums, I put my headphones into the headphone out… but when doing this I can’t play the tracks because as soon as I turn down the monitors so they aren’t picked up, my headphones also turn off. Maybe I’m not thinking about this right…What I would like is an output on the daw with click enabled and the LR output on the daw going to my monitors.. should I be going through mix outputs for everything and avoiding the mains?

Thanks!

[philt80Participant]

Nope.. I’ve been searching everywhere…

I’ve been posting this everywhere.. I’m using Studio one by presonus which I’m just about ready to give up on….

I need some help with device control on my new QU24 by allen and heath. I’ve set up a new keyboard external device and so far (the easy part) I’ve got my faders moving. I’m looking to get things like pan, gates, eq, mutes etc working controlled via MIDI. On learn mode when I move the pan knob I get this in the XML file….
-<Control title=”Control25″ options=”receive public” type=”knob” name=”controlb0063″>
<MidiMessage address=”#63″ channel=”0″ status=”#B0″/>
</Control>
-<Control title=”Control26″ options=”receive public” type=”knob” name=”controlb0062″>
<MidiMessage address=”#62″ channel=”0″ status=”#B0″/>
</Control>
-<Control title=”Control27″ options=”receive public” type=”knob” name=”controlb0006″>
<MidiMessage address=”#6″ channel=”0″ status=”#B0″/>
</Control>
-<Control title=”Control28″ options=”receive public” type=”knob” name=”controlb0026″>
<MidiMessage address=”#26″ channel=”0″ status=”#B0″/>

THIS makes since considering A&H midi protocol documents say this…
(NRPN MSB) (NRPN LSB) (Data MSB) (Data LSB)
BN, 63, CH, BN, 62, ID, BN, 06, VA BN, 26, VX

Pan
(NRPN MSB) BN, 63, CH, (NRPN LSB) BN, 62, 16, (Data MSB) BN, 06, VA (Data LSB) BN, 26, VX
Where VA Full Left = 00 to Centre = 25 to Full Right = 4A
VX 04 , 05, 06, 07 = Mix 5-6, 7-8, 9-10, LR
VX 0C, 0D = MTX1-2, 3-4 (not Qu-16)

In fact any knob other than the faders I use seem to use these 4 variables.. just different numbers..I can’t find any documentation on this and no support is coming from the forums..

Can anyone give some hints as to how I can rewrite the xml file to only read the pan knob and not all 4 variables? I’m no programmer! Hopefully I can compile an xml file that can be distributed for other A&H QU users..

— Nobody has a clue that I can find..
