Odd MIDI problem with Cubase SX3 & Scope Luna

[CreamWare4Ever]

Hi,

I'm using Scope LunaII card with Cubase SX3. I have problem with timing of recorded midi tracks.

Cubase somehow moves back all recorded midi notes so during playback they play a slice earlier then recorded! In edit i can see that all of them began earlier than I have played.

I have done test with synchronising quantized M1 sequencer notes to Cubese SX3 – it is the same.

Beside this problem, I'm playing virtual instruments with 1ms latency without problem in Cubase SX.

Any idea on what could be wrong?

[garyb]

have you tried checking "use system timestamp" in the device setup?

[H-Rave]

go into asio mutimedia setup and run a buffer sync simulation,you might find they're out of sync.
good luck

Hi,

The problem is that when I open ASIO Dxfdsetup.exe and Wpsetup.exe in Steinberg folder, I can't run a buffer sync simulation. I'm getting following errors:

“Not all the selected devices in the current configuration were successfully started with their selected options. If this card (...)”

When I click on 'Check Buffers and Sync' I'm getting following:

“Errorcode: FF8-5-000C
Info: Device could not be opened”

Same thing when I click on 'Detect Buffer Size'.

Any idea how to solve this. That is the first problem.

I'm using ASIO Multimedia Setup v. 1.7.0.8

When I use Scopes card midi ports without straight WITHOUT 'use system timestamp' unchecked, the midi notes records a bit late with appr. 5-7. So instead of 0.0.0.0 it is recorded at 0.0.0.5.

When I use Scopes card midi ports without straight WITH 'use system timestamp' unchecked, the midi notes records a bit late with appr. 5-7. So instead of 0.0.0.0 it is recorded at 0.0.0.5.

Is it better to use Mdi devices as Emulated maybe?

I will appreciate any help.

H-Rave,

Yes you have a point there. The question is: How check if everything is OK with them? I mean how can I do some sync test and so on? Are there some tolls that I can use?

[garyb]

there must be wave drivers present to run the asiomultimedia test......

[CreamWare4Ever]

Hi again,

Wave drivers are present, but I'm still getting that error. Maybe I shall use another tools? Please assist.

[garyb]

you are putting a wav source and dest before openig cubase to do the test?

you have rebooted?

possibly messing with(disabling) dx acceleration(in dxdiag.exe, i believe) would help.

using emulated drivers is also worth trying. usually they are worse, however.

[H-Rave]

In your scope startup project, which asio and wave drivers are going into the mixer ,as the asio driver syncs off the wave driver buffer ?

[CreamWare4Ever]

Garyb:

- Yes now I can do a 'Check buffer and sync' but I can't do 'Run Simulation'. Test returns no problem for C-Media Wave Device.

On 'CreamWare Rec/Play 1' test I'm very often getting one synch lost – at the beginning of test. Error code: FE6-2-0700.

Just be sure: Which devices shall I check / uncheck in Wpsetup.exe and Dxfdsetup.exe for optimal performance?

H-Rave:

I'm not using Wave driver at all, just ASIO source into mixer and ASIO destination on the other side if mixer. When Windows start I have not add any start up project. Shall I do so?

I'm a bit confused now. Everything is working OK with ASIO in Cubase SX3, beside the midi part. Midi notes are recorded 5-7 measure units (25ms?) earlier.

Maybe If I use some external Midi interface (USB?) this problem will be fixed?

I will appreciate your help.

And this one:

[garyb]

i think the wave modules must be connected to the mixer to run the test.

for the dx thing, go to start/run and enter dxdiag. you can experiment with dx acceleration on the audio tab and you can try disabling direct draw acceleration on the display tab(change one thing at a time, first). if this doesn't help, set everything back the way it was.....

[CreamWare4Ever]

I have tested now with dxdiag. It was OK. The only thing that it returns is a warning that 'Sound Card does not support hardware buffering'.

So I don't know what to do next.

Maybe this problem will get lost if I use some external midi interface instead of them on Scope card?

[garyb]

what exactly did you test?
dxdiag is not for testing, it's for controilling the dx setup.
have you tested for midi latency by lowering dx acceleration and/or video acceleration?

possibly you might have better results with another midi interface, but i don't have any of your problems with any of my machines....

[H-Rave]

you need a wave source module connected into your mixer, and a wave dest module linked to the out , put them in(yes that's an order)otherwise the asio WON'T sync.Oh and dxdiag always says that.The wave source and dest are in software io's,don't go for 24 bit wave source.Oh and in your mixer turn them to stereo inputs as opposed to 2 monos panned L and R.And one last thing Dxdiag reads out of the windows registry(Run,Regedit(Look but don't touch))whether or not the hardware is there,it will appear,(I may stand corrected by another user).

[CreamWare4Ever]

- I have done per your instructions but I still can't check the C-Media Wave Device.

- In ASIO Multimedia setup panel, what shall I set as sync reference: 'C-Media Wave Device' or 'CreamWare Play/Rec 1'? Please tell me that.

Is there any tool that can actually check the really midi latency and return result as digits? In Cubase I can see the latency for Audio but not for MIDI.
I have disabled hardware acceleration for graphics. My midi notes are still recorded late or early.

The only thing I can check buffer for is 'CreamWare Play/Rec 1' in Input Ports panel.

I still can't run simulation because of some strange reason.

Any idea what I can check next?


I send over a screen so that you can see how midi are recorded despite the fact that it is done from another sequencer with sync clock from Cubase.

Maybe Cubase is messing around with midi data that comes in???

[garyb]

the asio latency thing you circled is not important to your problem.

the C-Media device is the onboard sound most likely. don't use it for anything related to cubase, it should probably be disabled in the bios(unless you have something you must use it for).

[CreamWare4Ever]

Hi,

Yes I can do that from windows actually, but since I don't use any external midi interface, it is pointless. I assume that on board midi solution shall be OK, but maybe I'm missing the point or something is wrong.

How much midi latency or shifting shall I tolerate? How to measure that?

[hubird]

it shouldn't be a concern, i never bothered about it.
The only thing that should bother is the latency you experience when playing 'life'.
13 ms is what you would expect these days.
Other timing problems shouldn't be related to 'latency', I'd say it's related to priority settings and the like, or even bugs.
I can remember this strange 'timing' problem was reported befor, but not on mac, so I don't know.
It just shouldn't be there, you have to tweak

[CreamWare4Ever]

Well I have 1.5 ms latency for playing live in Cubase and that is OK as you said. I will try one thing with Reason. I will do the same thing and check if it behaves in same manner as Cubase. I will be back
