A sync error ocured. press stop and play to clear

[erolz]

Hi,

Just installed a clean Cubase4 with all the latest updates (4.52).
When i load the Virus TI Snow as VST instrument and start playing my song (with or without any sound loaded in the TI) the Virus control software keeps saying "A sync error ocured. press stop and play to clear".
When i press stop and play the (empty or with midi data) song again, it keeps on saying A sync error ocured. press stop and play to clear...
I wont stop.

Heres my setup:
Intel DualCore2 2GB RAM
RME FireFace 400 connected to a TI fw chipset
Virus TI Snow connected to USB
Steinberg Cubase 4.52
Virus TI Installer 2.7.5 for Windows

Anyone here got the same problem?
Thank you.

I've been getting the same issues since having upgraded to 3.0

Basically, I'll load up the VCC on an instrument track and I'll get this error in red, at the bottom of the VCC gui. "A sync error ocured. press stop and play to clear"

I've only noticed it happening when I'm clicking or browsing through patches in the VCC. *edit* (during playback)






My current setup is:
Macbook Pro 2.16 c2d, OSX 10.5.5, 4gigs RAM, 320g 7200rpm Seagate internal, PTLE 8.0, MBox Pro 2 FW

ive just installed a fresh Cubase 4.1 with the Virus TI Installer 2.7.5 (in stead of Cubase 4.52) and now the Virus works fine.. looks like 4.52 is the problem here?

In my case it's not. hehehe
But honestly, until Digidesign releases an update to address the GUI mouse offset with the VCC and a few other plugin's, I'm fine working directly of the TI itself... takes my face away from the computer screen. ;)

I had this and i installed new drivers new virus software blah blah, then i remembered i had set my asio to 50 for a kind of old plugn.that was crackling.

when i set ASIO back to 10 then it stopped happening.

Yeah, same here also. I kept getting this message within Cubase SX3 and my Virus Snow was virtually unusable. It was solved by reducing the ASIO buffer size (latency) on my Steinberg MR816X interface. Do you have your ASIO buffer set very high?

I also have this problem, but this error message aslo make my Virus ti Desktop to crash!

I heard from access that they think it has something to do with soundbanks in the user library in VC.
So I removed all software (including the user library) and did a fresh install of drivers etc. So the banks in the user library are only the ones with come with the update.
Still the same thing...a crashing Virus Ti.

Yesterdaynight a played with several settings in Cubase SX3 and my soundcard (focusrite safffire), like "lower latency on/off", "release Aiso driver in background on/of" "change latency from my soundcard manualy" (the best I can get is 5ms on playback) all with no results

B.t.w. I don't use the virus as soundcard

I have this since OS3.0.X

Hopefully access or somebody else have a solutions for this

Update on my last mail:

I went back to 2.7.5. for testing. I do get the sync error in this version once in a while, but the Virus itself is never crashing.
Back to 3.0.1.12 then and the Virus is crashing again while selecting sounds during play and stop the sequencer after the error massage.

I'm pretty sure that it has nothing to do with my PC or soundcard settings because I did not change them.

Another strange thing: When I select the virus as my soundcard (Virus USB audio driver) I do not get the error massage again, but the Virus still crashes after stopping the sequencer but less frequent then when I select my focusrite soundcard driver

It looks like, I'm alone with this problem after the last update .12
Before there were more.

I don't hope so:-(

sorry huey, but you mix things up here. the error messages doesn't make the virus crash. it is a side effect of the crash that virus control displays this error message.
as for the patch banks, i wanted to see if a possibly corrupted bank would make the virus crash. that's why i was asking you for the sound banks. but as you can see yourself, it wasn't the sound banks.
i can't make my virus crash, as much as i try switching in between sounds. it would be of great help if somebody (who has this problem) could explain how i can replicate the problem.

for those who get sync errors (and nothing is crashing meanwhile): you need to trouble shoot your system. the sync error displays once the data on the USB buss doesn't arrive in time. it means that something delays the USB packages or packages get lost. access support can help you sorting this problem.

best, marc

Thanks Marc for the reply.
I did send you my user library to ms@access-music.de on 22-04-09, but as you can read I do not have a particual bank that make the virus crash. All the soundbanks do, even the ROM-banks.

The virus crashes at the moment I stop the sequencer. There is a loud ieeeeep sound coming out of the virus and sometimes some noizes after that. All the lights on virus will go out or stop blinking. Sometimes It will come to live after 10 sec, but most of the times it's dead and I have to reboot.

I ""hope"" some more people will report here with this problem so access can ty to replicate it.

I will try to install the virus on a different USB port, though it is installed now on a dedicated USB card with nothing else connected to it

Virus TI2 3.09 and Cubase 4.52, Fireface 400, Win XP Prof.

try it with the 3.09 on the ti, this one is working good on my system, still some issues, but never crashes, sync is ok (syncerror only sometimes)

Thanks Marc for the reply.

I did another install on a different USB port on my dedicated USB card and I did a install on a USB port on my motherboard (ASUS P4PE) both do the Virus crash when selecting sounds during play and stop the sequencer:(

When I have some more time I will do a install on my girlfriends PC and look what's happening then.

When I set the "bar offset" under "project setup" in Cubase SX3 to 1 instead of 0 I do NOT get the "A sync error ocured. press stop and play to clear" error anymore!!

My Virus still crashes when selecting sounds during play and stop the sequencer, but 1 problem solved

1 to go

i have the same problem since going to v3
not the crashes but , the sync error and crackles

[drakeblood]

I have same exact issues (crashes, random sound destruction, out of sync) both when switching banks during playback, arming/unarming the channel for recording, and also VirusTI crash during rendering (with a sound destruction of about 2-3 seconds before this).

The host i use is Reaper (3.0) and OS 3.0.2.02beta on a Polar.
I dont use the TI as audio interface but it goes out from a Delta1010 at 5ms.
The Delta is on a dedicated IRQ (if someone wondered) and works like charm even at 2ms, the VirusTI have a dedicated USB port with dedicated IRQ too. During all those issues the CPU was always under 10% use and the crashes appens with standard banks too (my tests was made with 2 banks running, a kick and a bass)

After some troubleshooting and random tweaking i found out some solutions (but they doesnt solve all 100%)
a) disable "anticipative FX processing" will lower the crash chances (in both "buffering" and "audio" settings of reaper)
b) in the "playback" settings, disable all the "seek" options that makes "seek" during playback (this reduces a bit the out of Sync issues)
c) in "audio" settings, disable the "not process muted tracks", this lowers the out of sync when arming/unarming/arming the MIDI track of the VirusTI

doing those steps i lowered my chance of 90% crash and out of sync to a mere 20%... but still it crashes and it goes out of sync kinda often (during rendering it can happen anytime, usually after 20-30 seconds (but can be more))

...of course i do realtime rendering (called "online rendering" here)

any advice?

It's a problem with the Virus OS not your DAW, a number of people (me included) are also having problems with random crashing and all that crap. I was told Access is aware of the problem and are working on a fix when I emailed support earlier this week, so you pretty much just have to live with the crashing for now until an update is out.

[drakeblood]

Marc in few posts stated that he wasnt able to make the Virus crash or to make him go nuts, so here my Reaper project that kinda often leads to a nice crash (in 2 days i juggled with it i got at least 30 crashes).

This save was made exactly after 4 crashes in a row (but it started crashying only after 2 hours i was playing with it... and all what i was doing was playing with modwheel, automation and RealControlMIDI)

download link of the project (Reaper 3.0):
http://www.megaupload.com/?d=3DUWQR0G

VSTs used in this project:
VirusTI (i tested with all the 3.x versions, even with the new 3.0.3 who gave me 4 crashes just now after 2 hours juggling on this project)
ReaComp
ReaControlMIDI
Waves Q3-Parametric
Waves C1 Comp
Waves API 2500
Waves LinEq Lowband
BlueCat Dyamics
Oxford Inflator
Oxford Limiter

but you can even disable them all (except VirusTI and ReaControlMIDI, they are the ones leading to a crash of the VirusTI).
basically stuffs i usually was doing leading to a crash:
- when playing, edit the ReaControlMIDI. Or play just after an edit.
- playing with automations meanwhile playing
- playing a bit with stuffs on the Virus and/or VirusControl (both while playing and while on pause)
- while playing, change selections or make it continue playing from another point (seek) (this, more than a crash, leads to an out of sync)

the problem is that, right now, i'm playing again with those stuffs trying to make him lead to a crash but without success... then maybe after 1-2 hours the crash appears again (and usually then it starts crash 2-4 times in a row)

[tranqui]

I have this issue with ableton 8 and the VC plugin.

I work with multiple channels, but rarely use more than 2 simultaneously because the TI can't handle too much. the error occurs whenever I trigger a program change on any channel (either the one holding the VST or one of the the ExtInst channels), regardless of whether this happens by pushing a button on the unit or launching a MIDI clip with a program change.

the funny thing is that the virus actually doesn't crash, produce audible artifacts or go out of sync; it just shows the message. I've left it running once for 2 hours to see, and it also worked flawlessly in live situations. still, I'd prefer not to see this error message at all...

// edit: FYI, I don't use the virus as an audio interface - I use a fireface400
