Just curious. What hardware are you running in this machine that doubles time?


If you mean "sound card" it's a Tascam FW-1884 fire wire console. The puter is Athlon XP Barton core running on a gigabyte MB--home brew. Umm... is that what you were asking?

Sorry about the lower case "g", Gigabyte is a brand of MB.

Edit:

And it happened again this AM after trying to run the windows media player when the FW-1884 was not yet powered up. Again shutting every thing down and repowering and rebooting it's AOK. But I'll try that again later to see if I can establish causal link here.

during my years "on the other side of the pond" I noticed the love for acronyms Americans have.

That's very strange, bachus. Maybe try http://www.tascamforums.com. Although it's not necessarily the soundcard. Any particular stimulus that makes it do this weird thing?


'MB' is motherboard.

It's true about the acronyms. Someone should write a sci-fi story written in acronym-speak.

As it turns out no, not as far as I can tell.

check the prefs of the thing and your system and make sure the sample rates match

Hmm.. but that would not affect the computer and the main clock would it?

True, but all bets are off now. Starting over, clean slate, I'll check anything and start a log noting conditions that seem relevant, or that I might otherwise misapprehend as possible casual conditions. But let me stress it is intermittent and not presently rearing its ugly little head.

Another clue!

This am about half an hour apart I imported two little *.mid pieces into Sonar, recorded audio from them and exported them in mp3 format.

Later when I when I auditioned them the first was double time the second was a'tempo. This afternoon restarting the system the first was at tempo and the second was in half time. Then while I was playing the first I booted another computer on the network and while it was booting the piece jumped into double time. All sample rates seem correct.

electro80 did you recieve those files? And if so could you let me know how they sound relative to one another--fast/slow, and Howard?

thanks,

Thanks, I hope that means you like them. Very Happy
But on the downside that is even more confusing. I just now played one and then the other of those files and NOW the first, the up tempo one, was correct the other was playing at half speed, sounds like a dirge rather than like being on gentle waters, yes the very same, the very very same files I sent you and howard.

Does yours sound dirge or waters??


I keep hoping it will just go away.

thanks

On my FW audio interface, there is a setting to pick the clock source. I picked internal, as I want the interface to be the source for everything. Set your buffer lengths in your interface to be as short as you can, then back them up one notch for safety.

In Sonar, make sure everything matches the settings in your interface, and turn off the read and write buffers. Check under options/audio that the record and playback timing are set to appropriate ports on your Tascam interface, and change them to see if that helps. Of course make sure the bit depth and sample rates match. Try changing your driver mode. WDM is probably the safest. Change your synchronization settings and see if that helps. Rerun the device profiler (duh).

Personally, I run everything at 44.1 KHz. I see no value in running things at higer bit rates only to down sample later in the chain. I've talked to a few professional recording engineers who do this because downsampling later can generate undesirable artifacts. But this bit is OT.

Thank you, and thank you. It feels truly good to hear that some one is getting pleasure from something I created. Embarassed Very Happy (I couldn't find the "embarrassed by praise" emoticon)

I can't do that, had to use a SPDIF mixer for the source--no real problem I wouldn't think...but....

the "record and playback timing" were not set to the SPIDIF channels so I'm trying that.

I have to set my buffers in Sonar to 3 but I can't remember why--there was a reason--may have been required by the Tascam FW-1884---zat a big problem?

Yup, yup, and yup.

Will do that after seeing how specifying the right clock works out.

I do that but because it was simplest, nice to know it's justified.

Many, many thanks Howard, I haven't enough hair left to pull out in times like these. Very Happy

Some people will argue about the 44.1 KHz rate, but then they say, "hey, listen to my music" and provide a 192 Kbs mp3 file. Go figure... Anyway, I hope this works out and you get your problem solved.

As for timing off of the SPDIF mixer, is that your TASCAM or some other device?

The Tascam has a single SPDIF I/O. I have several synths that have crumby analog audio so I have to use the SPDIF on them, so I bought a Roland M-1000 for those synths because these synths also do not have WordClock in or out and the Roalnd can deal with it and D'OH I just realized it has WC IO so I can sync it from the Tascam. D'OH big time. HoKay next time I go into a town that has a Radio SHack I'll get a coax cable and do this right.

Thanks again Howard.

.. you are having problems with the master clock? Is that it?

At this point I don't really know. Was completely clueless until Howard gave me some.

So you have both a the Tascam hooked up via FW and the Roland M-1000. Somehow you have to use one as a master clock. How do you have them hooked up?
