Tascam us1641 users! Read this

Add this Note Oct 4 2010.
I'm still curious as to what the RTL would be if you install the new drivers V 2.0. Or if you have a 64 bit system. I tried but they failed. I had to revert back to V1.0. I have emailed Tascam support for advice on which drivers I should be using. There answer ( get this) "Use the old drivers if they work for you!"  
There's no problem recording normally in sync. I did a test by plugging output to input and re-record a kick drum and it is perfectly on time.  

I'm wondering if any of you other users have tested the Tascam us 1641 for RTL, and if your figures show better than mine?

So far it's been doing a flawless job of recording our band live. Sonar adjusts to whatever your sound cards bad habits are so I have not noticed any latency while working with it. 
  I tried looking up the specs and could not find info for the us1641's
Jim Roseberry pointed me at a RTL checker from CEntrance its free download here;

Download this and test your RTL and post your results here.

So I ran it and was shocked at the terrible results 

At Normal  128 samples 44.1 I get 28.1 ms
At Low Latency 256 samples 44.1 I get 22.5 ms
At Lowest Latency 128 samples  44.1 I get 15.7  ms

I can't use the lowest setting with this computer. But even if I could that's still to much to use this interface for real time efxs.

Anyone out there????

217 people have looked at this thread but I would still like to hear how other folks are doing with this interface.

Here is my answer from support


John,
 
More than likely you need to update the firmware for the US-1641 to 1.02. The 2.00 driver added Windows 7 32 bit compatibility and correct a few issues. If the version that you are currently are using is working fine then you could always stay with those.


Doesn't answer my question regarding why Version 2.0 crashed Sonar. But good news is the answer came back within an hour.

Thanks Beagle, Ya I'm wondering why the Tascam users are being so quiet?
I don't have the time right now do dig though old posts but I know a few chimed in a while back when someone was about to order the us2000. It does not have MIDI jacks and is 3x the price. You can bet the drivers are also sketchy too.
I just want to know if anyone is using this interface on windows 7 64 bit and what the latency is.
(ps -thanks for the bump too :)

Thanks for the Bump BT21, I see there are a few users and thanks for diging up that other thread. Now at least I know who's being quiet out there.
Like I say there's no problem with recording as Sonar just adjust things to line up. You just won't be able to use it for things like Guitar Rig. For the price it was still a good investment and I have not had problems recording 10 tracks live into an old laptop. But my question still remains, does this unit perform better on the new drivers? Mooch?

Are you using Windows 7 or Vista?
As you see the reason for this thread is I want to know if anyone is successfully using it with the newer drivers. They didn't work for me with XP SP3. The old drivers are working fine.
I have no trouble with windows or Sonar recognizing it.
I even hot swap my M-Audio and the Tascam sometimes and it just changes in the control panel without a hitch, Of course this is without Sonar running. Make sure you activate the Tascam before you open Sonar.

I did totally obliterate my on boards audio drivers. I did a fresh install of windows and didn't install the drivers for the audio ( or internet stuff)  in both my computers.

Thanks Jimmy, That's the answer I've been waiting for, so it does work with W7 64. And yes thats a strange thing regarding the USB ports. I checked both my computers and they were fine. But that might be jkotola's issue.

I have a US 1641.  I'm using Windows 7 64.  I use the 2.01 or 2.02 drivers and 1.02 firmware for the US1641.  The last drivers made a huge difference in stability for me, so I highly recommend them. 

I was curious as well. I think I'll probably be back to run a similar test on my sound card.

Another story -
I normally use the Tascam on my laptop and my M-Audio Fast track pro on my desktop.
I recorded a couple live band projects using the laptop and took them home to do some overdubs and add MIDI.
I copied the files over to my desktop and though it might be a better idea to stick with the Tascam so I hooked it up. No problems at all with guitar and bass audio tracks, but the minute I started working on MIDI ( TTS-1) , pops and crackles, ??
The settings are more or less the same as my M audios 256 ms buffer 48hz - 16 bit.  etc.
I swapped back to the M audio and no problem with MIDI.
So I still believe the drivers ( V 1.0)  for XP are not very good. It works great for audio but so did my Sound Blaster Audigy.

Thanks for taking the time to post results stokedboss,, , I wished a few more would too.
So looks like the results are about the same then with a newer, faster machine running the latest drivers .
One would conclude that RTL is a factor of interface design and not anything to do with your computer specs. But you should be able to run at lower buffer settings on a faster computer one would think? 

 Even though your interface is a completely different model,  We do share one item in common, Crappy drivers-- . I see they still have iffy driver support, The only drivers that show for your interface are  "windows 64 or 32 bit?? No mention of XP, Vista or 7?? That cannot be a good thing as each OS is different I would think.
Oh well. I guess Tascam "used " to make good stuff.
I'm still happy enough with the sound quality. But very bad RTL and I cannot get the MIDI to stop crapping out on my desktop. Works fine for live recording of audio with my laptop so I don't care as that's all I use it for. Next time around looks like RME for me.

And you say your having issues and you haven't dealt with the latency spikes?? Why??
If you don't optimize your computer it is just a office/ gaming computer and will not work as a DAW. I don't care who's interface you try and use. Get those spikes under control. Funny you paid $300 for the US600 with only 6 inputs  when the us1641 is selling for $200 and has 16 inputs.
Is it winter there yet?? it's still bloody winter here! 4C this morning! I'm going back to Hawaii...
