Correct. FW is the professional standard for serial ports. Some computers use a cheap version of FW which is really a FW piggybacked onto a USB port. If you have a genuine native FW port they are superior to USB. In a desktop computer you can just put in a PCI FW card and enjoy seamless audio performance. They are not flaky at all. Contrary to popular belief, FW is also not about to disappear.

Hi,

Am I right to assume that both the Presonus AudioBox USB and the M-Audio Fast Track Pro are USB1.1 devices, and thus the bandwidth is not enough for simultaneously playback and record?

(For example if I want to play back a recording, and record a new track while listening to it.)

On the other hand, the Presonus Firebox can do this, right?

Thank you:

Csillag

Audio data rates are very low. MIDI data rates are even lower. All versions of USB are plenty fast enough.

The Fast Track Pro's specifications (here: http://www.m-audio.com/products/en_us/FastTrackPro.html - click on "Specifications") say that in 88.2/96 Khz, 24bit mode, the device can do 2-in OR 2-out ports. (While in 44.1/48 Khz, 16bit mode, it can do 4x4 channels.)

The article at ( http://joegiampaoli.blogspot.com/2011/06/m-audio-fast-track-pro-for-debian-linux.html ) also emphasizes this limitation.

Does anybody know whether the Presonus AudioBox has this limitation, too?

Thank you.

I don't know. But ... how many ports/channels do you need?

I hope so because I just got my Behringer Audio Control device. I read all the stuff that came with it.... not much to it. Plugged it in to a USB port ... Turned it on ... It is all lit up ... Hooked my speakers and headphones to the device .... hit a few keys on my DP .... saw Vintage D reacting ... but .... NO SOUND !

Any ideas ?

EDIT: Well, I just had a thought. Am I supposed to connect my LINEOUT jack from my computer into the INPUT stereo connectors on this device ? I was assuming the input was coming automatically through the USB cable. Maybe that is a false assumption.


EDIT: Yep ... That was it !

Ok, now I have sound.

Now, I just have to see about reducing the hum I hear.

Well, that is a deal breaker. This device is introducing a hum that I cannot live with.

Is the answer to that problem going to be a better device ?

Don't connect the line-out of your computer to the behringer. That actually bypasses the behringer's superior DAC. That's the source of the hum as well. When it is correctly configured there will be no hum.

What's happening is that Vintage D is setup to send audio to your onboard DAC instead of the behringer. You need to change this.

First, download the ASIO driver from behringer's web site (not the asio4all driver). Probably you should uninstall your asio4all to avoid confusion.

Then, you need to set Vintage D to use the Behringer ASIO driver for audio output. This is a similar process to what you did before with asio4all. You will also need to go into the asio control panel and select a speed (rapid, super rapid, medium, etc). These speeds are actually controlling the buffer size and consequently the latency.

When it is correctly configured, Vintage D sound will NOT come out of your onboard audio, only the behringer. Other computer sounds will probably continue to use your onboard sound as they did before, though you may need to configure something somewhere in windows to ensure that happens.

Let me know if your problems persist after doing this. Since we have the exact same setup, I'm sure I can help. PM me if I don't respond quickly, since I'm not necessarily following this thread closely.

QV: Ok, Thanks ... I will be a little while before I get this done. I have another unrelated matter I need to deal with.

gv has it right.

EVERY device requires a driver. Your new Behringer device needs one.

Did it not come with a driver CD?

If not, you can use ASIO4All as gv suggests. But that's disappointing. A custom driver, made for a particular sound card will likely give better results.

No, it did not have a driver CD.

I downloaded and installed the 64 bit drivers.

Ok, Now I just have to wait for QV to get things set up properly.

Right now, all I hear is a steady CLICK, CLICK, CLICK from my phones and when I play on the DP nothing comes through.

In the options area of Kontakt ... I have ASIO for Driver. Behringer USB Audio for Device.

ASIO Config button brings up the Behringer USB/ASIO configuration form.

For USB Configuration, I have Device: Behringer USB Audio, Output and Input are checked, Both Channels show 1+2, Sample Rate is 32 kHz, resolution is 16 bit.

For ASIO Configuration, I have ASIO Resolution 32 Bit, System Performance is Rapid, Application Priority is Above Normal.

EDIT: Now, as an added issue, When I press a key on my DP I am not getting a response in the KONTAKT Player. So it appears I have lost my input somehow.

ALSO for your information I did not UNINSTALL the ASIO4ALL driver because I do not know how to do that. If you wish for me to do that I will need some instruction on how to do that.

I have to attend to dinner now, so I will be back in half-hour to an hour.

Yeah, the thing is that I think Kawai registers itself as USB audio, and so does the Behringer. They don't conflict or anything, but it might be that when you installed the Behringer it made Kontakt think it should get MIDI signals from there. I think mine did that and I had to set the MIDI thing back. I think I had to reboot a couple of times too. Lol.

Dmd, give me a call when you can. We'll figure it out and then post the soluion.

Well, just to close out this thread ....

With GVFarn's help I was able to get the Behringer USB Audio Device installed properly and it works great. Thanks to all for any and all suggestions.

BTW a key TIP for installing the Behringer USB Audio Device (UCA202) is to connect the device to the computer via a USB port BEFORE installing the Behringer driver. If you don't, it will not work at all.

THE END
