I'm not sure but you are not obliged to use the embedded sound card... if it can reassure yourself.
And the only thing that will say if it's ok or not is a real test. So wait a little and we will have feedback on this forum as soon as they will be available.
PS: I'm really not anxious about this :)

"Yes, but in that review they are also using the controller as the primary sound card. sending 2 audio signals down a USB 1.1 to the controller is likley to bottleneck the bandwidth of USB 1.1 and create a lag between the button pressing & VDJ responding. The DAC-2 is only a controller and doesn't need the extra bandwith to send the audio signals."
Considering that USB 1.1 is roughly 12 Mbps and 2.0 is 480 Mbps. And that true ADSL runs at 1.5 Mbps I do not see really how there would be such a dramatic information bottleneck. But then I am just a DJ hobbyist. ;)

My tests with other USB sound cards such as
gigaport AG (8 channels)
EMI 2|6 (6 channels)
Star Logic (4 channels)
All show that the usb sound cards take about 60% of the usb bandwidth (regardless of how many channels are active). That's plenty left over for a few keystrokes!
I have my main man in the UK getting a hold of one of these NEXT week and will report back on his findings

If you look at the size of a track on a cd (lets say a 3.5 min track), it will probably be 65 megabytes or so. So lets do the math.
65MB/3.5min = 18.57MB/min (data read to play a CD for 1min).
18.57MB/min = 0.31MB/sec
0.31MB = .03875Mbits/sec (8 bits in a Byte, remember)
Now we can compare this to USB 1.1's top bus speed of 12Mbits/sec, and we aren't even close to that when playing normal CD-quality, stereo music. In fact, if you could get a USB port to actually sustain a full 12Mbits/sec data transfer rate, you could technically play over 300 CD's at once through a USB port and still listen to them all in real time.
No bottleneck here.

I have to correct myself here...
0.31MB/sec actually is = to about 2.5Mbits / second.
That means you could send out 4 CD-quality signals through a USB 1.1 port at once (or more if you use less quality).

DjWorkit you are right on...No bottleneck here.
NOW -- that has nothing to do with the USB host controller. I have seen USB controllers that use shared interrupts and conflicts with other system devices and this winds up causing problems.
The question I have to Virtual dj support...
Can you scratch on the Hercules DJ Console?
Is there ANY latency with VDJ with the buttons?

I've seen that you can't scratch with the version of VDJ that comes with the controller.
I also heard that the Hercules controller has a .12millisecond latency, which I believe you could get used to quickly.

phew - good thing Hercules labeled the crossfader.... a n00b woulda been stuck....heh...
looks like a cheap piece of junk to me. i'm still just getting used to the whole dj'ing with software concept...much less bringing that thing to a paying dj gig. the dj's i've played with (who are for the most part all still vinyl, tho you see the Pioneer cd-players on more riders these days) would laugh me out of the building. you should see the looks i get just for SUGGESTING that i might use a laptop one of these days (i'm trying to break the idea in slowly...:)

It says USB 2.0 compatible... I thought of it as an extra point they were trying to make to make a better impression (because of course you can hook up a USB 1 device to a USB 2 port). The wording seems to tell you that its not actually USB 2.0 speed.
Nonetheless, we know USB 1.1 is fast enough.

Well it can will NEVER compare to my rig with a real RANE mixer

wireless! i love your setup! what is that "PCDJ" controller you got there? does that work with this software? that is a rig i would take to a job anyday. that is what i would expect a professional digital dj to bring to work. much respect!

What do you all think of my computer systems. I have purchased the hercules to make a third. Didn't really need it but I have to spend spend spend all the time.

Just looking for opinions. Wish I did buy the Rane that virtual bought.

A little bit more on the USB1.1 /USB 2.0 issue. I tried a little bit of an experiment with my JetFlash 2 GB USB 2.0 Memstick, to see first hand how performance would be. I installed VDJ and about a gig and a half of MP3's to the stick and proceeded to run VDJ three plugins with both decks operating with nary a problem. I did this on an inferior machine to my one at home. This one is an 800Mhz PIII, with 384MB RAM, and a Creative AudioPCI. The stick itself is plugged into a USB 1.1 slot.
Plenty of bandwith, no performance issues.

DJ Homeboy, before I upgrade from automix to virtual dj, should I just wait for this controller system or should I upgrade before buying the controller?

yes, That is the DAC-2 (usb). Virtual DJ also supports the Numark DMC-1 (serial) controller but only if you have the upgrade chip http://www.gizmolabs.net
>does that work with this software?
Absolutely, that is why I bought VirtualDJ, because it supported the controller!
