"Check for current drivers!"

Verified Customer zZounds has verified that this reviewer made a purchase from us.
Sadly the lack of Win7 drivers killed it for me. I submitted my RMA request last night, and now it is approved (thank you zZounds) and will be sending the device back to today (6/24/2010). I'm glad they have such an awesome returns policy! I don't want to bag on this device; it's probably a great value in many situations. For me the main problem was lack of drivers for the current version of Windows; and the whole point of this review is to help others avoid this problem! Before you buy the device, check E-mu's website to see if they have drivers for your operating system.

Sound
It did sound good when I had it working, but see the support section below.

Features
Includes a LOT of software, and a pretty well-made USB cable with braided shielding and an outer clear plastic covering.

Ease of Use
Overall simple to use.

Quality
It's plastic throughout, but seems well-made and solid despite that. The monitor level pot has no white stripe, and no stops - it rotates continuously.

Value
The device is likely a great value for the money *if* drivers are available for your OS.

Manufacturer Support
Long story short: as of June 2010, there are no reliable Win7 drivers for this device. I received the E-mu Tracker USB Pre from zZounds on 6/23/2010. After much tinkering, I decided I could not get it read more to work reliably in my Windows 7 setup - E-mu have yet to release Win7 drivers for the device. I consider drivers to be "support" so this is where I will document the main issue I had with this device. (It should be noted that I was installing this device on a Thinkpad I had JUST rebuilt with a new, stock, legit copy of Windows 7 Ultimate, 32 bit, fully updated. The ONLY other software/driver I had installed was Audacity. So we can rule out operator error, malware, or other device/driver/software conflicts as the source of the problems I outline below.) I had thought that the released Vista drivers would work fine - usually Vista drivers are OK on Win7. In this case that was not true and I can't say technically why. Even when I could get it working somewhat, the best sample rate I could get was 48kHz; a shame since this device is supposed to go all the way to 192kHz. And even at 48kHz I sometimes experienced dropouts, likely due to driver issues. I tried the drivers on the included CD, and when that failed I uninstalled them all and downloaded/installed the latest driver set from the E-mu website. A check around the web revealed I was not alone; many other Win7 users have had similar problems. Given that Win7 released about 11 months ago and E-mu still doesn't even have beta drivers up for this device (or their 0202/0404 products which apparently share the same drivers), I didn't feel it was worth waiting and taking the chance that E-mu might take many more months to release a usable Win7 driver (or never release one at all!).

The Wow Factor
The 192kHz sampling frequency was pretty important to me. I realize that sounds like overkill today but I'm making archival recordings for historical use and so I wanted to prevent the possibility of some future person saying 'if only they had sampled at a higher frequency!' Plus the device had great reviews from others who seemed to have use-cases similar to mine.
