I bought the Audio Evolution DAW, primarily because the developers: a) have developed their own hardware-level I/O driver and b) the devs own PreSonus AudioBox 22VSL and 1818VSL i/fs and have validated the 44VSL (which I own and am replacing with a Tascam US16x8 for SONAR).
The Audio Evolution driver requires a Class-Compliant interface, so no device driver required.
My new Tascam i/f will be here tomorrow, so it may be sometime Thursday or Friday (June 11-12) before I can test the AE DAW and audio driver with my 44VSL and my Nexus 10 tablet.
One other thing...AE's in-app purchases.
In many cases, an app will be useless to barely usable without a bunch of in-app purchases. I think the AE devs have done a really good job of segmenting the cost of the app. The DAW itself is US$6.99. The custom audio driver is US$6.71. If you have a MIDI keyboard that you want to connect and play as a virtual instrument, that'll cost you another $7. Then you can add soundsets.
I have a MIDI keyboard, but it's not leaving my home studio, so I have no need for a mobile interface to it. $6.71 I don't need to spend, but would have had to if the app was just full-priced, all extensions installed and enabled. So, for me, the segmented pricing worked.
Go to the Google Play Store and search on the Audio Evolution Mobile DAW. Look for that developer's app called "USB Audio Recorder PRO". Select "Read More" and then follow the link for tested devices and more info. There are a couple of tables near the bottom that list working and non-working tablets. There are Acers in both lists. The ones listed as non-working don't support USB Host Mode. There is also some discussion about the required USB OTG cable.
May give you some insight into why n-Track isn't working (yet?) on your tablet.
