I chose this card because of its price is very attractive to 4 outputs and also manages the South.
It lacks an on / off button but it's a detail.
Manufacturing is serious and superb finish.
I use it with a guitar input and the Cakewalk Music Creator software (44 € chez Thomann) to give me the backing-tracks that I load from the site of Goran.
My config is an old PC with a Pentium IV 2.4 Ghz

UTILIZATION

The installation went without any problems and simplicity unmatched.
The manual is a little too short but it comes out without problems.

GETTING STARTED

I have not encountered any problems.
There are many switches and pots on the box and this causes many trial and error before finding the right setting.
I do not use more than 16 tracks so I have no problems

OVERALL OPINION

I've had too little time to give you a definitive opinion.
What I like least is the lack of on / off button but it's a detail.
For the price (164 € chez Thomann) I have not found better. I hesitated with Guitar Rig Mobil that seemed better in modeling but I do not regret my choice.
Without hesitation I would do this choice because for the price I have an interface with 2 inputs and 4 outputs, management of the south of amp models and effects.
There is no digital output but to have it more expensive.
The Novation Nio 2 / 4 is the best choice.
