UTILIZATION

I just want to clarify that before buying this product, it is essential to verify that none of the components of your computer is incompatible (for example, in most cases, the chipset of the motherboard). Visit the Digidesign website to see the huge list of incompatible hardware. it will only be after this huge check I advise you to buy the product. because I did not check and I had to change my motherboard (which by the way, this works much better than the previous one then it is not necessarily a bad thing, but instantly it's bitching !)

GETTING STARTED

Since I changed my motherboard (and a dedicated disk partition and an operating system to Pro Tools), it works wonderfully, I am totally satisfied. the quality / price ratio is perfect.

OVERALL OPINION

Very happy ...
