VAU, I don't know why you would even bother buying an Arturia product until they make good on their current responsibilities. I'm not meaning to attack you in any way, I just don't get it.
I've looked through their downloads page under the support section, and I don't see a lot of firmware updating on any of their hardware products. The matrixbrute is a much more complex instrument than most of their other hardware and, due to inexperience (maybe over confidence too) they did not budget enough resources for needed updates to fix bugs and upgrade features as user conect with their product. A huge misstep in my opinion. Now we all have a bad tast in our mouths.
That all being said, they DID promise a big update in the first half of this year. I am hoping that they do come though for the customers who took a chance on them in a market with much competition. I am not a rich person and I paid more than $3000.00CAD with tax for this item. That kind of money goes a long way in a home based studio. If they do not respect me as a customer and support the equipment they sell, I will not allow them to burn me again, plain and simple. Dave smith Instruments, Moog, Korg, Roland and others are in the same competing market. These companies often go beyond expectations to make their instruments expand in ability after they ship. Arturia have allowed simple bugs to linger for almost 2 years.
I refuse to spend one dollar on an Arturia product until they show their customers and their instruments some respect.
