I received an e-mail from Emilie at Arturia this morning asking for photos of my issue so they could help me resolve. I am very pleased with this recognition from Arturia. As I said in my e-mail to Emilie, life is never perfect and for me it shows the sign of a good company that they want to put their teething problems right as quickly as possible for us. I'm really loving my Spark aside from these button issues, which I get a sense that Arturia will sort out for us. Also the turnaround time on this hardware issue has been pretty fast all things concerned - it has only been shipping for 8 days.
It is no big issue for me that they have had this fairly minor problem, many companies have bumps in the road along the way, so long as Arturia recognise it and help me fix it, which it seems they are willing to do, then they have not gone down in my estimations.
Good work Emilie.
