Today I have compared Spark to Tremor, another rhythm beast. Spark uses 20% of CPU without making a sound. 25-30% when playing. Tremor 0-1% without making a sound and 15-18% playing. Arturia some process is eating CPU on idle and this is not up to the standards of a company of its reputation. It seems Kevin is the only one who cares. this is not a toy, it's a pro audio vst /controller which eats CPU on idle like a bad written synthesis plugin. Do you think this is fair for Arturia's customers?
Apart for that this controller doesn't work very well with some DAWs like FL Studio. And there is 0 interest in making it to work with it. FL Studio supports many controllers from Kork, Akai, Novation, etc, but no one from Arturia.
So basically I have a great looking and sturdy controller which tons of sounds and possibilities which is let down by its hunger for CPU even when is not in use and which doesn't transmits midi data to my host. Now get your own conclusions of what are my feelings for Arturia (Kevin aside).
