Well it is not a ugly sound or anything like that, just not used to it and i was surprised and afraid something was wrong! The world of analog is new to me, and it is great to know that this is not unusual analog behavor. I love the sound of the thing so far. Thanks for fast answer! Further explanations would be nice though, since the sound does not always appear, only on different settings, but there is no pattern, when i am playing a melody , it just comes randomly, mostly when i am not holding notes long. Some explanation from Arturia member would be fantastic!
