Thanks for encouraging :slight_smile: The reason i was worrying - is the first experience with A4 unit, when it had some mechanically wobbly rotary faders and the overall feeling of the refurbished product (rumpled manual and etc). So the first experience wasn’t positive :slight_smile: I have exchanged it. Now i’ve got totally a perfect unit, even the sound differs :slight_smile: no doubt. When all the people around different forums complained on relatively low volume of the A4, mine (the returned one) was the opposite, and now i’ve figured out comparing of the received one - with a bit distorted sound (not the issue of the input gain on USB sound adapter). So, now the sound is totally pleasant, no distortions, and i cannot really stop to believe it haven’t got any issues :irony: that’s because i’m continuing to find ones :joy: Superb synth! :wink:
