Hi everyone! I bought this keyboard. When playing, I feel a delay, a small one, but it's annoying. It does not matter, what buffer size is set in the audio card settings. Is this a feature of this keyboard? I had Roland RD2000 for about year and I don't remember the same problem, when I used it as a midi keyboard. The question came up, should I return it or is this some sort of temporary bug in the drivers for this keyboard ?
