I'm very curious about the audio improvements of Hauptwerk version VI (which we've read about in some places - I'm still using version V myself) and would find it very interesting if someone could record the same piece with and without the two new audio improvement options for comparison. Maybe others who are considering an update would find this interesting, too? Or does such a comparison already exist on contrebombarde that I have missed?
I have a set of four example (WAV) recordings of the same piece (one was made with Hauptwerk 5 and three are made with Hauptwerk 6 using different settings), which I am willing to share. (If so, please message me an email address.)
I group these recordings "blind" and out of order, and a key to what each one is can be provided afterwards.
(I do have my own position on this subject, which is that the differences are not audible in realistic cases and that people are just convincing themselves with confirmation bias.)
Ever since starting HW 3.11 I've heard crackles and pops now and then. They diminished as I implemented various upgrades to hardware, and as the HW software releases improved the system. I still had a glitch now and then with HW5, but since upgrading to HW6 I haven't heard any. The upper frequency stops especially mixtures and mutations have always sounded a little distorted to me, they seem more realistic in HW6 but that's the only improvement I've noticed. I'm running all my sample sets at 96Khz.
