Hello Lukas,
There's actually no need to use v6 itself for comparisons -- the two settings on the '
Organ settings | Organ preferences | Audio engine' screen tab will give exactly v6 quality if you set them as follows:
- '
Audio engine processing quality' = 'medium' (=v6 quality with the 'high definition pitch-shifting option on), or 'lower' (=v5 quality, or =v6 quality without the 'high definition pitch-shifting option), and:
- '
Tremulant/wind supply/swell box/relay model quality' = 'medium'.
To hear the audio quality of benefits of v7 above you need to set at least the first of those two preferences to 'higher'. Try setting both to 'higher' with St. Anne's, for example (and ideally also using 96 kHz for audio output), then compare with them both set to 'medium'. The differences are likely to be most obvious when the wind supply model is prominent, and/or when tremulants are active -- anything that causes the sound of pipes to vary dynamically. Here's a note from the v7 release notice about that:
The sonic benefits of the ‘higher’ modes for the two preferences may be particularly easy to hear on modeled tremulants (especially modeled deep tremulants, as found on some theatre organ sample sets) and on organs with very dynamic wind supplies.
Best regards, Martin.
