1966 Casavant Frères, Exemplum Organum
https://www.hauptwerk.com/instruments/e ... nt-fr-res/
With this pipe organ almost all registers sound weaker than the original wave files except with Trumpete Heroique 8 CH. You will immediately notice this fact because the sound is amplified greatly.
I have documented this fact through the Hauptwerk audio recorder (mono, 32bit) and with middle C sound (MIDI 60) with a duration of about 5 seconds. The following are the comparisons between the recorded mono single sound and the original stereo sound:
GT-Principal8 (p8)
CH-KrumHorn8 (k8)
CH-TrumpeteHeroique8 (th8)
.
Hauptwerk was used with Volume=100 and Trim_dB=0.

If you load/route a stereo pipe in mono then Hauptwerk picks the loudest of its sample's two channels and plays just that one (to avoid phase cancellation through mixing the channels together), with its amplitude adjusted to match the average amplitude of the original two stereo channels.
