Master tuning Hauptwerk allows its overall tuning to be raised or lowered so that it can be played with acoustic instruments, or other instruments that cannot easily be re-tuned. For example, the master tuning adjustment makes it possible to integrate Hauptwerk with real organ pipework, the tuning of which will change with temperature, and to adjust Hauptwerk's tuning to match. Functions | Clear master tuning resets Hauptwerk's tuning to standard A-440 tuning (standard concert pitch), which is the default. The Functions | Increment/decrement master tuning by one percent of a semitone options then allow the tuning to be raised or lowered, with a maximum adjustment of 99 percent of a semitone in either direction:
The tuning increment is displayed in the status bar at the bottom of the main window:
The menu functions can be triggered by MIDI, so you could include tuning +/- buttons on a MIDI console if you wished. Note that the tuning menu functions are disabled, and the tuning cannot be adjusted, if the Disable interpolation (use fixed-pitch playback)? option is selected on either of the General settings | General options or Organ settings | General options screens, since interpolation is required in order that Hauptwerk can control the pitch of the pipes. Finally, note that some sample sets are intended only to be heard exactly as they were recorded and have licenses which explicitly disallow any tuning adjustments. For such sample sets the tuning adjustment menu functions are not enabled. |
