Hello Pat,
Just as a test, for the relevant organ, on the "Organ settings | Organ preferences | Audio engine" screen tab, try setting:
- "Audio engine processing quality" = 'Medium', and:
- "Tremulant/wind supply/swell box/relay model quality" = 'Medium'.
Those two values are equivalent to v6 's highest quality, so performance should be the same as v6 if you set them that way. (The new-for-v7 'Higher' settings are more CPU intensive.) Changing those settings doesn't require any caches to be regenerated.
Does that eliminate the audio glitches? If so, you could then try setting:
- "Audio engine processing quality" = 'Higher', and:
- (Keep "Tremulant/wind supply/swell box/relay model quality" = 'Medium'), and:
- Select 48 kHz on the "General settings | Audio device ..." screen.
... and if you then still have audio glitches again then try reducing the polyphony limit setting, so as to avoid overloading the CPU.
