...the headers says it all:
we re-programmed the HALION version of the PMI Bosendorfer 290 grand piano library .
The new patches have full 16 layers in seperate groups (folders) which offers more detailed control over the dynamic response and polyphony load for each group.
Also some minor bugs regarding the release samples were fixed.
The new patches are available for both the WET and DRY microphone positions as a free download here: HAL B290 update
