Hi,
Got it! Thanks for your reply and helpful image.
A few additional helpful notes from testing:
1. IRs can be loaded directly into Open Air by dragging from http://www.openairlib.net. All mono, stereo (including binaural and ORTF) and omni impulses can be loaded. True Stereo impulses (4 channel stereo) generate an error message, as do surround impulses.
2. Once downloaded, IRs from http://www.samplicity.com/bricasti-m7-impulse-responses/ can also be loaded into Open Air, either by dragging directly or opening the dialog. The Briscati IR's are organized as M-to-S or as multi L-R mono files. The former will load, as will either mono file. However, attempting to load L and R files together will crash Studiio One.
The M-to-S IRs sound heavily processed, to my ears at least, whereas the L or R mono files sound less complex.
A nice feature of Open Air is that after loading one IR from a folder, the other IRs in that folder become available simply by clicking on the Prev or Next buttons.
Thanks again for your reply. Hope my additions help others looking for similar assistance.
Cheers
