. 48 kHz own projects with legacy compatibility (r-68 for example). . 96 kHz own projects for HD compatibility. . 44.1 kHz extra version for audio for music for digital release (Amazon, iTunes, etc) also digital store will encode to AAC/MP3.
Remember that in Europe from 2013 BWAV 24/96 should be the standard and FLAC the distribution standard.
Mostly 96khz, only switch to 44.1khz when I'm sort of required to (when mixing with source material that's only 44.1 for example, I don't go to work with it at 96, or when using a plugin that only works at 44.1, or in the extreme case when CPU power is limited, like recording at location on laptop).
Win 8.1 x64 No NebulaMan right now, but tried 1.5 and I'm eagerly looking at the 2.0 development process .
