Took my 14 inch elite book out to record a 3 hour show last night 24 channels of 24/48.
1x Steinberg UR 824 USB as master fed by
1x Steinberg MR 816 Adat
1x ADA 8000 Adat
Used windows 8 x64 and reaper x64( no dongle) . The O.S/ programs ran from the internal SSD and I recorded to the second internal 7200 drive which replaced the DVD drive
It all ran with zero issues, 3 hours of recording trouble free.
The 24 pre’ s were in a 3 u gig bag, the laptop is the size of a 13 inch mac book so all in all a very compact system.
Windows 8 with steinberg interfaces work fine
