Virus TI-1&2 need several restarts until any/normal sound comes out
Was having similar symptoms on my Mac Pro.
The only way I managed to get things running was to update to El Capitan.
i have upgraded to EI Captain too mate but i'm still having the issues, its so frustrating it's untrue and it absolutely kills any vibe you came with for making music, seriously gonna have to sell this thing if this carries on, £1500 we shouldn't be having these kind of issues at all
