I have a Fireface 800 with Babyface connected via ADAT on a Windows 10 machine.  Is it normal for Totalmix FX to constantly be using 10% of my CPU?  That seems high to me, especially with no actual effects active.  Also, it says I'm running 32 bit.  Am I forced to that because of the FF800?  When I only had a Babyface, I could've sworn it was 64 bit.  Also running version 1.50 (3) of Totalmix FX.
