BR: T4 Crashes then eats driver for Frontier AlphaTrack

[Gymnopedies]

I may need to increase my asio buffer size, Not sure but when riding faders and recording the automation while switching back and forth between multiple tracks. T4 suddenly started popping then it ate my AlphaTrack fader strip.
to clarify, T4 did not crash but the Alphatrack went POOF.This happened at about the 8 min. mark into the piece.
Had to reboot to reinitilize the ATrack....
