Me too "IRQL Not less than or equal"

My first one was immediatly after installing the Nocturn.

I guess I'll be uninstalling it untill they fix it.

It seemed worse with 7.0.9 but I could be wrong.

I have had this when recording knob tweaks with my SL.
On the Midi/Sync tab I changed the control surface from RemoteSL to None and the glitching stopped. The knobs still worked though.
Maybe try this?

As far as BSODs go i just posted here
