Which rebuild did you use?

Did you try the other rebuild, usually the slow rebuild?

Yours is an interesting problem. I have the 64 bit BiaB 2019 on two computers. One I use the fast rebuild as it has no third party styles and the other I use a slow rebuild as it does have third party styles on it. In both cases I can find _SWOON and _SKYLAKE.

As you know both are Realtracks so they will not appear when searching for MIDI only.

Whenever I get something stuck in the back of my throat, I dislodge it by drinking a beer.
It's called the Heineken Maneuver.

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
