I wrote a reply, but it seems to be lost... ohhhhhhhhh.
I started a new song in the key of C and entered an F# chord.
Result: F# stayed F#
Changed the key (no transpose) to F#
Result F# changed to Gb

Started over and tried changing to every key (no transpose)
The F# changed to a Gb in the following keys: Db, E, Gb, Ab, B, C#, F# and G#

Might this be a bug?

Thanks for listening
from Marty
