Handling Song Changes in Global Rackspace

Don’t know why the callback gets called twice either. Using the UI instead of calling SetGlobalTranspose I get the expected callback value.

Well, I forgot about this, but it works so by design. If you try to modify the Global Transpose while in Setlist mode, it will be reset to the transport of your song. See the discussions, here:

Transpose feature goes back to 0 after a few seconds

I need to transpose my entire gig down a half step. I set it to -1 on the top transpose section and saved the file. After about 10 seconds it goes back to 0 when I switch patches. ?

It also explains why your callback is called twice. The first time because of your change, the second one because GP resets the transpose to make it match the one of the song.
